WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black

I bought this to enable the time machine features on my Mac computers. I have the new Airport Extreme, and I was looking at the Time Capsule from Apple, but I was hesitant at how much money they cost, and the fact that you can't upgrade their storage capabilities. So, I did some reading to find that you can add a USB hard drive to the Airport and get the same features. I limited my search to USB3.0 because many of my machines are connected with 1Gbps wired Ethernet, and I want the backups to be fast. Well, I am not disappointed. If I backup with WIFI it is actually not that bad, except the first backup, which is many GB in size. Otherwise the incremental backups are pretty quick, wired or not. So, this is a single 4TB hard drive in an external case. I can't believe this costs less than $150. It is amazing. Anyway, connected to my Airport the drive powers down when it is not in use, so that I know it will last a long time. It takes a few seconds to power up when I am ready, but this causes no real issues. The installation was a breeze. I plugged it into my Airport, opened the app. Went to the File Sharing and Disks tab, and added the disk. That was it. From the Mac I went to time machine and picked the shared disk as my backup, and it even recognizes it as a Time Capsule. I also use it as a network drive. Why not, it is HUGE, right? It is really quick, and has never caused me a problem. As a result, I get incremental backups on a near hourly basis. I can get the state of a file from days or weeks ago. I feel really safe with this. My old MacBook died, and I got the new MacBook Pro Retina, and I followed the restore from backup option, told it to not mess with the OS, just the apps and the saved files, and when it was done I had everything back. What more could you ask for. For under $150, the piece of mind I get for having 4TB worth of incremental backups is huge. I got the same drive and setup my parents to backup both of their computers on it. It is plenty big for this, too. They are thrilled. [...]

I purchased this drive largely based upon a specific need for a USB 3.0 product with 4TB of storage. I've owned many WD internal and external HD products over time and have not had any drive failures to date over many years. I purchased this drive specifically as a backup storage drive attached to a Synology 1813+ NAS unit. This required a reformat to EXT4 as the drive comes natively formated in NTFS. The Synology NAS schedules backup to this drive of selected folder shares using the "Time Backup" software available from Synology. I'm not utilizing any of the software included from WD with this drive (backup, cloud, etc.) as the Synology NAS has its own software for each of these purposes. The drive itself is similar in size to other My Book drives. The plastic casing is certainly not as nice as the aluminum finish on the WD My Book drives that I have for my Macs, but it is similar to the black of the Synology unit and overall looks good. The power adapter is reasonably sized (not a brick), and the unit comes with a USB 3.0 cord for use with its single USB 3.0/2.0 port. WD provides a 2-year warranty with this product. There are cheaper drives with similar specs available from other companies. However, having had drive failures with Seagate over the years, I'm unwilling to take chances with other options. It's important to backup your valued files, and WD drives have played a major role in my backup solutions over time. If I have issues with this drive, I'll update my review. This seems to be another winner from WD! Edit/Addendum: Following my review, another Amazon user asked me an excellent question, "Does the USB connection to the drive feel flimsy?" This is a very appropriate question given concerns raised with the prior generation of this same My Book device. While I don't own the previous My Book version in question, I did check the USB connector on my device. The supplied USB 3.0 cable seems to be stable in its connection to the rear port of the My Book case. I can't physically make it move horizontally or vertically with any significance - unless I were to apply excessive force. Modest attempts at movement of the USB cable did not disrupt the connection. I don't plan to move this My Book from one place to another (it's connected to my NAS), so I suppose that I won't be able to comment well on wear-and-tear issues with respect to the USB connector. Other My Book devices that I own are the Mac Firewire/USB 2.0 version. Those have never struck me as flimsy. Update 1/18/14: Since writing my original review, I've purchased a 2nd unit which I reformatted for Mac OS X and use for "time machine" backup. Both drives are functioning well and have had no issues. I'm still very pleased with the quality and function of the drives. Reading through a number of the questions regarding this drive, it's clear that the term "cloud backup" as assigned by WD to this drive is a bit of a marketing stretch. As has been noted by others, the "cloud backup" option is not intrinsic to the drive, but an add-on service provided by Dropbox and facilitated by WD software that a user may choose to run on an attached computer (I don't personally use or recommend that others use WD software). These drives are nothing more than a WD drive, in an enclosure, with a single USB 3.0 connection. If you are looking for "cloud" capability, other product options do exist. I do hope that WD changes its description of drives such as this in future marketing.

