I needed to make bootable floppy for graphic card BIOS reflash and
noticed that I can't fdformat floppy or even write to formatted one.
I can mount it -o rw, but when I try to write, write would fail.
Also, fdformat /dev/fd0 seems to be working, but just to the
point,where it verifies written and fails on track 0.
I have checked:
- floppies for write protection ( it was off )
- for dirt on heads- I have cleaned floppy thoroughly
- bad unit. Exchanged it with another, with exactly same result.
- bad floppy disk. Tried a few other, with same result. Same disks
formatted on another Windoze machine just fine.
- bad access flags on /dev/fd0. ( Access: (0660/brw-rw) Uid: ( 0/
root) Gid: ( 11/ floppy) )
Here is output of fdformat /dev/fd0:
LANG=en fdformat /dev/fd0
Double-sided, 80 tracks, 18 sec/track. Total capacity 1440 kB.
Formatting ... done
Verifying ... Problem reading cylinder 1, expected 18432, read 2048
and here is dmesg | tail:

Has anyone noticed anything remotely similar ?
I can recall being able to use floppy normally with older 2.6.27
kernels, but can't try this now...
