It seems to me that you might have tried to mount the floppy as thought it had a *nix filesystem on it.
What was the command you used?

Something I found from Linus' Homepage was
 
If you have an MSDOS floppy that you want to mount, insert it in the floppy drive and type mount -t msdos /dev/fd0 /mnt/floppy. What this line does should be quite clear: 'mount' is the mount command, '-t msdos' tells mount that it's going to mount an MSDOS file system, '/dev/fd0' is the device (the floppy drive, what you would call A: under MSDOS), and '/mnt/floppy' is the mount point (which you change to some other empty directory, if you want to). After you've mounted the floppy, just cd to /mnt/floppy, and use 'ls' to see what's on it. You can then manipulate the files on the floppy, just as if they were native Linux files. To unmount the floppy, you type umount /mnt/floppy.

Don't forget to unmount a device before you eject it! Failure to do so may corrupt the file system on the disk. You can't be sure that everything has been written to the disk, until you've successfully unmounted it. When you unmount a floppy, you make sure that the file system on it doesn't get corrupted when you eject it. Don't forget this.

If you have a non-standard format try substituting the other options as mentioned earlier.

Hope this helps
