Hi,

To quote the IBM PC-DOS Manual for version 3.10, concerning FORMAT.COM:

/4 to format a double sided diskette in a high capcity drive. pg. 7-107

Which means that by entering the command 'FORMAT A: /4<cr>' you may
format a 360K diskette in a 1.2M disk drive.

The manual does mention that this technique is not 100% reliable, and that
some 360K disk drives may not be able to read the diskettes formatted in 
this fashion. I guess it has to do with drive calibration, as I have not
had any problems taking diskettes formatted in my AT to my Deskpro at home,
or to any other IBM PC.

Good Luck all....
