- What you do is to take a track and sector editor, copy an "empty" directory
- sector (ie: create at least 8 files on a blank disk and then scratch them) to
- all the sectors in track 19 or 17, then modify track 18, sector 0 the first two
- bytes to point to your first sector in track 17, then modify the first two
- bytes of that sector to point to the next track 17 sector etc. Once you're
- finished with the track 17 sectors modify the last track 17 sector to point to
- the old track 18, sector 1.
-
- I forget offhand which DOS commands are now allowed but be extremely careful
- using a disk such as this. *smiles* I imagine you would not want to validate
- the disk either.

- their endless search for "one more feature". Their irritating
- unwillingness to learn how to do things my way has usually led to my
- doing things their way; most of the time, they have been right.