time to buy another one! I was worried this woudl arrive DOA .. that these precise instruments were too delicate to be tossed around by ups or usps. but it arrived.. and worked .. and is working fine.. 4 TB (3.75TB) is nice. They hold so much info tho.. a failure would be catastrophic so i'm going to buy one just to back up stuff i already have. (the only failure i have had with these so far is when i dropped one that was spinning 3feet onto hard surface.. it continued to work till powered off.. but it never booted again.. I have 4 variations of this on my desk.. and i will buy several more in the future.. only drawback (other than if you drop one that is powered) is that they sleep when not used.. so when you go to use them you have to wait 10 - 15 seconds for the drive to spin up. This is a noticeable irritation.. but preferred to having the drives fail sooner.. they all seem to run quiet and cool.. in my history of these things i have had one failure (other than my catastrophic droped one). but it was not the drive. it was it's power supply.. (i had the leftover power supply from the one i dropped tho so i was saved!) .. that reminds me i need to check on amazon for buying a backup power supply for these. (the one i dropped was my oldest and first drive 750GB.. its ps was higher amps than the newer ones.. the newest ones are these 4 TB versions. These are precision instruments and should NOT be moved while in use.. I Dont know if drives park themselves these days.. (remove heads from platters for transportation and handling) but i would always disconnect the drive in windows.. before handling it.. and even then only when power is off to it. the drives spin very fast and gyroscopic forces would probably ruin the drive if you just moved it around while spinning... and 4 TB of data is a LOT to lose! I have 5 of these now.. and will continue to buy them.. i love these drives. amazon has the best price too i think.

Basically I purchased this drive to make a backup of data on my original wd my book live duo which is running RAID. Basically the data on the drive is not data that needs to be updated on a regular basis, It's just videos, pictures and some music. The drive maybe connected for about a week or two to do a backup and then disconnected and put away in the event I need the backup. Once I copy all data to this drive I then verify the data by re-copying the files to a different location to make sure that I can get my data back. I've had one of those wd my book live duo with RAID go bad and had to return the entire unit. After I received the replacement, I recopied the data from the usb drive that I kept in a safe place onto the replacement wd duo drive. The process of backing up and restoring my data went by pretty simple. Unfortunately the original USB drive (Seagate) died after four months and was sent back for repairs/replacement. I have no idea when I'm going to get that replacement back! Anyway, I'm using Windows 8.1 with a system with usb 3.0 ports, I had a problem connecting the drive cable to the actual drive. The connector on the drive arrived bent and I had to pry the connector on the drive a little wider so that the cable would fit in it. Before I give any speed info on the 4TB WD My Book USB 3.0 let me give you and idea of my system and network configuration first. Intel i7 3770 3.4GHz Intel DH77DF ITX Motherboard Crucial Ballistik 16Gb DDR3 PC3-12800 Memory Intel 335 SSD 240Gb Hard Drive 6Gbs Antec ITX Vesa-110 Case Windows 8 64bit Upgraded to Win 8.1 Onboard Intel Pro Gigabit Ethernet Cisco/Linksys E3200 a/b/g/n Gigabit WiFi Router Belkin 5-port Gigabit Switch Cat 6 Cables 3 - 4Tb My Book Live Duo Running In RAID (Gigabit Connection) 4 - WD Live Media Hub 1TB (Gigabit Connection) The info is based upon the speed shown under the Win 8.1 file copy details. The files are approx. 