This review is from: WD My Book 2TB Desktop USB 3.0 External Hard Drive Storage WDBACW0020HBK-NESN
Pros: USB 3.0 interface.
Cons: At first, it wouldn't always connect on USB 3.0. Other drives and docks were fine. About 6 months later (20 backups - I keep count), these drives (I have two of them) stopped being recognized at all. One of them would sometimes be recognized as a USB device, but never showed as a drive in the system. These were my backup drives - fortunately I also have two large Seagate external drives which are (so far...) working fine. WinDLG couldn't see the drives on USB.
Finally fed up, I opened one of the units and found that the drive itself is a WD Green. I pulled the drive from one and found a discolored area on both the drive PC board and the mating controller/USB board - in areas that are next to each other with a thin insulator sheet. Looked like way too much heat and perhaps a bit of smoke. I'd post photos if I could. I then removed the USB/controller board and hooked the drive to a USB dock that works well with other drives. Tested with WinDLG and found "unknown errors" on the short test, and "failure due to electrical errors" on the long test. I could only conclude the drive was smoked or overheated & burned something up using the supplied WD power supply.
Not encouraged, I then opened the second non-working drive. This one showed very similar heat discoloration and black "soot" on the same boards in the same place as the first drive. Unlike the first drive, however, when placed in the USB dock and tested with WinDLG the drive actually ran the tests and showed numerous bad sectors.
Further inspection of the electrically-failed drive and the USB/controller board show some blackened pitting that appears to be arcing. This would indicate that the insulating material does not do it's job & there's some kind of design failure by WD on these drives. It's not the USB connector - it's in the vicinity of the activity LED.
Two DOA drives bought a bit of time apart. Both now dead. At this point, I may be able to recover one of the "green" drives from inside - but the total cost is much higher than if I'd simply bought the bare drive and an external dock in the first place.
Other Thoughts: I've now got a pile of bad WD drives, including a WD Red that lasted less than 6 months in my NAS. Four dead RE4's, one good RE4. Three good (so far) Red drives. One dead Green drive (this one), and one that may be recoverable but I won't trust it again. And a couple of others of various types and vintages. One of the RE4s was a factory refurb to start with, never again for that.
For what I've put into drives, these are no bargains. It also proves the need for multiple backups.
Pros: Small, low power, efficient, suitable as a "small server" or specialized box. Works well for Linux or BSD server or router.
Cons: Does not provide 12v on drive connector(s), so it's not for use with a Seagate Constellation 2 enterprise drive
Other Thoughts: Bought this for a BSD Unix server/router box. Wanted to use Seagate enterprise drive, but after discovering no 12v on the drive power connecter I ended up with a WD Black drive. Hopefully the long-term reliability will be good.READ FULL REVIEW
Pros: It weighs less than a desktop drive.
Cons: DOA. Doesn't even spin up. Not recognized by BIOS - in multiple machines. I expect DOA with cheap drives - this is an enterprise drive to be used in a server.
Other Thoughts: I should know better than to order just one drive. While I've had good luck in the past, it has now run out (I usually buy WD, but this drive got lots of eggs and was at right price point for enterprise drive). This will be RMAd in the morning.
That said, I may be done ordering drives from Newegg. They were kind enough to put the drive in a box, inside bubble wrap, but it was NOT in an anti-static envelope. That would cost a whole penny, but would save the chance of a bad drive and RMA. While I don't know whether it was the issue here, this is the first time I've ever gotten a drive from Newegg that was not in anti-static.... and the first time I've gotten a DOA drive from Newegg. Drive packing has been iffy in the past - this time it's worse.
So instead of completing my new Linux box this weekend, it'll have to wait until sometime next week. Disappointing, even more so because the local competition doesn't stock enterprise-level drives.
