Uploading this now.

As far as I'm concerned, I consider this an aesthetic change. There is
still no guarantee that the total number of sectors is a multiple of
sectors per track. It just happens to work with the current values.

If you want to make this robust, you'll either have to explicitly
specify matched size/sectors/heads on the command line to mkfs.msdos or
disable the bogus mtools check like everyone else does when encountering
that error.

Seriously, searching for that error message in your favorite search
engine will give you pages upon pages of hits, all of them describing
how to turn it off.