500mb up to 8Gb in size and everything is copied to and from the WD 4TB USB 3.0 external hard drive. (The test was done using 200Gb of the same video files for each test). I noticed the speed would drop a little as it started to copy the next file in the queue but it would regain full speed after a couple of seconds. Reading data to and from the 4tb wd usb 3.0 drive was basically the same for each port or internal drive tested. Here are the reading I got: Using Gigabit Ethernet to the WD 4tb connected to USB 2.0 Port Min - 24 MB/s Max - 38 MB/s Using Gigabit Ethernet to WD 4TB connected to USB 3.0 Port Min - 43 MB/s Max - 68 MB/s Using Internal SSD 6GBs Hard Drive to WD 4TB connected to USB 3.0 Port Min - 59 MB/s Max - 76 MB/s Basically reading and writing from the WD 4TB USB 3.0 gave me pretty much the same results. In my opinion; for an external drive it seems to transfer files pretty fast and I'm able to move 2TB of video files over Ethernet to this external drive in approx. 7-Hours, Usually when I use a USB 2.0 port it takes almost 15 Hours. The only problem I found was the USB 3.0 port on the hard drive needed a small screw driver to force open the metal connector that was not allowing the cable to connect to the drive. This was a real bummer if you're not a DIY or careful type of person then chances are you'll be returning the drive since one false move and the inside plastic connector of the USB female end on the drive could end up broken voiding the warranty. The next thing I found is that the drive may takes a couple of seconds to spin up from sleep mode which it seems to enter quite frequently, maybe some folks may or may not find this annoying. Some folks may say the are having trouble waking the drive as a share when it goes to sleep as a network drive but I've not experienced this problem on mine so far. It may take a little while to respond from sleep mode but it does come up after a few annoying seconds later. I hope this helps you understand what you're getting if you're planning on purchasing one of these drives. In closing, I'd say this is a pretty decent drive although it could be a bit cheaper on the price in regards to the Seagate central 4TB USB 3.0 but I've already given up on the reliability of the Seagate drives to even consider them.

NOTE: THIS REVIEW WILL COVER USE ON THE XBOX ONE ONLY. As X1 owners will understand, the internal hard drive isn't anywhere large enough to hold many games, now hitting the 30GB range. Just by installing 3 games, over 30% of my space was used. Not good, so an alternative was necessary. I chose the My Book line over the My Passport because I wanted the unit to stand as it's shown in the picture, which is necessary due to my setup. The My Book stands about 2x higher than the console vertically, but can also be laid atop horizontally, if one chooses. The unit requires additional power, so be prepared to find another outlet. The built-in transformer makes for a larger plug, so if you intend to plug into a surge protector, you will need to be aware this may not fit among other plugs due to its size. I've only had this unit for about 2 days, but so far, it's working perfectly. For XBox One owners, here's some basic information: -When you connect the drive and turn on the console, you will need to go into Settings - Manage Storage to prepare the unit. The console will automatically detect the new USB drive. -You will need to format the drive before you can use it. Start the process. The console will ask you to name the device, if you wish to do so (I named mine Pipboy 3000). The format takes less than one minute. -The final question will ask you if you want to use the device as the primary drive. I recommend this option since every download and save will go to the external drive rather than the internal drive. You can always change this option at a later time. Transferring (moving) games from the hard drive to the ext drive is pretty easy and straightforward. Ryse was the only game that took a while, but that's because it's 30GB in size. Despite the size, it still moved in less than 4 minutes. It's important to note the drive speed is irrelevant here. The 5400 RPM isn't going to be used to its maximum since the USB 3.0 is what will control the speed of data transfer. That said, I did not notice any additional time being added to loading screens (Assassin's Creed IV). If you're looking for additional space, I recommend this unit. Remember: this is only valid for the XBox One through experience. PS4 owners should do more reading to ensure the drive will perform as expected. Thanks for reading and have a great day.

