Hello, I hopy you can give me an advice on how to use packet writing with DVD+RWs. I patched my 2.6.3 for packet writing using a Benq DW800A connected via USB and writing to CDRWs seems to work. If I try to setup a DVD+RW with cdrwtool -d /dev/cdrom -q, however, I get the following error:
1216KB internal buffer setting write speed to 12x Settings for /dev/cdrom: Fixed packets, size 32 Mode-2 disc
I'm going to do a quick setup of /dev/cdrom. The disc is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now. ENTER to continue.
Initiating quick disc blank wait_cmd: Input/output error Command failed: a1 01 00 00 00 00 00 00 00 00 00 00 - sense 05.30.00 blank disc: Illegal seek
Any idea what's going wrong?
I think you would need to port these patches to 2.6 to make it work: http://w1.894.telia.com/~u89404340/patches/packet/2.4/extra/2.4.23/
As a side effect, I found the packet driver realibly oopsing when trying cdrwtool -d /dev/cdrom -g

I think this bug is fixed by the 2.6.4-rc2 patch: http://w1.894.telia.com/~u89404340/patches/packet/2.6/packet-2.6.4-rc2.patch... -- Peter Osterlund - petero2@telia.com http://w1.894.telia.com/~u89404340
