Because all the bad sectors were in different positions the array worked fine until one of the disks failed. As I'm fond of saying at work, RAID is no substitute for regular, tested, backups. Regarding your problem - you can download the (very detailed) manuals for the 3Ware cards and their software from the 3Ware website. A quick scan suggests you need the "mediascan" command (P48). Newer controllers (9000 series) support scheduling of their equivalent. -- Rob | Oh my God! They killed init! You bastards!
