>Description:
After I mounted a msdos floppy on /mnt, read a file from it, and wrote another file to it, I tried to umount it, but I got the following error:
bash-2.05# umount /mnt
umount: /mnt: not currently mounted
I typed 'mount', and saw:
bash-2.05# mount
/dev/ad0s1a on / (ufs, NFS exported, local)
on F (msdos, mounted by news)
...
In addition, df -h output was:
bash-2.05# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 3.9G 2.1G 1.4G 60% /
1.4M 210K 1.2M 15% F
...
I mounted this diskette using the following command:
mount -t msdos /dev/fd0 /mnt
>How-To-Repeat:
I'm not sure whether I can reproduce the problem, but it was caused after typing the following command:
mount -t msdos /dev/fd0 /mnt, reading a 120kb file from the diskette, and writing 80kb file on it.
