Summary: 

Jim wrote that his IBM PC/AT went wonka, put a very anti-social null in
place of the 'i' in the name of his /usr/bin directory name, and asked
if there was a better way to recover than to  reformat & recover.

Yep, but you ain'ta gonna like it.
ADB.
Yes, folks, just adb that raw hard disk device (unless you're lucky enough
to have a ported version of 'fsdb'...)  Using adb, you can do everything
from twiddle the superblock to fiddle the directory.  Only trouble is,
if you're not very comfortable with the file system structure, then this
could be more painful than the recovery.  (It isn't for me, but Altos diskette
drives are notoriously slow)  It really does help to know the block breakdown
scheme for the driver (i.e., blk => cyl/head/sector), although you can
still do it without that.

	This is *really* getting dirty,
