Bad sector correction these days is done within the hard drive, the OS is not involved. If the OS used "empty" parts of the disc for redundant data storage, it would fill up. If there was one redundant copy of every sector, the drive would hold only half as much. People who to whom data integrity is that important are already using RAID arrays. What you describe would save you in the event of a bad sector, but wouldn't save you if the entire drive died. RAID can. Although you also want off-line backups in a separate location so that a fire can't wipe out the drive, the RAID array, and the backups all at once. -- Patrick
