What do you exactly mean by "floppy drive is lost" ?

Did You mount the floppy in order to see it ?
(sudo mount /media/floppy , the floppy should be /dev/fd0)

By the way you should have an entry in /etc/fstab that shows the
floppy device and it's mount point.

Is it just that the distro doesn't see the floppy device at all ?
(Check output of sudo lshw, do you see a floppy controller ?)

In that case is may just that you have to find out about what driver
should be loaded for your hardware.

We need more info. I had a thinkpad with a floppy in a bay, I could
switch between the CD reader and the floppy. On all machines I had
with a floppy : it worked. So I'm kind of puzzled why yours wouldn't ???
