this is on my domain controller, this is a HP raid5 array consisting of 4 72gb scsi disks. how can you get bad clusters on a raided drive? how can I know which physical drive is failing?

did I actually lose any data/get any data corruption?

I have backups of course, the problem if its hardware failure, and I am going to do migration to windows 2008 r2 from windows 2003, it will still take sometime to initiate things, buying a single replacement scsi might be viable but if I can't identify the drive and have to get 4 scsi drives and rebuild the array 1 disk at the time, it would be problematic not to mention prone to disaster.
