Well I do something like:
dd if=/dev/zero of=/mnt/resc2880.bin bs=512 count=5760
losetup /dev/loop1 /mnt/resc2880.bin
mkdosfs /dev/loop1 5760
and recieve:
mkdosfs: unable to get drive geometry for '/dev/loop1'

And instead recieve:
mkdosfs: no disk geometry for this file size defined

The info pages on mtools has a discussion of geometry, but only 1.44 and
below. There is no mention of the 2.88 format.
My interest is for a CD boot image, as the ET format will accept a 2.88
image. I only need to be able to build one.
On a side note: mkdosfs /dev/fd0u2880, gives errors about the device not
having enough sectors (it is actually a 1.44 drive) but seems like it
would have worked had the physical device been correct. This leads me to
suspect I just need the right values for the geometry of the physical
device in order to make mkdosfs happy.
Thanks,
