Linux-2.6.0
by Richard A Downing FBCS 30 Dec '04

30 Dec '04

I was about to update my kernel to the new stable 2.6.0, but notice Jens has added some changes since test11. Is there any reason to suppost the test11 patch wouldn't work? I guess this is just a way of saying 'Can we have a 2.6.0 patch please Peter?' -- Richard A Downing FBCS http://www.freewebs.com/109bean/ Anyone sending unwanted advertising e-mail to this address will be charged $25 for network traffic and computing time.

pkt_get_disc_info in pktcdcd-2.6
by O.Sezer 30 Oct '04

30 Oct '04

Hi Peter: What was the problem made you "add code for sending generic packet commands without relying on cdrom_device_ops" as you noted in changelog for packet-2.5.44? My interest in this is that when I tried to backport some 2.6 cdrom changes/fixes for my personal 2.4-tree (especially the csets 1.1975 "cdrom get_last_written fixup", and on top of that, 1.2087 "cdrom signedness range fixes") pktcdvd broke. My primary suspect for this is the return changes in the cdrom_get_di function, hence the $SUBJECT; will investigate it more. But this change in kernel is far much later than your change in pktcdvd-2.5/2.6. So, can you explain? Regards, Ozkan Sezer

help to get packet writing working
by gm c 29 Oct '04

29 Oct '04

I tried a year ago to get packet writing working with no success and am trying again. I read the latest postings, patched kernel 2.4.27 with patch 2.4.27 and kernel 2.6.9 with patch 2.6.8-2. On 2.4.27 said yes to pw on cd/dvd and udf filesystems and yes to scsi emulation.On 2.6 no scsi emulation and yes to packet-writing. My first try was with k 2.6.9. pksetup /dev/pktcdvd0 /dev/hdc mount -t udf /dev/pktcdvd0 /cdrw I could mount and read a windows made udf disk but could not format (cdrwtool -d /dev/hdc -q ). Trying different solutions (with and without scsi) I can no longer find what it takes to mount and read the pre written disk. With k 2.4.27 I am unable to read or write. cdrecord -scanbus gives my writer on 0,1.0 pktsetup /dev/pktcdvd0 /dev/sr1 mount -t udf /dev/pktcdvd0 /cdrw or mount -t udf /dev/sr1 /cdrw produces errors- again no writing. cdrwtool -d /dev/sr1 -i or -q or cdrw -d /dev/pktcdvd0 -i produce errors. I am on debian unstable. My cdrw is Lite-on. Help please. I would like to get p-w working. mike __________________________________ Do you Yahoo!? Yahoo!

2.6.9 success
by Graham Vincent 28 Oct '04

28 Oct '04

Hello packet writers. Just built a 2.6.9 packet writing kernel for my Intel/FC2/HP DVD 300i machine and thought I'd let you know it works :-) So pleased with CD-RW I thought I would try some DVD+RW media as suggested in the packet-writing.txt file. Looking at method suggested using the pktcdvd driver I recommend that a mention to "dvd+rw-format /dev/hdc" be added above the pktsetup line for new dvd+rw media. Having got 4.7Gb of UDF filesystem mounted I copied the 2.6.9 source tree over to the dvd. For about 30 minutes I could get no response from the computer as data was transferred. When the lights stopped flashing I tried to umount the disk. This resulted in a further 45 minutes of activity on the dvd drive, this time with normal response to other commands. This seems rather slower than the 2822 kB/s write speed the logs are reporting for the drive. Great to have packet writing working on CDRW and DVD+RW - well done! Any suggestions on getting better response from the system during the writing and increasing the transfer speed would be welcomed. Regards, Graham -- Graham Vincent

device problem
by Remus Anca 27 Oct '04

hi. i'm new on this list and new in udf fs i've read all about udf and i did this: install kernel 2.6.8.1 apply packet-patch-2.6.8-2 put Y (not module M) on packet writing and Y to UDF fs compile and install without problems get udftools 10b3 patching with patch to suport all version of pktdriver (>=0.2.0) i've take a look in /dev/ and i already have pktcdvd, 0,1,2,3 but /usr/local/bin/pktsetup /dev/pktcdvd0 /dev/hdc it's not working open packet device: No such device or address what i missing? PS: i try the same for 2.6.9 but the same error thx

What the 'F'?

