I need to wipe some SCSI disks to DOD spec and I would like to use Tru64 to
do it. I believe the spec wants the disk to be wipe three times, once with
zeros, once with ones, and then once with a random pattern. The zero's I was
going to use /dev/zero and for the random I could use /dev/random by using
dd to copy to the disk.
Am I right that scsi has a pool of bad blocks that get allocated
automatically when they detect an error, if so my question is how do I
insure that I am erasing these bad blocks? If I use dd to copy a pattern to
the raw disk does it also write to these bad blocks, if not is there a
utility like scu or something similar that will write to them.
I know there are utilities out there that can boot into dos and wipe drives,
but I would like to use Tru64 if possible.
Thanks,
