I can't write to my floppy KNX 3.4

I wonder if anyone can help me. I have finally got my CDRom & CDburner & even my DVDwriter
to work on knoppix 3.4 but I can read but I can't write to my floppy the error I get is: could not write to /floppy/filename.
I am using the 2.6.5 kernel
My fstab reads
# /etc/fstab: filesystem table.
#
# filesystem mountpoint type options dump pass
/dev/hda7 / ext3 defaults,errors=remount-ro 0 1
proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,user,noauto,exec,umask=022 0 0
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
I am using the 2.6.5 kernel with kernel-source installed
Can anyone help me to find out where I am going wrong. I have used most version since 3.2 and I have never had this problem before only with Morphix :)
