The secondary purpose is: Note that I strongly recommend not putting any important data on a drive that has shown to have defective sectors(*). You never know when the next sector is going to go. We're replacing a drive that has remapped 13 sectors or something like that, and it's now given us the first IO errors, so it's going towards the bin. Roger. (*) If you're sure that something external which can be prevented in the future caused the bad sectors, then fine. But if a drive is developing bad sectors all by itself, the future might bring remapped sectors until the slack remap space runs out, or one day a sector containing important data goes bad.... -- ** R.E.Wolff@BitWizard.nl ** http://www.BitWizard.nl/ ** +31-15-2600998 ** *-- BitWizard writes Linux device drivers for any device you may have! --* **** "Linux is like a wigwam - no windows, no gates, apache inside!" ****
