IDK if you can do this or not. Say if you have a file that is 2.048 Gig and it is attached to a loopback device, say /dev/loop0,
losetup /dev/loop0 FILE_NAME,
And you tried cdrwtool -d /dev/loop0 -q;
Now I have tried this and get errors. IDK if there's a way around this, a safety issue that is built in, or maybe I am not using the right program to format a "dvd".
Can you dvdformat a loopback device?
If you are trying to create the DVD file system, you want to use something like mkiso.
I've never used cdrwtool, but based on the name I would think it is used to send the commands to a disc burner to actually burn the disk - but it would need the data to burn, such as an iso file created by something like mkiso.
