I bought a 500 GB WD Passport. I have owned it for a few months. The date on the device shows January 28, 2009 (note that this is less than a year old). This Christmas, I plugged it in to my Macbook Pro, the only machine I have ever used the drive with, and the Mac’s attempt to mount the drive resulted in a message that says “The disk you inserted was not readable by this computer”. When I first plug the drive into my USB port, you can hear it whir then click then stop five successive times before the message pops up on my Mac.
The data on the drive is very valuable to me, and I unfortunately do not have a backup. I feel that Western Digital owes me an attempt to recover the data as well as a replacement drive, since it failed after less than a year of use.
