You need to change the file /etc/mtools to access your 360K disk. There
sould be a line in your old '/etc/mtools' file to indicate a HD floppy disk:
A /dev/fd0h1200 12 80 2 15
where 80 is the number of cylinders per surface and 15 is the number of sectors
per track. You can read your 360k disk after you have changed 80 to 40 and
15 to 9 in you '/etc/mtools' file, but you cannot read your 1.2M disk again.
In order to solve the problem, you can add a new line for the drive:
X /dev/fd0d360 12 40 2 9
Now, you can access drive A for your 1.2M disk, and access drive X for your
360K disk.
