Huh - your floppy is working?
Mine does not (with 2.4.0pre10-test1 that is):
[Marvin:~#] dd if=/dev/fd0 |od -c |more 2880+0 records in 2880+0 records out 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 5500000 [Marvin:~#]
This floppy currently holds my MILO image so output is definitively wrong :-) I also saw pure random data (fragments from libc etc.) on different runs.
