Summary: I know these hard drives are refurbished but I buy Western Digital because of their quality control and reliability of their product. Given all the negative reviews, this many DOAs are unacceptable.
Pros: Bought two. The one that works passed a long test and functions as it should.
Cons: The one that is bad makes clicking noise right out of antistatic bag. Not recognized by bios. Unable to run tests. Had to DOA right away.
Summary: I purchased this drive from Amazon. It lasted a little over a year, then died. Since I had been using Western Digital drives exclusively since I started building computers in the late 1990s, I assumed that this was a fluke, and I purchased and installed another one, same model as the one that died. The second one lasted a year and a month before it also died.
Summary: I bought this one in 2008. In less of two years it stopped! At first everything was OK, but before a year of use, my computer said "the disk is very damaged and recommended change it", in that times, bug reports indicated that in Palimpset (disk tool of Ubuntu 9.10) had a bug reading S.M.A.R.T. showing warning messages by mistake and Windows disk tool didn't detect anything wrong, then ignoring the Ubuntu warnings, I kept using it.
