Hi guys,
I'm very new to the world of linux, and already i've had my first casualty! I THINK i may have mounted my A: then forgot to unmount it before i shutdown the system.
Now I can't access my removable floppy, ie if i double-click on it or type "a:" it does not read it. The error I get is, "file system not found" or in DOS, the floppy is not formatted.
Is there anyway to reverse this and recover my data?
I'd appreciate your feedback.
Thanks.

In a shell prompt try this with a floppy disk in the drive:
$ mount /dev/fd0 to mount the disk.
$ umount /dev/fd0 to unmount the disk.
Thats a number zero not letter O.
If that don't work then try those commands as root and see what happens.

well this is the beauty of linux that if u forget to unmount a filesystem when u reboot linux automatically does that for u.so i dont think the problem is because u forgot to unmount it .
make sure u mount it again .
or if u are using X under KDE then just clicking of the floppy icon will mount it automatically.
make sure the floppy u have inserted is fine.
luv,
saurabh.

THANKS..
I think you are right about the mount not affecting my floppy disk in this way. I managed to do an "mdir" command on my a: and was able to open the disk (on my HOME box). However, when I tried to access this same disk on another linux box, I could not open it.
When I try to access the floppy disk in Win98/2000 I get this error:
C:\>a:
Data error (cyclic redundancy check).
....
Does linux make the floppy unuseable under other environments? This is the 2nd time this has happened to me.
Linux doesn't make the disk unuseable if you mount and unmount it correctly ;)
Normally if the floppy was formatted as a DOS/Windows disk, Linux can read it, but you might need to tell Linux what the format is by using the -t (type) option in the mount command: mount -t msdos /dev/fd0 /mnt/floppy or mount -t vfat /dev/fd0 /mnt/floppy.
If it was formatted under Linux, DOS/Windows won't be able to read the filesystem.
