On modern disks you generally cannot do a lowlevel format (like in the old MFM & RLL days) although many disks will accept the command but will do absolutly nothing, well some will do a rescan for bad blocks.. Now if you want to get rid of "bad sectors" you should simply do a dd if=/dev/zero of=/dev/adX bs=1m and the disks *should* rewrite the sectors and remap them if they are really bad... -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
