By default, Ubuntu configures the floppy diskette drive (/dev/fd0) so that
- Anyone can mount it, but only the user who mounted it can unmount it
- Only the user who mounted it can write to it
This document explains how to configure Linux so that anyone can mount, unmount, or write to a floppy diskette without restriction, like some other popular operating systems.
Change the floppy diskette drive entry in /etc/fstab file
sudo nano --nowrap /etc/fstab
from:
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
to
/dev/fd0 /media/floppy0 auto rw,users,noauto,fmask=111,dmask=000 0 0
Note that user is changed to users and the permission masks are specified. fmask=111 means for regular files, deny execute permission to all (chmod a-x) and allow all other permissions. dmask=000 means for directories, do not deny any permission.
man fstab and man mount and man chmod for more information.
