I have two identical WD20EARS drives, both about 3 months old. On one drive I have had several failures with the message in the thread title. On the other drive, connected to the same USB dock, I have never had a single problem. On the drive with the problems, I have run all of the WDC tests without any failure (or at least I think without any failure, the results are hard to read). Since one drive works in the same dock and this one doesn't it has to be a drive issue but I can't prove it by test results. If I send this in for warranty will it be taken care of?
