Bug Description

Trying to mount a floppy disk fails in Ubuntu.
It is a conventional floppy drive, with regular FAT disks.

Trying to mount a disk via the Places menu cause the drive to make noise but never actually mounts the disk. There is no error. This is the same thing that happens with mount in terminal, the disk makes noise and mount returns like it was successful, but it isn't actually mounted. Nothing is added to dmesg.

Using mtools' mdir a: works as expected; reads the disk, and displays the list of files.

pburt@magus:~$ dmesg | grep fd0
[ 0.340934] pci 0000:00:11.0: reg 18 io port: [0xfd00-0xfd07]
[ 0.906905] Floppy drive(s): fd0 is 1.44M
[ 82.510671] end_request: I/O error, dev fd0, sector 0

The I/O error line occurs during boot, before any disk was inserted. Nothing is written to dmesg when actually trying to use a disk.

Ubuntu 10.04

mount returns success, but doesn't actually mount. I can also dd an image to the disk without problems.

Still not working in 11.04.

Clicking on <Places><Floppy Drive> just turns on the floppy drive light for a moment, but doesn't seems to do anything else.

For some reason,

sudo mount /dev/fd0 /media/floppy0

doesn't work either, but I can

sudo mount /dev/fd0u1440 /media/floppy0

and a floppy0 icon appears on the desktop and I can click on that and Nautilus displays the files on it just fine but
read-only of course.

Clicking on <Places><Floppy Drive> still doesn't seems to do anything.

And, of course, I can't unmount the floppy0 icon from the desktop. It says:

umount: only root can unmount /dev/fd0u1440 from /media/floppy0

So I have to use

sudo umount /media/floppy0/

Addition:

sudo mount /dev/fd0 /media/floppy0

does not work,

sudo mount /dev/fd0u1440 /media/floppy0

does not work either, actually, it somehow managed to pull down the graphics driver (garbled screen). Has anyone faced this behaviour before?

Hello Customer

But what should you do if you can not afford the unique luxurious watches for all these wear?
What you see - is what you get!

I just received my PN-20 (Panerai Luminor GMT Automatic), and I have to say I'm really impressed. I have ordered from quite a few replica sites in the past, and I always ended up sending the watch back disappointed. I hope this makes it into your customer comments section. I would recommend this site to anyone. Very prompt delivery, great prices and wonderful quality.
Thanks for the fast response. You guys are great!
