Hi there!

I just tried to format some 1.2 Meg, high density disks in my
360K drive (as 360K), and I got the following error message:

	Invalid media or Track 0 bad - disk unusable

Now, I know that I can't format 360K disks to 1.2 Meg in a
1.2 Meg drive, but why can't I format 1.2 Meg disks to 360K
in a 360K drive?  I thought that "blank" disks are just that
-- blank.  They can be reformatted as long as the density is
"thick" enought, right?

BTW, I'm using DOS version 3.1, and the disks have been
previously formatted to 1.2 Meg in 1.2 Meg drives.