Thinking about one? No, don't think, just buy it. Just do it. Plug it in and you're done. ►APPEARANCE: Small and rather unnoticeable. ►WHY I BOUGHT IT I already owned a WD 1 TB external. This just increases my storage space to 3 TB. My 500 GB hard drive is only used to hold desktop wallpaper. It maintains, & runs programs needed programs. ►SECURITY Ever think about a crash? This prevents important or private files from deletion. You can also backup your computer to a WD external instead of the default D drive. Also remember that nothing says "no" to a hacker better than an "unplugged" WD external drive. This will fit into your bank's safety deposit lock boxes for a lot less per year. ►USES Why pay yearly for access to a cloud? Worried about a lot of sensitive files? Have a lot of family photos or ancestral information? Do you have complicated taxes? Run a small web company as I do for select people? Old email you'd like to pull up? Do you play an instrument and save tracks? Vacation videos not yet put on DVD? If you have something that is so prized that you dare not lose. Put it on a WD external, a DVD storage disk, and flash drive. Triple security. ►I just thought of this. Fonts are memory thieves. You and I know that there are fonts you don't use often or maybe at all but do not want to delete them. Keep the ones you absolutely need and that the system needs... and house the rest on an external drive. Also, music files can be placed in there and accessed as if on your pc or laptop's C drive (main drive). Get a good 5GB transfer rate multi-port USB hub and go. I have these two externals plus a 32 GB and a 16 GB thumb or flash drives all plugged in all of the time while I'm using my laptop. Sorry. There are no cons for this product.

I have an older computer and need some backup to find room for the movies I'm downloading as well as backing up my drawings and documents. This device is not ideal for that purpose. Pros: quiet (most of the time) can go into standby (as long as it isn't automatically backing up anything AT ALL) Runs cool, looks good, nice and stable on the desk. Cons: the software sucks big time. Good for a total newbie maybe since it seems aimed at the user who wants to back up all classes of files like movies, documents, or photos, but for someone who just wants to back up specific files, not so good. Source Forge has much better software (for free) IMO. Some of my gripes is that the software prevents my XP machine from going into standby - even if it is set to back up monthly, it will keep the computer on 24/7 just so it doesn't miss its allotted backup time/day? It wants to phone home even when I turn off the automatic update and is running in my task list even when it is told not to turn on via windows msconfig "startup" programs (so it must be running from the registry) Windows treats it like any other usb storage device - so every time I power the computer up I have to look at the silly windows prompt that wants to know how I want to use the mixed files on the F/G/H drive it happens to be - and when I want to unplug a flash drive I have to consider that I'm turning off the drive I really want and not the "my book" Performance with USB 2 is glacial to say the least. Copying from the My Book to a flash drive is a reason to find something else to do since it may take hours. Then I come back to find Windows hung up wanting to know if I really wanted to copy the one Read Only file, in a group of files. Grrr... The drive I got is noisy. Makes a high pitched uneven whirring sound. The reason I left WD drive ages ago is that they were unreliable. I can use it, but find myself unplugging the power supply since there's no on-off switch and I don't trust it. Plan B is to add a PCI to ESATA card, and external ESATA drive, and junk this piece of detritus, and put a Samsung or Hitachi drive in the ESATA case. My old solution was to just use USB2 powered portable drives and put them in a safe place when the backup is done - the My Book is more hassle IMO. Just for the hell of it, I went on line to see if I could open the case and install a power switch on the front. The two utube examples I found turned out to be made by professional data-recovery specialists - that certainly doesn't bode well. Since writing the above I implemented plan B and that has proven far superior to the WD My Book. My compact IBM Think Centre was pretty well maxed out with 2.5" SSD and 1 TB 2.5" drive packed into the slot for one full size drive (all it was designed for). I added Vantec 6-Port SATA II 150 PCI Host Card, for 4 Sata drives with 2 external eSATA ports, and a Sabrent 3.5-Inch SATA/SATA II to USB 2.0/ESATA external enclosure. Windows treats it like a normal hard drive with its own assigned letter, windows can put it in standby if I'm not using it, and all the hassle with the WD/Windows software is out of the picture. If you already have a spare SATA connector/port on the mother board you only need the $20 enclosure and not the $25 PCI card - although you still need an adapter to go from the SATA connector to a computer mounted external eSATA connector (same game just designed to be sturdier) The external enclosure came with cables for both the eSATA and USB connectors (so I can move files via the USB port if the need should arise. The only complication with Plan B was that I had to use the disk manager in windows and reformat the 80 GB test drive to NTFS before windows would use it. The Vantec card was shipped with a CDROM for RAID data backup (if backup was your interest in getting a My Book, but like I said Source Forge has lots of good free utilities if that is what you need) In retrospect, I'm sorry I wasted the money on the WD My Book. I guess I can pop the case on the MY Book and transfer the hard drive into another eSATA enclosure so it won't be a total waste.

