A couple of weeks ago while I was backing up my Everex 20D drive, I came up
with five different bad blocks.  I ran Mr. Fixit in Bad Block Lockout mode,
which placed the bad blocks in a BAD.BLOCKS file in the root directory, and
reallocated the damaged files new blocks to replace the bad ones.  I had to
recopy the files from floppy back to the hard drive, but otherwise the
problem was fixed very quickly and easily with Mr. Fixit.  Well...perhaps not
*very* quickly...the Bad Block Lockout mode had to read the entire drive of
40000 blocks.
