Re: hard- or software-raid?

This was with an Adaptec SCSI card. I'm not sure how it detected the error (may have been SMART related), but it told me there was an error so I swapped the drive and ran the diagnostic software over the drive. It came back clean so I reinstalled the drive and it failed again an hour or so later.

How exactly does it do this?

What brand of hardware RAID controller have you seen this with?  IDE or SCSI?
