Please use lines that are less than 72 (or at worst 80) characters long.

The width of the track on 1.2M 5.25" floppies is much narrower than the
width of the track on 360K floppies.  Hence, you may have problems with
noise if you format a disk on a high density drive, and then try to use
it in the future on a low density drive.  Likewise, if you write a file
with a high density drive, you may experience noise problems reading it
on a low density drive.  Note that the key word is MAY.   Note I always
mean formatting in the low density format, even on high density drives.

The newer technology is UPWARD compatible, but not necessarily DOWNWARD
compatible.  Hope that helps.
