Basically, you can't do that with format. Or, you can do it, but you
further risk your data.
What I did in similar situation is, I found out where the bad blocks
are (maybe the best source for this is the syslog), then I made two
partitions using fdisk, but I left the damaged part of the disk
unpartitioned, padded with, say, 50 megs before and after that part,
because I heard that bad blocks can propagate if the hard drive head
goes over those damaged sectors, so I guess it's the best if you keep
them isolated in unpartitioned space.
