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. Michel Vaillancourt wrote:

Hello, everyone. I am unable to write to my DVD+RW with UDFS. Here's what I am doing:

... I'm not entirely sure why it is not working. Any suggestions as to where I should start looking. I'd really like to make this work. :)
