Hello,
I still use floppy disks in certain contexts (i. e. for
certain small dedicated files I want to store away
separateley). Luckily, my two PCs still have "conventional"
floppy drives (/dev/fd0), configured like this:
,-----[ /bin/bash
]------------------------------------------------------------------
| ~ > grep floppy /etc/fstab
| /dev/fd0 /floppy vfat rw,user,noauto,async,noatime,noexec,fmask=137,dmask=037
0 0
| ~ >
`------------------------------------------------------------------------------------
and both my notebooks at least have USB floppy drives,
configured similarly with /dev/fd0 replaced by /dev/sdc:
,-----[ /bin/bash
]--------------------------------------------------------------
| ~ > grep floppy /etc/fstab
| /dev/sdc /floppy vfat user,noauto,async,noatime,noexec,fmask=137,dmask=037 0 0
| ~ >
`--------------------------------------------------------------------------------
All my computers are running the same software, a fairly up to
date Debian testing (squeeze).
Most of the access to the floppy drives is operated by special
bash scripts making extensive use of mount and umount.
So I was quite annoyed to find that presumably since the last
update of "mount" on 2010-06-24 (mount_2.17.2-3.1_i386.deb)
(I am not quite certain about the exact beginning!) these
scripts have been going wrong in a strange way:
After booting, everything is alright.
But after some time, "mount /floppy" simply does no longer do
what it is supposed to do. That is, it _seems_ to work
alright, i.e. the floppy drive apparently "reacts" producing
some noise, and the LEDs go on for a short time, but there is
no "effect" (contents of floppy not visible, floppy not
contained in /etc/mtab), although the exit code of the mount
command had been 0.
However, other programs like mtools and badblocks go on
working normally without any problems.
After rebooting the system, everything works fine again.
This phenomenon occurs regularly on all my systems, but
the time between booting and the first failure may vary.
I could not discover any rule whether it depends on what I am
doing in the meantime, but it seems that "doing nothing" is
innocuous. On the other hand, starting audacity seems to
have helped me twice in reproducing the problem; but this
may just be a coincidence.
There is no problem whatever with mounting other media.
I am joining a protocol of one of these occurrences:
During the whole of the following experiments, one and the
same floppy, containing a single file, was inserted into the
floppy drive.
Immediately after booting the computer, everything
worked as it should:
