I want to map out bad sectors on a disk.
I tried 'bad144 sd1' and here is an excerpt:

sn=509571, cn=11316, tn=59, sn=56
sn=1100276, cn=24436, tn=111, sn=101
sn=1145378, cn=25446, tn=50, sn=58
bad144: /dev/rsd1c: bad flag in bad-sector table
bad144: /dev/rsd1c: bad magic number
bad144: cyl/trk/sect out of range in existing entry: sn=682930, cn=15163, tn=119, sn=0
bad144: cyl/trk/sect out of range in existing entry: sn=1272565, cn=28265, tn=105, sn=115

Does this mean that the bad sector information on this disk is corrupt
and not useful?  Or does it mean that bad144 only applies to wd
devices? Or does it mean something else altogether?
