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.

lots of syslog error messages when writing to UDF DVDs
by Doug Holland 31 Mar '04

31 Mar '04

I'm running on an 650MHz Athlon, and the CD-RW drive in question is a generically rebranded Lite-On Combo LTC-48161H (16x DVD/48x read/48x CD-R/24x CD-RW combo drive.) I just compiled kernel 2.6.0, with the packet-writing patch (packet-2.6.1-rc1-2.patch.bz2) on a Debian unstable system. I followed the instructions in the hint file (http://cvs.linuxfromscratch.org/index.cgi/hints/Attic/cdrw-hint.txt?rev=1.3) to get it working, and it's working to an extent. The problem is that when I copy medium-large sized files (a few megabytes, such as an mp3,) the drive just keeps running & running, with the LED lit in amber (meaning it's writing). Running sync to get the drive to finish the job doesn't seem to do anything, and if I umount and remount the CD-RW, some of the files I tried to copy to it are missing. When I run dmesg, I get thousands of these error messages. ide-cd: write_intr decode_status bad hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 end_request: I/O error, dev hdc, sector 5736 ide-cd: write_intr decode_status bad hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 end_request: I/O error, dev hdc, sector 5744 ide-cd: write_intr decode_status bad hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 as well as UDF-fs DEBUG fs/udf/super.c:1005:udf_load_partdesc: Partition (0:0 type 1522) starts at physical 1408, block length 273920 UDF-fs DEBUG fs/udf/super.c:1338:udf_load_partition: Using anchor in block 256 UDF-fs DEBUG fs/udf/super.c:1571:udf_fill_super: Lastblock=0 UDF-fs DEBUG fs/udf/super.c:847:udf_find_fileset: Fileset at block=32, partition=0 UDF-fs DEBUG fs/udf/super.c:909:udf_load_fileset: Rootdir at block=64, partition=0 UDF-fs INFO UDF 0.9.7 (2002/11/15) Mounting volume 'LinuxUDF', timestamp 2004/01/13 02:33 (1e5c) UDF-fs DEBUG fs/udf/misc.c:286:udf_read_tagged: location mismatch block 4751, tag 0 != 3343 udf: udf_read_inode(ino 4751) failed !bh UDF-fs DEBUG fs/udf/misc.c:286:udf_read_tagged: location mismatch block 4751, tag 0 != 3343 udf: udf_read_inode(ino 4751) failed !bh UDF-fs DEBUG fs/udf/misc.c:286:udf_read_tagged: location mismatch block 4751, tag 0 != 3343 and Buffer I/O error on device pktcdvd0, logical block 31194 lost page write due to I/O error on pktcdvd0 Buffer I/O error on device pktcdvd0, logical block 31195 lost page write due to I/O error on pktcdvd0 Buffer I/O error on device pktcdvd0, logical block 31196 lost page write due to I/O error on pktcdvd0 Buffer I/O error on device pktcdvd0, logical block 31197 lost page write due to I/O error on pktcdvd0 Buffer I/O error on device pktcdvd0, logical block 31198 lost page write due to I/O error on pktcdvd0 Does anybody here have any ideas on how to get rid of these errors?

I would appreciate some help on how or what I need to do in order to compile cdmrw.c. I get tons of errors when using gcc -I and errors about functions because cdrom.h isn't found. Obviously not doing this correctly. Thank you in advance /Carl

Hi, Anyone know if there are patches available to use dvdmrw? I quite like the DVD-RAM disk i have, but want to also use dvd+rw disks... can't find any linux software though. :( -Nigel

DVD Packet writing
by Nigel Kukard 25 Jan '04

25 Jan '04

Hrmmm, 1. Would the CD MRW patch allow you to write a DVD RW disk like a CD RW disk? Or is the DVD code on the drive itself? 2. Is the only way to write a DVD with the packet writing patch? 3. Which patches should be applied to both packet write (using cdmrw for cd's) and DVD's? Thanks Nigel

mrw + packet writing + variable packet sizes
by Nigel Kukard 12 Jan '04

12 Jan '04

Hi guys, Is it possible to do packet writing of variable sizes? I've applied the mrw patch to my kernel as i found on the site, but the only way it seems I can create a usable disk is if i use pktsetup with the -q option. Is there a manual way to reserve a track & say format it with ext2 or so? also what exactly is mrw? :) Regards Nigel

