I have been trying to format a 3.5 inch DD floppy disk on some of
the machines at work and have been experiencing some difficulties.
The drives are high density drives, capable of writing 1.4 Meg..
The drives have been configured in config.sys as follows:
device=driver.sys /d:1 /f:7 /c /h:2 /s:9 /t:80 (for MS-DOS 3.3) and
device=driver.sys /d:1 /f:2 /c /h:2 /s:9 /t:80 (for MS-DOS 3.2)
The format program formats the DD floppies as 720K media, as I wanted;
however, the FATs are overlapping each other and the root directory.
CHKDSK complains, and when serviced with the /F option, the root
directory is garbaged.
I tried this on several machines, all using MS-DOS 3.2 and 3.3.
Using IBM DOS 3.2, the floppies format fine. I feel that this is a
MS-DOS format.com problem. Has anyone else experienced difficulties?

I have installed a 1.44 Mbyte 3.5 inch floppy drive on my XT clone. I ended
up modyfing my config.sys as follows using MSDOS 3.3:
drivparm=/d:1 /f:2 /h:2 /s:18 /t:80
When I format my b: drive (the 1.44 Mbyte 3.5 inch floppy) I then use
the following command:
format b: /n:18 /t:80
and I obtain a 1.44 Mbyte floppy that has no problems at all. For formatting
the 720 kbyte floppies I just type the command:
format b:
I hope this has been of some help. I found it took a little tinkering around
before I found this combo to work.
