We have a Vax 11/750 running 4.2 BSD. One of our CDC9772 drives has 
bad blocks in the replacement sector area -- We have reformatted the
drive once, but still keep having to put dummy entries in the
bad block table to get around the bad areas. Does anyone have a fix
to the hp driver to finally FIX this? Does 4.3 fix this problem? (fsck goes 
into an infinite loop -- revectoring ad infinitum when it hits a bad block).

Another problem we are having of late is that a particular inode keeps 
showing up as 'Partially allocated'. Fsck clears and reports the problem as 
having been fixed. We boot the machine and the machine crashes a short while
later with a 'dup inode' panic in 'ialloc()'. Does anyone know why this
problem keeps persisting?

Thanks for any help.
