OFYI: I have tried to format a floppy image with a VMware Player 5.0.2 using
FreeDOS 1.2-pre23 and I have observed the same issue as described for
VirtualBox.
If /q/u is used it becomes possible to format the image. I have also tried
to format using only /d. See below for the output produced. What surprises
me is that the format program from MSDOS 6.22 does not require options like
/u/q to format a floppy image on the same virtual machine. Issuing format a:
just does the job. For an user that is familiar to MSDOS but not familiar at
all to FreeDOS this deviation in program behavior may be confusing and the user
may have difficulties in formating an image.
Is this different behavior intentional? IMHO, if FreeDOS claims to be MSDOS
compatible, the deviation in behavior should be as less as possible. This is
not an issue for me personally. When I know that there is a difference in
program behavior I can act accordingly but it remains surprising that something
that I expected to be compatible is not always compatible conserning its
behavior.
