I'll try checking the data cable of the floppy drive, however it's strange it did not happen with Ubuntu 7.04LTS nor does it happen with Windows XP - they both recognize correctly the floppy drive, correctly use it (writing/reading), and with both the led is not always on (only with activity, as it should be). I think there should be errors on drive activity, with a cable plugged backwards - there are no errors at all with the above OSes nor using the drive on 7.10 enabling the floppy module and manually mounting the device.
