Using ide-scsi without reboot
by Johnathan Hicks 03 Sep '01

03 Sep '01

I have an IDE CD-RW which I use with the ide-scsi stuff. Now given that the ide-scsi only picks up the device when it is stated so in the line of kernel parameters. Now supposing that I have ide-scsi compiled as a module, but want to test out packet-cd on the ide interface. How can I make the kernel allow the ide driver to control the device without having to tweak lilo.confm run lilo, and reboot? Thanks. --John

2.4.7-pre7 + some things + ISDN
by koalasoft＠gmx.de 31 Aug '01

Hallo , 1st i've a problem, to understand the enumeration on packet-cd. I get the patch 0.0.2m, which says "grab kernel 2.4.6 or 2.4.7-pre7". Now i have original kernel 2.4.6, and after patching and compiling, uname says, i've kernel 2.4.7-pre7. Have i now to apply the other patch in the packet? (when trying, i get "chunk" messages) Can someone a little explain, how to understand this? 2nd, when patching my 2.4.6 to 2.4.7-pre7, i can't get my hisax-module for ISDN running. There are error-messages about a "declaration jiftime". OK, if i save my original-isdn-modules from 2.4.6 before compiling and then restore this to the modules-dir, my ISDN works; but i'm not really happy with such "tricks" :-). And at general: is there any time-plan, when packet-CD will be included in the kernel, or will it be a patch forever? Greetings--

CREATIVE DVD-RAM SDR-1216S
by James Leitch 30 Aug '01

30 Aug '01

Hi I have been following the packet writing project with a lot of interest. I have a Creative DVD-RAM type RAM1216S connected to an INITO INI-940 Scsi controller card. Everything goes to plan 1) I can see scsi0 created at boot time. 2) I can see sr0 cretaed at boot time. 3) I can mount a disk formatted by UDF under windows and can read from the disk. The problem is I cant write using a udf formatted disk. Here are the logs: Aug 29 02:08:41 dt-uk-jleitch2 kernel: sr0: scsi3-mmc drive: 0x/0x dvd-ram cd/rw xa/form2 cdda tray root@dt-uk-jleitch2:/home/jleitch > cdrwtool -d /dev/sr0 -q using device /dev/sr0 wait_cmd: Success Command failed: 5c 00 00 00 00 00 00 00 0c 00 00 00 -

a problem about the USB CDRW and Packet-cd
by Dino 23 Aug '01

23 Aug '01

hello ~~ i have a problem when i use the pakcet-cd with the USB-CDRW i use the packet 0.0.2o-pre1 and linux 2.4.7 , my cdrw is the iomega zipcd 650 USB CDRW , but my system is stop, and the cdrw is access the cd .at last , the system dead , but when i use the IDE CDRW ,everything is all right. i try not to execution the "pktsetup" , and direct using "mount /dev/pktcdvd0 /mnt/cdrw" , it ok , but it using the iso9660 cd format . when i type "pktsetup /dev/pktsetup/ /dev/scd0 " and i teardown the cdrw with type " pktsetup -d /dev/pktsetup " , the system is halt too. so , is any one test the packet-cd with the USB-cdrw?? i try to print the error code , the program stop at the "generic_packet()" function in the pktcdvd.c

Input/Ouput Error & cdrwtool
by Craig Bowlas 19 Aug '01

Hi, I have an Acer peripherals CDRW 6x4x32 drive and have been trying to get it to work with Packet-CD. When I run cdrwtool the programs offers to write a long track. After a good while (~30min maybe) the program terminates. The dialogue is as follows... -------------------------------------------------------------- using device /dev/hdb 1596KB internal buffer setting write speed to 12x Settings for /dev/hdb: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/hdb. 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. performing optimum power calibration for speed 12 Initiating quick disc blank Disc capacity is 275616 blocks (551232KB/538MB) Formatting track Writing UDF structures to disc 3600 (BST)/-60 wait_cmd: Input/output error Command failed: 2a 00 00 00 00 00 00 00 20 00 00 00 - sense 0a.00.00 Error writing packet 0 (ffffffff) --------------------------------------------------------------- I note that the speed is incorrectly reported, but this I believe is ok from other posts to this list. Also the buffer size is reported as 1.5MB when the drive is fitted with 2MB.

MachineOfTheMonth: Using your CD-RW drive as a UDF filesystem packet writer Part 2
by Fr�d�ric L. W. Meunier 19 Aug '01

19 Aug '01

Maybe you already noticed the story at Linux Today, but I'd like to know if you can really remove files. If yes, does it work efficiently ? "I tried to do too much too soon and realized that the packet writing process is kind of slow and inefficient, even when trying to delete stuff. I ended up ruining that disc too when I turned off my computer to stop a deletion process that would have taken an hour." And what about the media ? I just ordered 10 Acer to play with. "Unfortunately, I had some problems getting additional cd-rw discs to format. I tried about 5 more of them and none of them worked." http://linuxtoday.com/news_story.php3?ltsn=2001-08-18-005-20-OS-HW-SM http://machineofthemonth.org/articles/a77/index.html -- 0(a)pervalidus.{net, {dyndns.}org} Tel: 55-21-2717-2399 (Niter�i-RJ BR)

bugs in latest patch
by Matthew Gabeler-Lee 19 Aug '01

19 Aug '01

I managed to get the latest patch to apply to 2.4.6 (had to do a couple small bits manually), and when I booted I noticed something weird: The /dev/pktcdvd that devfs made magically appear was major 0, minor 97! Rummaging around in the code, I found that the line in drivers/block/pktcdvd.c which calls devfs_register has its parameters mixed about. It has as 3 of its parameters "0, DEVFS_FL_DEFAULT, PACKET_MAJOR" (sorry about minor errors in const names, don't have code to look at here). The parameters to devfs_register for those 3 are supposed to be in the order flags, major, minor, so the 0 needs to be moved to be after PACKET_MAJOR. Making that change made the devfs node appear correctly. Also, when built as a module, it seems to leak the /proc/drivers/pktcdvd directory node when unloaded, causing multiple of those nodes to appear if it gets loaded and unloaded repeatedly. -- -Matt Using words to describe magic is like using a screwdriver to cut roast beef. -- Tom Robbins
