I've recently aquired a Pioneer DVR-A03 DVD-RW drive. I would like to get this working with packet writing but according to the patch, it doesn't work for DVD-RW. Could someone let me know what is required to make it work and if the packet-writing patch is the best starting point. You first need to get the MMC specifications from http://www.t10.org/drafts.htm. It looks like there is a new 'MMC-4' version

In order to test writing to the drive, you should probably start with cdrwtool from the UDF package and see how much you have to change to make it work on your drive. You can also look at cdrecord to see some code that should be able to write to your drive already, but that is a lot harder to understand than cdrwtool. IIRC, DVD-RW drives can operate similarly to DVD-RAM drives (which are supported in the standard kernel), but need to be initialized differently. If that's true, you would be better off basing the kernel support on the scsi cdrom driver than the packet writing driver and have the added bonus of being able to use any file system, not just UDF. I just noticed there is already a driver for DVD+RW (not DVD-RW) on http://fy.chalmers.se/~appro/linux/DVD+RW/, which might also be helpful. Arnd <><