The last Western Digital Mybook I had was a 1TB that my father handed down to me. He bought it in 2007 and it lasted until 2011. That is pretty amazing. Though I might add it was used as a backup drive for his mac. Regardless, the drive was always plugged in and would do 1 hour backups 24/7. So while massive amounts of data were not being transferred 24/7, the discs would be spinning constantly. I used his MyBook for my own mac. For my uses, I transferred movies onto it and filled it to capacity. We had a scare when it stopped working in 2010, and I decided to try taking out the hard drive from the enclosure and putting it in one of my hot-swappable external hard drive bays. Turns out the connection ports on the MyBook fried or the soldering just cracked and lost connection. So I always check now when a drive "dies" before drilling 1/4" holes into it and tossing it in the trash, to always test it in an external drive bay to see if it was bad/aging soldering first. To get a better idea of what an external bay is, here is the one I bought Plugable USB 3.0 SuperSpeed SATA III Lay-Flat Hard Drive Docking Station (ASMedia ASM1053E SATA III to USB Chipset, UASP and 6TB+ Drive Support) . Anyway, from that moment on I've been a fan of WD and bought many an internal hard drives from them since. Now, this black friday I wanted to buy a huge capacity hard drive to store my uncompressed blu-ray movie libray in. First run though was going to be with my anime collection. I was torn between several factors: 1) should I go external or internal? * 5/10 years ago it made sense to buy a huge internal hard drive and put it into a docking bay for a fraction of the price of a portable drive. Portability (without a power supply) was a luxury few could afford. Now the portable drives are slightly cheaper than buying the bare bones hard drive and already include an enclosure! 2) If I went internal, WD offers several different drive types (Green, Blue, Red, Purple, Black, etc.). All with supposedly different features (durability, energy consumption, quietness, speed, etc.). Was it all bologna or was it a significant difference among each other? Would playback of my Hi Def movies be bottle-necked in any way if I chose the "wrong" drive type? 3) Of all external HDD size options (and constantly decreasing $/GB value) what size external hdd should I get? * With many external hdd prices, the higher the capacity, the less you will spend per gigabyte of storage space received (up to a certain point) 4) Of all the externals out there, should focus on value $/GB or brand reputation? Or a mixture of both? 5) Which externals seemed built to last/dissipate heat best? So all these questions plagued my mind for a good month, before the black friday deals kicked by butt into gear to take the plunge. I could buy a 5TB drive from Seagate that cost $129 - compared to a WD Mybook 3Tb for the same price. That's 2TB more!!! But...that's WD vs Seagate. Here are some things you should know that I read from many people's reviews. Firstly, Seagate gives you a warranty for your hard drive BUT only will replace your drive with a REFURBISHED hard drive. First of all, why do they have so many refurbished hard drives lying around? Exactly how reliable are those previously used drives? There's no carfax for hard drives. Would you buy a used car off craigslist with no history or record to entrust your life with? Then why would you entrust your valuable data, pictures and videos with a completely unknown used hard drive? Second, Seagate will charge you money to have their technicians look and try to restore your hard drive. Or they will charge you for software that will try to restore bad sectors of the hard drive. Does not sound like much of a warranty to me. I'll share a personal experience with you. I have a roommate who bought some big capacity Seagate external drives for his anime. The hard drive failed after 10 months and 3TB of data he had were lost because the policy with Seagate is: return the unopened/unaltered drive to use for a refurb or possible recovery of the drive. I told