Hi, 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?
