SOLVED Lost floppy in upgrade to 11.04

[hallergard]

Cannot mount floppy (sudo mount /media/floppy0) after upgrade from 10.10 to 11.04.
fstab is the same: dev/fd0 /media/floppy0 auto rw,noauto,user,exec 0 0
Have tried changing auto to ext2,ext3,msdos,vfat with no luck. Help appreciated!

Re: Lost floppy in upgrade to 11.04

The drive designation for the floppy has most certainly changed from /dev/fd0 to /dev/sdx (where x is some letter). Open a console and run:

sudo blkid -c /dev/null

Look for the floppy drive and note the /dev/ designation and change your fstab entry accordingly.

Thanks Snowhog.
sudo blkid -c /dev/null only shows my mounted partitions, but not the floppy because I have not mounted it. Tried /dev/sdc which seems to be the only one that exists in /dev/ but it did not work. Other ideas please.

Other ideas please.

sudo modprobe floppy

Re: Lost floppy in upgrade to 11.04

Is the floppy 'internal' or USB? If USB, connect it, and reboot. Then open a console and type:

sudo fdisk -l

Again, note the /dev/sdx designation of the floppy drive.

Re: Lost floppy in upgrade to 11.04

Thank you guys, but none of your suggestions work for me. The floppy is "internal".

Re: Lost floppy in upgrade to 11.04

Does lsmod show the floppy module loaded? As I recall, the floppy kernel module was disabled from automatically loading some years ago, so you have to load it manually.

Re: Lost floppy in upgrade to 11.04

lsmod shows this: floppy 74120 0 Does that mean loaded?

Does block mean that it is blocked??

Re: Lost floppy in upgrade to 11.04

Insert a floppy diskette. Open a console and type:

sudo fdisk -l

Copy and paste the output in your reply.
While still in the console, type:

sudo blkid -c /dev/null

Copy and paste the ouput in your reply,

Re: Lost floppy in upgrade to 11.04

Decided to try to format a floppy: mke2fs /dev/fd0
It worked! Decided to try to mount it: /mount /media/floppy -a
It worked! Decided to copy a file to the floppy - It worked!
While still mounted I tried blkid and fdisk -s - no sign of the floppy.

Why did it not work before?? Tried various floppies before, mostly fat
but some were ext2. Now I try mounting these: Cannot unmount
the floppy. ls /media/floppy shows the same file as above, despite
a different floppy and different file systems. Strange.

Re: Lost floppy in upgrade to 11.04

Turned out that the file was never copied to the floppy, but to /media/floppy on the hard disk. But the formatting seemed very genuine. Something has changed in this respect with the newer kernels.

Re: Lost floppy in upgrade to 11.04

Found the solution! Change in /etc/fstab from "/dev/fd0" to "/dev/fd0u1440" (the only type I use)

[Snowhog]

Re: SOLVED Lost floppy in upgrade to 11.04

How weird. Your mounted floppy drive is actually gets identified as /dev/fd0u1440 - really?

[hallergard]

Re: SOLVED Lost floppy in upgrade to 11.04

Yes
