SUMMARY
=======

The /1 switch of the FORMAT command should only be used on a 360-kilobyte (K)
disk drive. It should not be used on a 1.2-megabyte(MB) disk drive. If the /1
switch is used on a non-360K drive, FORMAT returns the following error message:

  Parameters not compatible. Format failure.

The purpose of the /1 switch is to format 160K and 180K disks. It cannot be used
in conjunction with the /4 switch.
