And of course RAID has its own issues with RAID 6 really being required with today's large disks to protect against the separate-failure-during-rebuild case.

Without RAID, the operating system will have no idea the sector is corrupt - this is why I like ZFS's block checksumming, as you can get a list of files with corrupt blocks in order to restore from backup.
