This is the first time we've tried the 3ware ATA RAID cards so I don't have
another 'known good' one. Usually we use SCSI RAID cards. If I were to replace
it I still wouldn't be able to guarantee that is was 'known good'. I may be
able to arrange a part replacement, just to test that theory, in any case.

Are you aware of any utilities which would be able to diagnose what you
describe? I guess what I'm asking is how did you determine that that was what
happened last time you saw these symtoms?
