I tried gfloppy on another machine, but this time without success.
I also tried fdformat many time with various densities, again without
success.
Finally, I tried superformat:-
# setfdprm /dev/fd0 hd
# superformat /dev/fd0 hd
Measuring drive 0's raw capacity
warmup cycle: 0 11168 11168
Fatal error while measuring raw capacity
0: 40
1: 80
2: 40
3: 00
4: 00
5: 01
6: 08
#
I also ran superformat under strace:-

------------------------------------------------------------------------
Thus it appears the superformat is also broken, so fdutils is involved after
all.
This under kernel 2.6.32-rc6. Has the floppy API been changed, perhaps?
