Descripción del producto
Enorme capacidad - Ya sea como disco duro externo o en una computadora notebook, las unidades Scorpio Blue de 2.5 pulgadas de 320 GB de WD ofrecen la mayor capacidad disponible para sistemas operativos que demandan mucho espacio como Windows Vista™, y aún les queda suficiente capacidad para fotos, música y video.
Silencioso - En un disco de notebook, el silencio es oro. El exclusivo sistema WhisperDrive™ combina los más avanzados algoritmos de búsqueda para lograr uno de los discos de 2.5 pulgadas más silenciosos del mercado. Estos algoritmos también optimizan la forma en que el disco busca los datos, lo que reduce significativamente el consumo de energía. Así es que ahora el silencio (y mayor duración de la batería) es oro.
Confiable y resistente - La tecnología ShockGuard™ de WD protege la mecánica de la unidad y las superficies del plato contra los choques. El sistema SecurePark™ de WD estaciona las cabezas de grabación fuera de la superficie del disco durante el arranque y paro del movimiento de giros, así como durante el tiempo en que la unidad está apagada. Esto garantiza que el cabezal de grabación nunca haga contacto con la superficie del disco, lo que contribuye a una mayor confiabilidad a largo plazo debido al menor desgaste del cabezal y una mejor tolerancia a choques no operacionales.
Rápidos y eficientes. - Con una velocidad de rotación de 5400 RPM, un tiempo de acceso de 12 ms y hasta 3 Gb/s de velocidad de la interfaz SATA, aún los clientes más exigentes apreciarán el rendimiento alcanzado por las unidades de disco Scorpio Blue de WD.
Probados para compatibilidad - En nuestros laboratorios FIT Lab™ y de Compatibilidad móvil, efectuamos pruebas en cientos de sistemas y en una multitud de plataformas para proporcionar a nuestros clientes la confianza de que nuestros discos funcionarán en sus sistemas.

I cloned my existing Western Digital Scorpio Black 250 GB hard drive onto it with some troubles. I had to fix some problems, because it didn't clone my Vista partition correctly, and the MBR was also corrupt. After fixing it, it worked great. For a while.
Then I decided to upgrade my other partition, Xubuntu, to 10.10. My computer froze in the middle of it and installation was messed up. The kernel loaded correctly, but now it's loading two copies of things: A version from 10.4 and a version from 10.10. I gave up fixing it, and decided just to re-clone to hard drive, since it would take less time on my part.
Second time, it cloned better than the first time, with no Vista corruption, and no MBR corruption. I decided to run 10.04 awhile longer, just in case.
Then it happened. It started clicking loudly while mounted in my laptop. It's still working, and from reading online, it's "normal", but it sure does make users like myself nervous. Usually, this sound signals imminent failure. However, it's reporting that the drive is functioning perfectly, though I'm not convinced. It frequently stops resuming from sleep/hibernate, both in Xubuntu and Vista. It would complete freeze in the process, and I have to do a cold power-off. In Linux, it would report that it failed to read sectors while resuming.
It got progressively worse. It stopped being recognized in my laptop. At first, I thought it was my fault, so I removed the drive and reseated it. It still didn't work. I tried again, and it booted. Then it froze again upon resuming from hibernate. It's now getting so bad, POST gets delayed and is unresponsive for about 10 seconds. When it finally POSTs, it'll indicate that no disk was detected.
However, if I connect it to the external enclosure taken from another Western Digital drive, it's recognized. Trying to boot from this drive while attached as an USB drive causes it to still freeze. Putting in my 250 GB hard drive back in my laptop, and everything functions correctly, including resumes.
The quick tests I ran using Western Digital's own tools claims that it's fully working, but I know this is not the case. It seem to work fine as an external drive, but it's not what I bought it for.
This hard drive did benchmark nearly the same as my 250 GB Scorpio Black. I'm just super glad I hadn't reformatted my older drive yet, since this hard drive seemed unreliable from the start.
Currently running the Western Digital's Extended Test on it. I'm expecting it to show bad sectors. This is after a reported 1.6 days of use, according to SMART. I've never had a hard drive fail this fast. In fact, I haven't had a hard drive fail on me in almost 10 years. Ironically, all but one were Western Digital.
From looking at online reviews after all these problems I'm experiencing, however, it seems like this is a very unreliable drive. A lot of the problems are caused by it's quick and frequent spin-down, which I'm attributing to my resuming issues. I'm also betting this is why I'm not having any issues when I use it as an external drive, since it's not spinning down when it's busy.
