Event log has shown the following error a few times :: "The device, \Device\Harddisk0\D, has a bad block." I have tried to scan the drive and have found no errors. First, to confirm, which drive would that be? Second, which disk check utility should/would show that type of error. Third, any other suggestions or needs? Running: WinXP SP2 OS Hardware: 2 physical drives on IDE primary, 1 physical drive on SATA & 2 CD/DVD drives on IDE secondary.
