State Changed From-To: open->feedback We need to know whether you can reproduce the problem. :-) Also, it would help if you could try to isolate the problem further. Specifically, is this a problem with mount_msdos or with floppy driver support. Either way, I have folks in mind to whom this PR could be assigned, but I'd need to know which. Please copy your feedback to <bug-followup@freebsd.org>, using the subject line of this message. Hi, As far as I recall it happend with an MSDOS FS. first I tried to unmount it using umount /mnt (it was mounted there), then using umount /dev/fd0 (the device), then umount -a -t msdos and finally umount -a - nothing helped. It was still mounted, and I was still able to access the floppy contents via /mnt. I can't seem to reproduce the problem, since it was after more than 30 days of uptime, so I don't remember the action I did before mounting the floppy, nor I've the original floppy anymore. Uri.

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 Fix: none known 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.
