Just a wild stab in the dark, but this usually happens to me when I've
accidentally put in a floppy which doesn't have a filesystem on it.
(done with the 'mkfs' command)
I'm still living with my MSDOS habits which make me assume that a floppy
is ready immediately after formatting. In Un*x, this is not true, you
have to mkfs before you can use it.
1) fdformat /dev/fd1
2) mkfs /dev/fd1 1440
3) mount /dev/fd1 /mnt
I don't know why, but occasionnaly I (accidentally, again) try and
mount my boot floppy...this also gives the error message.
This is just plain stupidity on my part since the boot floppy is not
meant to be mounted.
If you *HAVE* done the three steps detailed above, you might also want
to try substituting /dev/fd1H1440 instead of /dev/fd1
I had to do this once or twice for some reason...the auto-detecting stuff
wasn't working.
I hope I'm not assuming the wrong things here...