my friend to let me take the drive out and put it into my docking bay to see if its a soldering issue or if the drive is indeed dead. He elected to use Seagate's warranty and lost his info. FYI, NEVER give your hard drive to anyone. Whether they be Apple, Seagate, WD, etc. If it has files on it that you would never consider posting to the world wide web, don't let it leave your home. The right people can copy select information faster than someone at a restaurant can copy your credit card info and buy something from Willie's Hubcaps LLC. in Jamaica, NY! Just don't do it. Anyway, it happened to the refurb hard drive he received and after that, he went WD. I know I'm bashing Seagate right now, but I'm not completely endorsing WD either. I have a Seagate 320Gb portable since 2010 that is running to this day. But it is the model that is comparable to WD's passport series. So it's not a high capacity drive. I have seen many poor reviews for both Seagate and Western Digital so you cannot simply go for review counts alone. To be honest, the best drives I've used are the Hitachi drives in macbooks. They have lasted me almost a decade in every mac I've bought and I run them hard. But have not found a high capacity Hitachi for prices that I can get from WD or Seagate, so I have to go with one of the popular guys. I am supporting WD because every. single. drive I've bought from them has served me 3-6 years and I have not been displeased in the least. Every hard drive has a lifetime. And I buy new hard drives to replace the aging ones. Just a part of life. So with that said, my personal recommendation is to steer clear of Seagate if anything for their warranty policy and customer service. I'd choose a Toshiba over them. But I digress. After all the headache of comparing WD internals vs externals, etc. etc. I pulled the trigger on the 2TB capacity. 1TB you're just losing money. 6Tb you're paying also way too much. 2TB-4TB is the sweet spot for the WD MyBooks. *** As of 12/05/14, the price of the 2TB drive is $96.99. I DO NOT suggest buying this at the current price. Yes, it's a good price compared to 5 years ago, but I paid $89 for mine. Besides, the WD Elements Portable 2Tb drive is $87 (I personally don't like the WD Elements line though, stay away). I'll let you in on a well known secret, the price of storage in the 2000s was $14-9/GB. In 2005, $1.15/GB. In 2010, $.07/GB. Now, it's about $.03/GB. Pennies on the dollar. It will continue to decrease. There is NO REASON (short of an emergency drive failing on you) that you should buy an external drive between Black Friday and Christmas. Wait for the holidays and then take advantage of the deals. Most of all, during Black Friday the hard drive I got was not even a featured deal! It wasn't even advertised widely as some other products on amazon. So I'm lead to believe $89 is the best/most accurate price you can get the 2TB WD MyBook for. By Christmas I'll wager it decreases to $75. Anyway, this drive performs very very quietly. It does not get hot. Transfers are about 25MB/s when connected to my usb 2.0 computer. But I know they will be faster when connected to a usb 3.0 port. It runs on mac and windows without installing any additional software. I would not recommend installing the software that it comes with unless you want to use it exclusively as a backup drive to your main computer. If you have mac, all you need is time machine (don't install anything). Regardless of OS, install the universal firmware updater. Firmware updates are good for hardware and you should make it a habit of checking for updates released periodically. For windows, install the WD Smartware. For some reason, when plugging into my Win 7, it does not show me an option to eject the external drive. So I downloaded and installed the WD Smartware and when the program opens, I right-click on the picture of the WD MyBook and then can select eject. But only within that program. You do not want to yank out the cable or shut down the computer and yank it out. You always should find a way to specifically tell the computer to stop