Problem with fd

I am having trouble with mounting a floppy disk as a file system. when i
give the command

mount /dev/fd0 /fd

I get an error saying that the mount failed because “corrupted file
system detected”. I have formatted the floppy disk using the fdformat
utility, before trying to mount it. The Fsys.floppy is running when I
try it.

Another weird thing thats happening is that I am unable to kill the
Fsys.floppy process if I want to. It just wouldnt die with either kill
or slay commands.

I would appreciated a detailed explaination of this weird stuff thats
happening.

Thanks.

Do a dinit /dev/fd0.

Fdformat does a “low level” format but doesn’t
create the filesystem.

Try Dosfys after Fsys.floppy is running.

Even with the Dosfsys, the same problem pertains.

What happened to the “dinit” dommand after the fdformat command??

Make sure there is NOT a disk in the drive while you’re doing the mount
command. You cannot mount the drive with a disk in there.

Hmmm… I guess it’s not true… I usually mount floppy with a disk in
it. But the disk need to be fdformat’ed and dinit’ed before doing it,
or else mount will warn that there’s a corrupted filesystem.
And it’s even better to mount with a disk in it, since it’ll run
quicklier! (mount won’t wait for disk check timeout)

No. You should have a disk in there when you mount (and you should unmount
before you take it out).

To use floppies:

Fsys.floppy (and of course Fsys) must be running.
Fsys.floppy &

The disk must be formatted or you can format it with fdformat. Assuming this
is the first floppy drive (fd0):
fdformat /dev/fd0

The disk must have a qnx-filesystem, you make this with dinit
dinit /dev/fd0

Mount the disk into the filetree, you specify what you want the subdirectoy
to be known as, I prefer /fd:
mount /dev/fd0 /fd

When done, unmount it:
umount /dev/fd0


However, if you want to use DOS-formatted floppies:

Not that the DOS command format formats the floppy and makes a dos
filesystem on it. I don’t think you can dos-format a floppy on a QNX-system
(maybe you can do a fdformat and dump a precopied image of a dos-formatted
floppy?)

Instead of mounting you start the dos file system driver.
Dosfsys -L &

The -L mean Dosfsys will support long filenames, but only for reading
according to the manual for QNX 4.25 (are there newer versions that can?)

Now the drives will show up under /dos as a, b and so on, so the first
floppy is /dos/a.

The error message “Corrupted filesystem detected” is bad and should have
been replaced. It means “Could not detect a valid QNX-filesystem”, and you
get it if you try ti mount an unformatted or unititialized diskette or if
it is a DOS-diskette.
