floppy always read only

Asked by fabrom

All my floppies are read-only on 7.10 !

- floppy is not read-only locked

- /etc/fstab seems to be good :
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec 0 0

- users are members of the floppy group

but /etc/mtab show :
/dev/fd0 /media/floppy0 vfat ro,noexec,nosuid,nodev,user=fabrom 0 0

- formatting under Nautilus works but i can't create anything after mounting the formatted floppy !

- after mount :
lrwxrwxrwx 1 root root 7 2007-10-27 09:53 floppy -> floppy0
drwxr-xr-x 2 fabrom fabrom 7168 1970-01-01 01:00 floppy0

How to make floppy read-write for floppy group members ?

Try mounting the drive as root by hand to check:

mkdir /tmp/fdtest
sudo mount -t vfat -o rw /dev/fd0 /tmp/fdtest

If it is still read only you may have a BIOS configuration telling your drive must be read only, check your computer setup (usually pressing the Delete key during boot).
Or your drive may be broken and detecting all disks as read-only no matter in what position the switch on the disk is.

by hand, mounting as requested is ok : can write, can delete, ...

So it's not the floppy physical protection and it's not the bios settings (formatting works)

Works today (reboot or logout needed after users put in floppy group ?)

yes! When you add someone to a group that user must logon again for the effects.
