So if I understand you correctly; the floppy is mounted, it's just that konqueror can't see it.
Could you test this more thoroughly from the commandline (konsole or whatever you use)
check if the floppy is really mounted:
try copying a test file to floppy:
Code:
cp /path/to/test/file /mnt/floppy
to make sure your changes are written away:
list the contents of the floppy and check if the test file is there:
Let me know if this works. If it does it's a konqueror problem, if it doesn't we'll have to look further..