There are also a lot of other people reporting that the drive isn't being recognized, which mirrors my situation where my laptop doesn't see it.
I definitely can't trust any of my files to this drive any more after all these problems, so I don't think there's any way I can bring myself to keep it. I also can't recommend it for all the problems this drive seem to have. The space is nice, but I'd rather have a smaller drive, and have some comfort in being able to keep my data.
Packaging - Other reviews criticized the packaging as being inadequate for shipping. Perhaps because I ordered another item (a micro SD card) at the same time and the two items came together, mine was very well packaged.
Installation in the Dell Laptop - I needed to replace the nearly full 340 GB Seagate drive that came in my 2-yr-old laptop. Since the laptop accepts only one drive, I had to clone the drive, operating system, installed software and all. I didn't want to reinstall everything from scratch. I used the shareware version of Macrium Reflect which is available as a free download. A day or two before the drive was due to arrive, I made a complete backup of the three partitions on the original drive onto a 1-TB USB external drive. I also used Reflect to create a recovery CD. That CD is bootable using the Linux operating system. The process was easy to do, but took about 5 hours. It completed overnight unattended. The physical installation was fairly easy - be sure to take precautions against static electricity. I removed the battery, opened the computer, removed the drive and took the bracket off the old drive to use on the new one. Obviously, if you want to install this as a second drive, you'll need to have additional cables and brackets. I took digital photos of the new drive so that I could get any information I might need, but the information wasn't needed.
Once the drive was physically installed and the computer put back together and attached to the external USB drive, I booted the drive from the Linux recovery disk. Reflect starts automatically and directs you through the restore process. Just be sure to adjust the partition size of the active partition. The recovery took about 8 hours unattended.
Result - The laptop boots and appears exactly as it did with the old drive. All hardware, software and secured wireless access works without a hitch. The only difference is that I have 340-GB of free space.
I also can't totally rule out that the packaging of these drives was poor when they originally shipped (I seem to recall that they were loosely packed in a bubble-wrap envelope), so that may have had something to do with the failure as well. I'm hoping that the replacement backup drive I'm ordering now will be properly packaged by Amazon.
WD has a good Warranty, and I've had Warranty replacement from them in the past on other drives, as I mentioned. The problem is when I get the replacement drive back I've usually been hesitant to use it. This time it's a RAID, so I'd like to keep it homogeneous, but it's still an ongoing worry now.
Bought a new 2010 13.3 MBP (Mac Book Pro). Got this drive to upgrade it so i could run both OSX and Win 7 and have plenty of space for data.
1st drive was problematic out of the box. Many hangs etc. Ran WD's diags off the website - drive failed the quick test. Ordered another one from amazon and they refunded me the money on this one. I am amazon prime and love it since i can get stuff shipped 2-day at no additional cost.
2nd drive has lasted 2-3 months. booted system last night and windows had to do a complete chkdsk (BAD SIGN). found 4K in bad sectors (REALLY BAD SIGN) after taking 8 hours to fully scan and repair the drive.
Ran WD diags - drive passed short test but failed extended test. More bad sectors occuring hourly - eminent failure.
RMAd drive on WD site and they are sending drive #3 - probably another failure.
Just bought the WD 750 GB version from amazon (1-day) since i need to get up and running asap. Will use the new 640 for backup or sell it (backups need to be reliable).
Really wanted a different brand but seems like all 2.5 SATA at this capacity range have problems (check the web).
Definitely stay away from this 640 - lot of failures on the web.
I've been a fan of Western Digital (WD) drives for quite a number of years. I only utilize WD products when I need to replace a HDD (hard disk drive).
Recently, I purchased a Dell Vostro notebook with a 320GB HDD. I use it to record video and duplicate DVDs, host a I-tunes server, and as a repository for our digital photo collection. It ran out of storage capacity almost immediately (Win7-pro). So, I replaced it with the WD 640GB unit and have been very satisfied with its performance and storage capacity. The drive runs silently and boot-up and data access is noticeably quicker than the original model (320GB Hitachi Travelstar).
I noted within earlier product reviews that others had troubles with their units. My experience is wholeheartedly positive. My other notebook has a 500GB Western Digital unit and my experience with this is also highly positive.
I've had poor experiences with catastrophic failures and growing bad sectors with Samsung and Fujitsu notebook drives.
