Western Digital Hard Drives - BEWARE!!!!!
IRVINE, CALIFORNIA -- At end-June, 2012, I bought two 1TB Hard Drives, to replace failed units. The two drives were placed in a RAID1 array: the contents of one drive are mirrored on the second drive. A few days ago, one of the drives failed. The computer still works, but there is no mirroring: the contents of one drive are not instantly copied to the second drive.
I called Western Digital, as these drives have a two-year warranty. Western Digital said they'd send me two replacement drives, as it is not clear that a RAID1 array is self-repairing. I appreciated that helpful approach.
However, Western Digital sent me one 500GB drive and one 1TB drive. To be used in a RAID array, the drives have to have the same capacity. Thus, these two drives were mismatched, and so useless.
Further, the 500GB drive was factory-fresh, while the 1TB drive was "re-certified". "Re-certified" means the drive had been tested, after having been returned to WD for some reason.
I called WD to ask that two factory-fresh 1 TB drives be sent. I do not want to trust my data to a "re-certified drive". Bear in mind, the failed drive was less than six months old!!
No luck. I simply could not find intelligent life at WD. One Customer Service Representative tried to convince me that a "recertified drive" was fine. I resent having my time wasted. At length, I concluded the warranty was worthless. I ordered two new 1TB drives, made by a different maker.
I finally found a Western Digital customer service rep, who had brains. I asked that I be sent two return labels, and that WD cancel the charge to my credit card. I was told these things would be done. I also asked that so soon as these things had been done, that WD wipe out all records relating to me.
I will not again use WD products. Their products fail. That isn't the end of the world. But WD's inability to honor their warranty is very, very disappointing.
