Has anyone seen a situation where a SCSI adapter has blown up multiple hard drives?
At my place of employment, we have a server that used an Adaptec 2940UW SCSI adapter and two (mirrored) 9.1 gig Western Digital SCSI hard drives. One of the drives failed, so I just switched the cable from the main (failed) drive to the secondary drive (the mirror). I then ordered a replacement drive (under warranty from Western Digital) with the intention of re-establishing the mirror when the warranty replacement arrived.
Everything was peachy for a couple of days, and then today the second drive died as well. Of course, we have backup tapes, so our data hasn't been lost. But, in retrospect I probably shouldn't have switched the cables; I maybe should have reconfigred the machine to boot off of the second adapter instead. It justs didn't occure to me that the adapter might have caused the problem. Is this possible? What do you guys think - is it more likely that:
1. The second drive dying two days after the first was an unfortunate coincidence;
2. The SCSI adapter probably killed both drives (if this is even possible);
3. Maybe the power supply killed both of them.
Anyone's ideas or experiences would be appreciated. For right now, I'm replacing both drives, the SCSI adapter, AND the power supply to make sure that this problem doesn't happen again.
