1. Disk copiers (other than DCFORMAT) usually do not like extended 
   formatted disks.  If anything, you must copy the disks in 'protected'
   mode.

2. There are at least two different kinds of drives out there.  A friend
   of mine uses extended a lot and when we passed along disks of PD stuff
   for my BBS, sometimes my drive couldn't read his disks.  So, WARNING:
   if you use extended format disks, use them only for personal use.

3. Disk manufacturers _do not_ test the disk beyond eighty tracks.  As many
   people know, you can use single-sided disks in double-sided format and
   you usually have no problems.  I _have_ had problems doing that (on my
   old 800 with the clunky 810 drive and on my ST).  So the extended
   formats are the same-  not guaranteed to work.  So, CAUTION: do not
   use extended format disks for important data.

4. Neil Harris doesn't recommend using non-standard formats.  SO THERE!!
   (I have mail from him somewhere that says this...)
