That won't fix it either.  The problem is in the root directory on
the floppy disk, more likely than not.  You need to fix the floppy
diskette before that directory will ever be changed - mounting the
floppy puts the mounted-on directory underneath the root directory
on the floppy itself.  So, you need to chmod the directory =after=
mounting, not before.

As for changing the device, that only grants you access to the
device.  Once the floppy has been mounted, the permissions on the
filesystem control access.  Changing the modes on the device does
nothing at all.
