One of my FreeBSD development boxes had a hernia last week when it lost
power while writing to disk. The drive wrote out garbage to a track.
I want to reformat the drive, (low level) but the bios doesn't have any
support to do this (In the past That is how I did this).
The machiine has 1 CD drive and no floppy..
anyone with any ideas as to how one can reformat a hard drive feel free to
lend me a clue..
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...
