[RELEASE] DVD+RW Support for 2.6.6
Hi guys, Sorry for the long time its taken me to spin the patch for 2.6.6, been a little busy. Anyway DVD+RW support is now available for 2.6.6, patch is available from the downloads section on www.lbsd.net If possible, i would like to know success stories (make & model) so I can list supported hardware as i've heard there are a few drives that don't work so cool. Regards Nigel Kukard
Thanks for the patch Nigel. Unfortunately, DVD+RW isn't working for me. This is what i tried (pktcdvd0 is my CDRW, btw): pktsetup /dev/pktcdvd1 /dev/hdd mount /dev/pktcdvd1 /dvdrw -t udf -o rw,noatime The mount command resulted in: /dev/pktcdvd1: can't read superblock. dmesg reveals: pktcdvd: Unknown disc. No track? pktcdvd: pktcdvd1 failed probe The media mounts fine with: mount /dev/hdd /dvd -t udf -o ro and I can view and copy the files already written to it. The media was formatted, the udf file system created and the files written with the same drive, but with the system booted from a different partition that has a 2.4.26 kernel patched for packet writing and DVD+RW. On this setup, /dev/hdd becomes /dev/sr1 through ide-scsi, so I've tried the 2.6.6 setup with scsi emulation but had exactly the same outcome. The drive is an Optorite DD0203. Any advice you can give would be greatly appreciated Chris On Thursday 27 May 2004 06:42, Nigel Kukard wrote:

It works for me using an Iomega Super DVD 8x USB drive and kernel 2.6.7. It's *very* slow though. Copying 120MB of mp3 files to a 4X DVD+RW took approximately 8 minutes. (I used an ext2 filesystem on the DVD.) During that time, the drive light flashes mostly green with occational red flashes. I guess this means that the drive firmware is doing read-modify-write cycles internally, but handles it in a far from optimal way. Next, I'll try porting the dvd-rw-packet patch to 2.6. Maybe letting the kernel handle the read-modify-write cycles will improve performance. -- Peter Osterlund - petero2@telia.com http://w1.894.telia.com/~u89404340

OK, with the dvd-rw-packet patch, the same test finishes in 1 minute and 50 seconds. I have uploaded patches for 2.6.7 here: http://w1.894.telia.com/~u89404340/patches/packet/2.6/extra/2.6.7/ -- Peter Osterlund - petero2@telia.com http://w1.894.telia.com/~u89404340