communicating with the device and eject it. **** Tips I always use for Storage Mediums ****** Once you get your WD MyBook, I highly recommend reformatting it before you install anything. Reformat it to exFAT. This way you can OPEN and SAVE files of ANY SIZE onto the hard drive whether you are plugged into a mac or windows computer! I never thought I'd use windows until I had to and I was in deep doo doo. Better to be safe than sorry. Fat32 is universal too but means you cannot save files larger than 4GB. NTSC means you can OPEN files on your mac but can't save to them while you can OPEN and SAVE files while on windows. It's technical I know. Sorry. On Windows, choose an allocation unit size depending on your use for the hard drive. **Allocation size can be confusing but I'll try to explain it as clear as I can: Imagine you are moving to a new house. The condition: 1) Everything you own must be packaged in a box of the same size. The sizes are iPod, Teddy Bear, Bicycle, Refrigerator, and Grand Piano. You can choose only one of these. 2) No matter how big (or small), it must be disassembled to fit inside those boxes 3) Each box can only have ONE item in it You have a nearly unlimited supply of boxes. Let's say you choose iPod-size boxes. All your small items will be able to fit snugly in each box. But bigger things like your grand piano would have to be chopped up into so many pieces that it may take 20,000 of these boxes alone to package the musical instrument! While each box is filled to the fullest, you will have to unpack 20,000+ boxes when you get home! Let's say you choose Grand Piano-size boxes. Your piano can fit in it and utilize 100% of the box, but what about your salt shaker, iphod, shoes, and basil plant? They will each require their own box- the size of a grand piano!! You will have less boxes to unpack but have only 5% of the box utilized. So unless you live in a piano warehouse or ipod factory, you will something in between. The Bicycle Boxes for packing. It is a happy medium between better space management and less boxes to unpack when you get home. I live in the piano warehouse (I save 50GB movie files only!) So I choose the LARGEST allocation size possible. If you just want to backup your computer, you have 1 grand piano and 1 ipod, among other things. You choose MIDDLE-OF-THE-ROAD size. If you transfer only your photos & music, word documents, and other tiny files, you live in an iPod Factory! You want the SMALLEST allocation size possible. I have a mac but I run Win7 via bootcamp. So I formatted by WD MyBook to exFAT. On the same windows I selected an "allocation size" of the largest possible size allowable (for the capacity of the external hard drive). I forgot what I chose, but if you are on Windows, then select the option at the very top. The further down you go, I believe the size [of the imaginary boxes] will get bigger. Overall this drive is quiet, does not make weird noises, and stays cool to the touch all the time. Those Seagate externals are extremely flawed design wise. The new line they released offers improved airflow, however the vents are at the bottom of the external enlosure! Heat travels upward, the vents should be on top! (Like this product) The Seagate Backup Plus 5TB Desktop External Hard Drive with Mobile Device Backup USB 3.0 (STDT5000100) not only has a bad airflow design but the corners are extremely sharp many reviewers are saying (keep away if you have children and animals in the house?).

Delivery was prompt. The hdd worked as expected.

Compre este disco duro especificamente para usarlo en mi Xbox One ya que habia visto reseñas de el en internet, y vaya que es muy bueno. Lo compre en foerta a un precio muy bajo, por lo que me costo hubiera comprado uno de la mitad de capacidad, usa corriente electrica por si mismo, para algunos eso es un contra, pero en realidad permite que el disco gire a mayores revoluciones y por lo tanto lea y grabe mas rapido. Para un Xbox One solo conectalo y listo, funciona a la perfeccion

Works beautifully on my Xbox One. Visible difference in loading times.

