Actually, DEBUG makes a pretty good (read "cheap") disk editor.  Check out the
commands "Load" and "Write" and you will find that you may specify particular
sectors or blocks of sectors to read/write into/from memory.  In memory, they
may be examined and modified with the "Display" and "Enter" commands.  In this
fashion, one may edit the actual directory area (just stuff a 0xE5 into the
first byte of the entry to eliminate, and update the on-disk copy. *BEWARE*,
though, this process is not for the inexperienced or faint-of-heart, patching
directories of live disks is not unlike open-heart surgery: one slip and
*SzzzzzxxxK!* (slicing motion of hand across throat).
