Re: mounting floppy with fs auto doest recognize vfat
I don't know why, but it seems that the module vfat is not loaded automatically when invoking the mount command. If you manually load vfat before mounting, "auto" will work. The first workaround is to add "vfat" to /etc/modules Micha Feigin a écrit : When I try to mount a floppy with file system marked as auto in fstab it does recognize vfat file system (disks from windows), I have to specify vfat explicitly.

Do you mean, "can you get another msdos-formatted floppy"? You can do
this my simply formatting any floppy as 'msdos' format.

Unix won't put a filesystem on a disk unless you tell it to
('man mkfs'). If you mount it as "msdos" then it is treated as msdos.
It is read and written to using the msdos format. The same goes for
"vfat", "ext2", "minix", etc. Note the difference between "msdos" and
"vfat" -- the former has only 8.3 filenames and the latter only works
with win32 systems (ie not DOS or Win3.1). There is a little
problem/annoyance though. By default if you use the 'auto' option,
msdos is found even when you have a vfat disk. This is totally
functional, aside from the filename limitations. To change the order
in which mount tries filesystems with the type "auto" create
/etc/filesystems with the following contents (adjust to suite taste) :
--
ext2
vfat
msdos
iso9660
--
(you don't need to list every filesystem type, just the ones you want
to control the order of).

If you can't read the msdos/vfat disk on a MS system, then it means
the filesystem is destroyed. Your only option now is to reformat the
disk and use it as a new one.

What I like to do is create a file named " floppy not mounted" in /floppy so that if I do 'ls /floppy' without the floppy mounted I see that "message". You can also make /floppy non-writable in which case you'll get errors if you try to copy data to it before you have mounted the floppy disk. -D -- If your life is a hard drive, Christ can be your backup.

Unlike the DOS world, Unix in general, and Linux in particular, do not guarantee that data will be written to disk immediately after the in-memory copy of the disk blocks have been updated. Unixes, in general, cache such info, and typically write out to media (floppy disks, hard drives, etc) only when its efficient to do so. Thus, when you make drastic changes to the contents of a floppy disk, the in-memory copy of those disk blocks gets updated, and this happens quite fast. However, unless this copy is written out to the floppy itself, the changes will not be permanent. There is a standard way that Unixes support to force the write to media. This is called the 'sync' command. If you had done 'sync' after changing the contents of your floppy, you would have seen that your system was writing to the floppy - which does take a significant amount of time. Given the symptoms you describe, I would guess that you didnt do a 'sync' before you popped the floppy disk, and thus your backups were never written to floppy before you popped out the drive.

This floppy is formatted ext2 filesystem and when I try to mount it with the above command I receive the following message: debian:/home/dlm# mount -t ext2 /dev/fd0/floppy Usage: mount [-hV] mount -a [-nfFrsvw] [-t vfstypes] mount [-nfrsvw] [-o options] special | node mount [-nfrsvw] [-t vfstype] [-o options] special node A special device can be indicated by -L label or -U uuid . Here's the line in my fstab file for /dev/fd0: /dev/fd0/floppy autodefaults,user,noauto0 0 I am able to mount other floppies, although I'm wondering if maybe I might have trashed the disk by removing it before unmounting it or something?? Well, thanks for your time and assistance cheers dale

Add to /etc/fstab:
/dev/fd0 /floppy vfat defaults,noauto,rw,user,unhide 0 0
Then:
$ mount /floppy
should be sufficient. Also there's the "auto" type, which need a file
named /etc/filesystems with a list of filesystem types to try.

In the block devices, you need a line that starts with 2 (that's the same 2 you see when you do "ls -l /dev/fd0"). If you've recompiled your kernel recently, you probably forgot to include floppy disk support. Just do "make config" again, and confirm everything with Enter except answer "y" or "m" to the question about floppy disks. Then recompile (make dep; make clean; ...). (The option is called BLK_DEV_FD or "Normal floppy disk support".) Alternatively, if you did answer "m", check that the module is being loaded.

I thought I saw you post the output from cat /proc/devices and it only had one line, "3 ide0", which means you have no floppy support in your kernel. This would have showed up as "2 fd".
