I have a 80 Meg disk with about 240 kb of bad sectors
scattered all over the disc. I can install 386BSD on the
hard disk and it boots just fine (no messages about bad
sectors). When it comes to extracting the bin01.* files
after copying them on my machine, it says that there are
several corrupted files. However, I have successfully read
and extracted the bin01.* files on an other machine having
a disc without any bad sectors, thus the bin01.* files I have are
correct. Is my problem related to the bad sectors on the hd??

I could not use bad144, because no messages like
"wd0: hard read error writing fsbn ..........."
occured during the installation procedure.

I heard about a new wd.c driver which is supposed to do bad sector
mapping in a better way than the original wd.c. Is there somewhere
a compiled kernel with this new wd.c driver out in netland?

Any comments are appreciated.
