I had a problem like this once. In a heterogeneous array of 80 GB PATA drives (it was a while ago), the one WD drive kept dropping out like this. WD's diagnostic tool showed a problem, so I RMA'ed the drive... only to discover the replacement did the same thing on the system, but checked out just fine on a different system. Turned out to be a combination of a power supply with less-than-stellar regulation (go Enermax...) and the WD was particularly sensitive to it; nothing else in the system seemed to be affected Replacing the power supply finally eliminated the issue.
Hmm ... that could be the problem. Power supply is the only component that is not brand new. Just swapped it out for a spare. Will see how that goes over the next few hours.
Cheers!
