September 2002 - Packet Writing - openSUSE Mailing Lists

Waiting for suggestions after initial experiences
by Toth Attila 05 Oct '02

05 Oct '02

First of all I want to say thank you to Jens Axboe, Peter Osterlund, Ben Fennema, and all the others, who participated in making Linux packet writing avaiable. I first tried the patch long time ago without success (when it was maintained by Axboe). Now I had the time to look further into the issues and finally I managed to make it work. I'm using an Acer 4x4x32x IDE-ATAPI CDRW connected to the PIIX4 ide controller of my Abit BP6 motherboard (it also has a hpt366). Let me mention, that this writer shows some strange symtoms: firmware updater programs haven't been able to find the writer on the ide bus for some time and the writer does not care about the specified grabbing and writing speeds, it just operates at approx. 2,5x speed. The latter one doesn't refers to packet writing, when it seems to keep the desired speed. It can handle rewritable discs well in Windows (using InCD or DirectCD). Once (in the past: 2 year ago+) it created some disks with errors. I tried to stress it with writing 10 CDs to crash it totally before I lost the guarantee. It created dosens of CDs after that without errors. Now I continue with my recent experiences. I compiled the kernel with packet-2.4.19-2.patch. My kernel based on a 2.4.19-rc1 gentoo kernel with some additional patches from Andrea Arcangeli. Because it is an -ac series kernel from the packet point of view, I modified slightly the patch based on the information appeared on this mailing list. I'm using udftools-1.0.0b2. The writer resides on the PIIX4, because it is a more stable product than the hpt366 IMHO. I didn't tune the writer with hdparm. It didn't change anything. Modules were loaded OK. When I tried to quick-setup the disk with cdrwtools, everything seemed to be fine. It produced a CD which I couldn't mount. Some I/O errors showed up and it said that no UDF filesystem could be found. After some retries I tried to format the disk with mkudffs. At the first attempt it flooded the screen with read errors. When I repeated this step it produced further 'just' to I/O errors. I succesfully mounted this CD and copied files on it (full) and deleted them without errors. After I mounted a DirectCD-formatted disk, I faced with a bounch of WRITE errors, and an irq timeout followed by an ATAPI reset. The best of all: I could use the Linux-formatted CDRW disk by DirectCD and InCD! (Some DirectCD formatted disk can't be used on specific InCD machines...) I suspect, that my writer may not be reliable at 4x speed. The kernel recognise it as a 4x rewriter. The disks used are brand new (Linux-formatted) or known to be good (Windows-formatted), and capable of 4x speed. I also met a problem with my new LinuxUDF CDRW. I copied some file using DIrectCD by WinCommander from a CD. The CD contained old-DOS fashioned files and directories (8.3, all uppercase). I've also copied some other files on the disk at the same time. I can see the copied CD contents only under Windows, while the other files can also be seen on Linux. My questions: 1. Why is it, that the windows formats the disk slightly bigger? Size does not matter for me, but it is a clear difference I've found between the disks. It doesn't bother me, if it is not related to the above presented problems. 2. What can be the reason, that quick-setuped disk couldn't be mounted, but mkudffs-formatted could? 3. What sould I do with these I/O errors (and also with WRITE and read errors possibly related to them)? May I ignore the I/O errors during mkudffs, because the resulted disk seems to be fine? 4. Should I specify lower writing speed somehow, or I should cure my paranoidity? 5. Maybe there are some timing issues with this drive related to the irq handling and so. What should I do? 6. What can be a reason my latter presented problem? Feature request: 1. The possibility to set writing speed explicitly.

29 Sep '02

hi all, i am trying packet writing on a CD-R. whats the concept of writing the VAT. should the VAT be written everytime a packet is written or the VAT should be written at the end, when the disk is ejected. iam regulary updating the VAT as and when entries are added or deleted. If this question does not correspond to the exact requirements of this group, pls forgive me and ignore this mail. awaiting ur suggestion. D.Sridhar

Yamaha CRW-F1
by Stephen Mollett 21 Sep '02

21 Sep '02

Hi, Does anyone know if Yamaha's new CRW-F1 (44W/24RW) works with pktcdvd? My old CRW4416S is getting a bit cranky and I'm thinking about getting the internal SCSI version of the F1 to replace it. (I've always found Yamaha writers to be reliable and to produce high-quality discs; my experience with other makes has been rather unfavourable.) (The alternative that I'm considering would be a Firewire Sony DRX-120L DVD+RW but I've heard that there are problems getting this to work with Linux at all.) Thanks, Stephen

Hi All Folks, I just join this list and package writing/reading in Linux environment is completely new to me Has any folk on the list having experience in installing and using the udf packages from "souceforge" I have them installed but don't know how to proceed. Nor have any idea whether there are mistakes committed during installationn. Hereinafter is my tests RH7.3 ===== KOnCD and Xcdroast work properly.

