Hi, I can make packet-writing work. My system: 400MHz AMD K6-2, 128MB RAM Kernel 2.4.18-xfs, all Partitions XFS, IDE Harddisk WD 20GB Adaptec AHA1542C HP 1533A DDS3 Yamaha CDR4416S What I did: 1: patching a 2.4.18 kernel with the patch from http://w1.894.telia.com/~u89404340/patches/packet/packet-2.4.19-pre2.patch.… 2: After installing the new kernel, I formatted a CD sucessfully 3: pktsetup /dev/pktcdvd0 /dev/sr0 - no errors, see my /var/log/messages 4. mount /dev/pktcdvd0 /mnt -t udf -o rw,noatime, no errors 5. dir /mnt - bang, process stopped.

I'm getting the exact same error as the original poster was. I'm using packet-2.4.19-pre2 and udftools-1.0.0b2.

New pktcdvd version available
by Peter Osterlund 20 Mar '02

20 Mar '02

Hi! I have uploaded a new version of the packet writing driver here: http://w1.894.telia.com/~u89404340/patches/packet/packet-2.4.19-pre2.patch.… This patch was generated from kernel 2.4.19-pre2, but should work also with kernel 2.4.18. (and probably 2.4.17 too.) The interesting change in this version is that I have changed the way mixing of read and write requests is handled. The driver now inserts a "synchronize cache" command before the first read command following a write command. This has three advantages: 1. The hack in scsi_lib.c to retry failed read commands caused by the device not being ready is no longer needed. 2. Some drives report "command sequence error" if you try to send them a read command before the previous write command is finished. Those drives didn't work before, but I hope they do work with the new version. 3. IDE drives that previously only worked with ide-scsi emulation may now work also in native ide mode. I would like to receive feedback on this version, since I don't have the hardware necessary to provoke the problems mentioned in 2 and 3. -- Peter Osterlund - petero2(a)telia.com http://w1.894.telia.com/~u89404340

Problem with cdrwtool
by Chris Clayton 13 Mar '02

13 Mar '02

Hi, I have kernel 2.4.18 patched to 2.4.19-pre2 and packetcd 2.4.19-pre2. My CDRW drive is a Mitsumi CR-4802TE and udftools version is 1.0.0b2. When I try to format a cdrw disc, the following occurs: #cdrwtool -d /dev/hdc -t2 -q using device /dev/hdc setting speed to 2 1600kb internal buffer setting write speed to 2x setting for /dev/hdc Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/hdc...

Problem Formatting CDRW
by A. Lee 12 Mar '02

12 Mar '02

Hi. I am having problem formatting CDRW (I have a NEC NR7700A drive) and wonder if anyone here have the same experience before. The problem occurs since I upgraded my kernel from 2.4.7 to 2.4.18 (with packet-2.4.19-pre2.patch). When I try to format a disc with the command: cdrwtool -d /dev/scd0 -q -t 4 The 'quick disc blank' seems to work fine. But when it says "Formatting track", the LED on the CD-writer turns off and no more response. Later I tried again with the '-m' option and here's the result: $ cdrwtool -d /dev/scd0 -t 4 -m 275616 using device /dev/scd0 setting speed to 4 formatting 275616 blocks 1206KB internal buffer setting write speed to 4x wait_cmd: Invalid argument Command failed: 04 17 00 00 00 00 00 00 00 00 00 00 - sense 05.2c.00 format disc: Illegal seek This command returned after more than an hour, the LED on the writer is off at all time. Any help appreciated. --A. Lee