WRITE error with 2.4.24
by Jens David 11 Jan '04

11 Jan '04

Hi, I am trying packet writing and UDF for the first time. Unfortunately it does not quiete seem to work. I am using a 2.4.24 kernel with the 2.4.23 packet writing patch. CDRW drive is: /dev/hdc: Model=UJDA740 DVD/CDRW, FwRev=1.00, SerialNo= Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=512kB, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 IORDY=yes, tPIO={min:180,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 *udma2 AdvancedPM=no Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3: 1 2 3 4 5 Formatting went flawlessly (albeit slowly) using cdrwtool -q. I associate the packet device using: pktsetup /dev/pktcdvd0 /dev/cdrom where /dev/cdrom is /dev/scsi/host0/bus0/target0/lun0/cd (obviouly using idescsi translation). Using pktsetup /dev/pktcdvd0 /dev/hdc it does not work at all: drive not ready : Invalid argument So I use idescsi (or whatever this is called these days). When I try to write something: dd if=/etc/passwd of=/dev/pktcdvd0 bs=2048 the following happens (syslog): pktcdvd: v0.0.2p 03/03/2002 Jens Axboe (axboe(a)suse.de) pktcdvd: writer sr0 sucessfully registered pktcdvd: inserted media is CD-RW pktcdvd: Fixed packets, 32 blocks, Mode-2 disc pktcdvd: Max. media speed: 4 pktcdvd: speed (R/W) 6/4 pktcdvd: 551488kB available on disc I/O error: dev 0b:00, sector 0 pktcdvd: pktcdvd0: WRITE error sector 0 pktcdvd: pktcdvd0: WRITE error sector 4 pktcdvd: pktcdvd0: WRITE error sector 8 pktcdvd: pktcdvd0: WRITE error sector 12 pktcdvd: pktcdvd0: WRITE error sector 16 pktcdvd: pktcdvd0: WRITE error sector 20 pktcdvd: pktcdvd0: WRITE error sector 24 pktcdvd: pktcdvd0: WRITE error sector 28 pktcdvd: pktcdvd0: WRITE error sector 32 pktcdvd: pktcdvd0: WRITE error sector 36 pktcdvd: pktcdvd0: WRITE error sector 40 pktcdvd: pktcdvd0: WRITE error sector 44 pktcdvd: pktcdvd0: WRITE error sector 48 pktcdvd: pktcdvd0: WRITE error sector 52 pktcdvd: pktcdvd0: WRITE error sector 56 pktcdvd: pktcdvd0: WRITE error sector 60 pktcdvd: pktcdvd0: WRITE error sector 64 pktcdvd: pktcdvd0: WRITE error sector 68 pktcdvd: pktcdvd0: WRITE error sector 72 pktcdvd: pktcdvd0: WRITE error sector 76 pktcdvd: pktcdvd0: WRITE error sector 80 pktcdvd: pktcdvd0: WRITE error sector 84 pktcdvd: pktcdvd0: WRITE error sector 88 pktcdvd: pktcdvd0: WRITE error sector 92 pktcdvd: pktcdvd0: WRITE error sector 96 pktcdvd: pktcdvd0: WRITE error sector 100 pktcdvd: pktcdvd0: WRITE error sector 104 pktcdvd: pktcdvd0: WRITE error sector 108 pktcdvd: pktcdvd0: WRITE error sector 112 pktcdvd: pktcdvd0: WRITE error sector 116 pktcdvd: pktcdvd0: WRITE error sector 120 pktcdvd: pktcdvd0: WRITE error sector 124 Of course the data does not end up on the disc. Any idea? How can I debug this? - Jens

Success And Thanks
by Vernon Van Steenkist 10 Jan '04

10 Jan '04

First, I would like to thank everyone that has contributed to the Linux packet writing project. I really appreciate all your efforts. I would like to report success using Linux kernel 2.4.22 and an HP 9300 IDE CD/RW. After perusing the mailing list, I performed the following which is slightly different from the instructions at http://cvs.linuxfromscratch.org/index.cgi/hints/Attic/cdrw-hint.txt?rev=1.3 * For formatting the disk I used the command cdrwtool -d /dev/scd0 -q -t 4 . I added the -t 4 because I am using 1X-4X 650 MB Maxell RW CDs. Please note that it can take over 40 minutes to format a disk. * As stated in Richard's document, I can confirm that you do need to add the line alias block-major-97 pktcdvd to your /etc/modules.conf file if you build pktcdvd as a module and you want the kernel to automatically load it. I can now quickly copy, delete and move files from/to/on my CD RW just like any other drive. Needless to say, I am impressed since before I was constantly burning ISO9660 images every time I wanted to add or delete files. My portable CD player (Riovolt PSX100) recognizes these UDF linux written CD RWs (I believe the IRIVER portable CD players and others recognize packet written CD RWs as well). This has allowed be to easily and quickly add and delete MP3s to my CD RWs. Thanks once again to everyone involved.
