Well, I've tried almost everything I can think of to get bad144 to write
a bad sector table without corrupting the bad track table -- but it doesn't
seem to work for me. Perhaps someone could post the sequence of commands
which they used to correctly bad144 a disk partition.
I tried the following sequence:
o set partition type to 165
o boot dist.fs floppy
o # install
o shutdown
o boot fixit.fs floppy
o mount -u /dev/fd0a /
o disklabel -r -e /dev/wd0a
set 'flags: badsect'
o bad144 wd0 0
o shutdown
o boot hard disk
> error message: bad sector table corrupt
> jolitz banner -- uc regents -- device table
> probably around the fsck time -- system reboots
> the whole reboot sequence continually repeats
o boot fixit floppy
o disklabel -r -e /dev/wd0a
> error message: wd0: cannot find label (bad sector table corrupt)
o bad144 wd0 0
> error: can't write bad sector file [0-5]: read only filesystem
o boot dist.fs floppy
o # install -- no errors
o boot hard disk
> error message: bad sector table corrupt
> jolitz banner -- uc regents -- device table
> probably around the fsck time -- system reboots
> the whole reboot sequence continually repeats
o boot fixit.fs to go back to dos
o use diskmanager to reformat first track of 386bsd partition
o boot dist.fs -- and reinstall 386bsd normally
If anyone has any suggestions about how to do the bad sector table
initialize correctly please let me know.
Thanks, AJ