Re: Problem with Tekram controller
by Kirill Messel 17 Sep '02

17 Sep '02

Hi all, I've checked: CDRW is insearted, Properly formated, i have checked it on Windows and tried to mount as udf disk on Linux. It looks udf file system. pktcdvd module is loaded. I can mount this CDRW as udf to read/write. And copy file to disk passed. But if i try to umount i have got a error, after that CD looks like not formated. What is the problem. May be Tekram controller could not work with udf system? Kirill > >You have one of follows: > > - disk is not inserted in CDRW drive > - not properly formatted UDF disk (check disk with chkudf utility) > - not loaded pktcdvd module (to list dynamic loaded modules rub lsmod) > - bad record in /etc/fstab >

packetwriting on a parallel cdwriter?
by Guy Forssman 13 Sep '02

13 Sep '02

Hi, Is it possible to do packetwriting on a parallel CD-Writer such as the HP 7510e? Kernel is 2.4.19 I compiled the pktcdvd.o module and the UDF file format but I get a error when I do this: pktsetup /dev/pktcdvd0 /dev/pcd0 gives me this: drive not ready :Function not implemented Thanks in advance Guy Forssman

cdrwtool formatting problems with scd0
by Leo Przybylski 12 Sep '02

12 Sep '02

Hello, I have been posting previously on a cdrw device and I have since solved my problems with that device. I've been trying since then with a different cdrw, so these questions are not related to the ones I've posted before. When I try to format a cdrw with the command: cdrwtool -d /dev/scd0 -m 1000 I get the following output: using device /dev/scd0 formatting 3000 blocks 1206KB internal buffer setting write speed to 12x wait_cmd: Invalid argument Command failed: 04 17 00 00 00 00 00 00 00 00 00 00 - sense 05.26.00 format disc: Illegal seek I continue to get this error until I raise the offset to >= 4000. Once I've done this it sits trying to format it for an hour or two until I eventually get the same error again. Any ideas? -Leo

Problems with packet-cd
by Frédéric L. W. Meunier 12 Sep '02

I tried with packet-cd 2.4.19-2 and UDF from CVS. cdrwtool -d /dev/sr1 -q using device /dev/sr1 8065KB internal buffer setting write speed to 12x Settings for /dev/sr1: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/sr1. 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.

DVD+RW format blank option
by guStaVo ZaeRa 12 Sep '02

12 Sep '02

Andy, I was wondering whether there is a quick fix to reset the dvd+rw formatted bit on the media, so that next time i insert it into the drive, it'll seem like a new, previously unwritten media. I've looked at your code, and it seems like doing something like this would work: if( formats[8] == 2 && bBlank ) { formats[8] = 1; /* or something like that */ /* write to DVD+RW */ } CheerS, gustavo

creating udf fs on cd

Hello, I have found that cdrwtool -d /dev/scd1 -q has caused problems for me, so to debug the issue I tried to first blank and format the disc using: cdrwtool -d /dev/scd1 -b full -m 4096 Then, I try to apply a udf fs with cdrwtool -d /dev/scd1 -u 4096 When I try writing the fs, I get the following output: using device /dev/scd1 mkudffs 4096 blocks 1282KB internal buffer setting write speed to 12x start=0, blocks=16, type=RESERVED start=16, blocks=3, type=VRS start=19, blocks=237, type=USPACE start=256, blocks=1, type=ANCHOR start=257, blocks=31, type=USPACE start=288, blocks=32, type=PVDS start=320, blocks=32, type=LVID start=352, blocks=32, type=STABLE start=384, blocks=1024, type=SSPACE start=1408, blocks=2400, type=PSPACE start=3808, blocks=31, type=USPACE start=3839, blocks=1, type=ANCHOR start=3840, blocks=160, type=USPACE start=4000, blocks=32, type=STABLE start=4032, blocks=32, type=RVDS start=4064, blocks=31, type=USPACE start=4095, blocks=1, type=ANCHOR Writing UDF structures to disc wait_cmd: Invalid argument Command failed: 2a 00 00 00 01 00 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 01 20 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 01 40 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 01 60 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 05 80 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 05 a0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 05 c0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 05 e0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 06 00 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 0e e0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 0f a0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 0f c0 00 00 20 00 00 00 - sense 05.21.02 wait_cmd: Invalid argument Command failed: 2a 00 00 00 0f e0 00 00 20 00 00 00 - sense 05.21.02 I also try mkudffs --media-type=cdrw /dev/scd1 4096 I do not get the same errors, but I still cannot mount /dev/pktcdvd0 after executing pktsetup /dev/pktcdvd0 /dev/scd1 I must be doing something wrong.

mkudffs issues II
by guStaVo ZaeRa 11 Sep '02

11 Sep '02

Hello again, following up from the mkudffs issues message i posted yesterday.. Looking at the mkudffs source, i found that the application (mkudffs) prints out an error message, and exits without further information when the blocks > start_ext->blocks.. do you have an explanation of what actually happens here, Ben? :) I'm getting this error each time i try to run the mkudffs app through a 'system' function call from a C++ program. Another thing, is that the code looks like this: if (start == start_ext->start) { if (blocks == start_ext->blocks) { ... } else /* blocks > start_ext->blocks */ { printf("trying to change type of multiple extents\n"); exit(1); start_ext->space_type = type; return start_ext; } ..... The statements after the exit(1) are never reached.... why are they there? Thanks, gustavo

Hello, when envoking 'system' from an application like the following code shows: // format media with UDF if( -1 == system( "/usr/bin/mkudffs --spartable=2 --media-type=cdrw --udfrev=0x0150 /dev/scd0" ) ) { fprintf( stderr, "OpticalDrive::formatMedia : format UDF : ERROR : %s\n", strerror( errno ) ); iRet = -1; } The system call itself does not give me a return of -1, so my error is not shown, but i see the following message: trying to change type of multiple extents If i execute the command in the command line, everything works ok. any comments? Should i do the system call with exec* instead? if so, why would it matter ? gustavo
