Re: Debian & UDFS

If you check your dmesg you will see udffs complain that the device is 
not writable, and that it is falling back to read only mode.  This may 
be because your drive is not standards compliant, and will not accept 
single sector writes.  Using the pktcdvd driver might be able to work 
around that problem.  Install the udftools package and use pktsetup to 
bind /dev/pktcdvd/0 to /dev/scd0 and then try to mount /dev/pktcdvd/0.
