- Earlier, I had posted a series of steps for bad144 bad sector mapping.
- Unfortunately, the problem with bad144 handling is even worse than I realized.
- The problem appears to be when a write is attempted on a bad sector that has
- been mapped out. So for now, the steps I posted DO NOT work. My advice would
- be to re-low-level format the hard drive and use bad sector sparing if your
- hard drive controller supports it and you have the time. Otherwise, a bad
- sector in the inode list (or any other critical file system area) can be nasty.
-
- Also, a couple of people have experienced problems with corrupted bad
- sector file, which I also ran into. My solution was to write an /etc/disktab
- entry and completely re-disklabel the disk. Using bad144 after that didn't
- cause any more bad-sector corruptions. But again, bad144 handling really
- doesn't work right now anyway.