Hi, It's been bugging me for a while. I'm sure it's not wise to ask... but: "We put the F in packet writing" What is the 'F'? -- Thanks, M

Problems with 2.6.8.1/Debian unstable/LG-4160b
by Theo Cabrerizo Diem 24 Oct '04

24 Oct '04

Hi, I've build my kernel (vanilla 2.6.8.1 + packet-writing patch) and trying to use with a LG GSA-4160b DVD+/-RW drive. # modprobe -v pktcdvd insmod /lib/modules/2.6.8.1-dexter/kernel/drivers/block/pktcdvd.ko # lsmod | grep pkt pktcdvd 32892 0 cdrom 41180 2 pktcdvd,ide_cd # ls -l /dev/pktcdvd* brw-rw---- 1 root cdrom 97, 0 Oct 23 13:46 /dev/pktcdvd0 brw-rw---- 1 root cdrom 97, 1 Oct 23 13:46 /dev/pktcdvd1 brw-rw---- 1 root cdrom 97, 2 Oct 23 13:46 /dev/pktcdvd2 brw-rw---- 1 root cdrom 97, 3 Oct 23 13:46 /dev/pktcdvd3 # pktsetup /dev/pktcdvd0 /dev/hdc open packet device: No such device or address same problem happens with 2.6.9-mm1. Both cases using DVD+RW media. Any idea, even how to debug this ? Thanks. -- Theo Cabrerizo Diem <diem(a)carpediem.sh>

problem formatting disc with cdrwtool
by Konstantin A. Lepikhov 23 Oct '04

23 Oct '04

Hi! According Documentation/packet-writing.txt disc must be formatted with command "cdrwtool -d /dev/sr0 -q" but it failed with following output: [root@lks /]# cdrwtool -d /dev/sr0 -q using device /dev/sr0 1314KB internal buffer setting write speed to 12x Settings for /dev/sr0: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/sr0.

Hi Peter, will there be a patch for 2.6.9 soon, or can the 2.6.8-2 patch be used safely (it applies without rejects)? Regards, Ingo

packet writing and QSI SBW-241
by Matteo Croce 21 Oct '04

21 Oct '04

Hi all, i have a Compaq Presario 2510EA laptop, with a QSI SBW-241 combo drive and a 2.6.9 kernel without scsi emulation # hdparm -i /dev/hdc |fgrep Model Model=QSI CD-RW/DVD-ROM SBW-241, FwRev=VY02, SerialNo= This drive is know to work badly under linux, expecially with CD-RW media (it can't erase CD-RW under linux, but it can write them), try to search with google 'QSI SBW-241 linux' I've installed the Debian package udftools (1.0.0b3-5) that includes the Peter Osterlund's patch but i can't format the CD-RW. I get this: # cdrwtool -d /dev/hdc -q using device /dev/hdc 1568KB internal buffer setting write speed to 12x Settings for /dev/hdc: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/hdc.

I discovered now that i can erase CD-RWs with cdrecord with the -immed flag, from the cdrecord manpage: -immed Tell cdrecord to set the SCSI IMMED flag in certain commands (load/eject/blank/close_track/close_session). This can be useful on broken systems with ATAPI harddisk and CD/DVD writer on the same bus or with SCSI systems that don't use disconnect/reconnect. These systems will freeze while blanking or fixating a CD/DVD or while a DVD writer is filling up a session to the minimum amount (approx. 800 MB). Setting the -immed flag will request the command to return immediately while the operation proceeds in background, making the bus usable for the other devices and avoiding the system freeze. This is an experimental feature which may work or not, depending on the model of the CD/DVD writer. A correct solution would be to set up a correct cabling but there seem to be notebooks around that have been set up the wrong way by the manufacturer. As it is impossible to fix this problem in notebooks, the -immed option has been added. This issue is related to many laptops, (SONY, HP, Compaq, Acer, etc..) since they use all this stupid drive. Can the cdrwtool have such a function, to allow formatting CD-RWs with these drives? P.S. i tried also upgrading the firmware... nothing to do Regards Matteo Croce -- .""`.
