Summary: Its not often that I take the time to write a review on a product, but I had to do it for this drive. I have been in the IT field for over 20 years and though I have seen it all. I purchased 3 of the 2TB Black drives in the last month. One here on Amazon and the rest, somewhere else. Out of the 3, 1 was DOA, 2nd died in 3 hours and the last, had so many bad sectors that WD's own software ran for 13 hours and it finally gave up and errored out.
Summary: I have read of others that have had hard drives fail and yet in many cases I still see an average or better rating for the drive. I just don't get that. In my case, this drive started giving S.M.A.R.T. errors about a week ago which Windows recovery with chkdsk /f seemed to overcome and which allowed me the opportunity to back everything up (that's a good thing) and run normally until the next time I needed to reboot. Then the system would just hang.
Summary: The drive mounted ok and the read/write was acceptable but OMG the thing sounded like a pack of mice were inside gnawing metal. There was such a huge grinding of metal on metal I'm sure it's defective. It's going back.
Summary: If you happen to buy one of these drives made in 2010+, WD has modified the firmware to prohibit the use of TLER (time-limited error recovery) software necessary to use these drives in typical RAID configurations. Why? So WD can sell you their RE3+ (Raid Enabled) drives that typically cost 50% more. Drives made in 2009 probably allow WDTLER to work.
Summary: I bought this drive for extra storage. I've installed many drives with no problems so it never occurred to me to worry about the quality of Western Digital's tech support. The drive works, but only under the right conditions. After trying everything I could think of, including flashing the motherboard and controller BIOS, installing the latest drivers etc, I contacted WD tech support.
Summary: Extremely disappointed, the drive was shipped without and protection and arrived dead, it was packed loose in a oversize box.. When I opened the box I immediately wondered if it would still work.. You can check my history, I am not a complainer and accept this as a total loss. Not even worth my time to send it back.