この製品を2015年10月に購入し、Macbook Pro13 Mid2012にて使用していましたが、8ヶ月ほどで急に接続が途絶えたりとアクセスが不安定になってきました。 そこで修理を依頼したところ、「良品との交換」となり、アメリカからそれが送られてきました。 その後しばらくは問題なく使用出来ていましたが、交換から2年10ヶ月ほど経過した2019年4月に、突然アクセス不能となってしまいました。 市販のディスクユーティリティー等を試してみても認識できず、内部に保存されてあるデータは結局取り出すことができませんでした。 異音やアクセス不安定などの症状があれば新しいHDに交換するのが常識ですが、そのような前触れ無しにいきなりアクセス不能となってしまうようではWD社のHDを再び使用する気にはなれません。

I confess to not having spiked it in via the usb 3.0 yet, however the unit appears 100% and should perform as robustly and reliably as all my other WD products, NONE OF WHICH (Western Digital only) I HAVE EVER EXPERIENCED A PROBLEM WITH!! I can only say this about Western Digital products - others hard drive manufacturers like Samsung hard drive division (since bought by Seagate, which subsequently was then bought by Western Digital) have in past proved dismally unreliable, and customer service was lacking in my several experiences with these brands, as well. G-Tech, now owned also by WD, proved the worst ever experience, worse even that the dismal Samsung and the dismal Seagate. And it wasn't even about the products, which are ok. It was the executive attitude there at G Tech in California toward us global consumers (distrustful, arrogant, smug and self-satisfied, and blatantly outwardly hostile) that gave me the utter creeps, as I experienced a certain executive at that company (G Tech) who was downright sleazy and paranoid when I dealt with her on a matter related to their product line - I own 4 G Techs, but would never bother with that brand no matter who owns them now, as the company's core team as represented by this key marketing employee has demonstrated some lousy attitude toward customers, I discovered. Lady Marketing exec at G Tech, if you read this you know who you are and you simply suck as a brand builder and aren't half as smart as you think you are, you smug wonk. I will never forget that B%^$#& executive at G-tech and I hope her bosses threw her to the curb by now like yesterday's trash, for she is indeed a true brand liability. She knew so little about the technology she was representing as a Marketing head, and it was via her that I realized how far we consumers are being conned on pricing for these basic peripheral, and how little we are respected and valued by the executive team that gets paid the nice salaries there at G Tech. Get over yourself lady Marketing head at G Tech, you know who you are and yer shi^ ain't that special. She reminds me of the scumbag cd music execs at the big name music studios from an earlier era who were disdainful of both consumers and the recording artists as well – just give them their go^da8n money and everyone be damned... G Tech execs are just not likeable people, I discovered. They have issues. Moving on... WD is the reliability leader in the external hard drive realm. So assuming this WD unit performs as it should (which I have no doubt it will), I will comment on the speed of the Amazon transaction itself... It was expedited with great efficiency and precision. Yet another win for Joe Consumer, as this unit was at a "great" price point. Now if this general product category would only begin to lower its prices and keep them there, I would be thrilled. As it is, one has to be patient until such a deal as this price point makes its appearance. I feel these hard drives are generally selling here in Canada for more than is necessary for WD and the others to turn a profit, and I wish they would rethink their pricing strategy to enable consumers to avail themselves more of this technology with less concern for the high prices. More units sold (greater economy of scale) will net WD great profits and will benefit consumers simultaneously, as opposed to socking it to us with these (on average) $250-$300 per 6TB drive prices... this reminds me of the way the cd was used to exploit / extort the western consumer into parting with more cash than was necessary to purchase a simple prerecorded cd. The vinyl album pricing (moderate expense) soon enough gave way to the duplicitous collusive industry pricing of the cd industry, which became something of a rip-off. With external hard drives, they don't need to go for the kill price to succeed, but these consolidated hard drive manufacturers (and WD owns quite a few recognized hard drive brands under its umbrella). In my opinion, the industry jacked hard drive prices some years ago complaining their manufacturing infrastructure in Thailand was compromised due to destructive typhoon. OK, boys that ship has sailed long ago and you have your Porsches parked in your garages and your new home renos done now, so lay off on the overheated prices for these pretty basic pieces of modern technology that will in some few years essentially be obsolete tech. OK I'm done now. But WD does make a great hard drive regardless, so buy WD as they have earned this loyalty.
