Preferably a setup where you can lose more than one disk without losing the data. Note that, depending on where the bad sector is, when it gets remapped the extra seek necessary to read that logical address could slow the drive down substantially. Make sure your filesystem's root inode or something doesn't end up on top of it. Sometimes I miss the old drives where all this was handled by the OS and so you knew exactly what sector was bad and your filesystem could be told to just not use it. Made scanning for bad sectors more annoying, but deciding how bad the drive was rather easier. LMP
