are you using

Code:

# cdrwtool -d /dev/hdc -q

and what do you have in /dev/pktcdvd ?

mvh

Edit: try (NB! change 'hdc' for your device)

Code:

# cdrecord blank=fast dev=/dev/hdc

and retry cdrwtool

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. 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.

Initiating quick disc blank
wait_cmd: Input/output error
Command failed: a1 01 00 00 00 00 00 00 00 00 00 00 - sense 05.24.00
blank disc: Illegal seek

Code:

I hope this helps...

btw /dev/hdc is my cd-rom drive.

how about dvd+rw, does that work?

Code:

# dvd+rw-format /dev/hdc
# mkudffs /dev/pktcdvd/0

Btw did you set these in the kernel config

Code:

# CD-ROM/DVD Filesystems
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y

and you did run
# pktsetup 'hdc' /dev/hdc where 'hdc' is whatever you called it in fstab?

have you done

Code:

# rc-update add pktcdvd default

fstab for my two burners is :

Code:

/dev/dvd /mnt/dvd iso9660 noauto,user,rw 0 0
/dev/dvd1 /mnt/dvd1 iso9660 noauto,user,rw 0 0
/dev/pktcdvd/hdc /mnt/dvdrw udf noauto,noatime,rw,user 0 0
/dev/pktcdvd/hdd /mnt/dvdrw1 udf noauto,noatime,rw,user 0 0

NB! one could use /pktcdvd0 & 1 (or 0 & 1 perhaps) instead of /hdc and /hdd

I think thats it for now.. hope something helps ;-)

Edit: Oh yes, what version of kernel are you using, and what burner model?

dvd+rw-format doesn't work, because my burner can't burn DVD's

I have a QSI SBW241 (as you can see in the output of the different programs). Is a laptop DVD/CDRW combo drive. In windows it's working fine, so on the hardware level there's nothing wrong.
I'm running the 2.6.16-r1 kernel at the moment, but I'm trying to get it to work for at least half a year now. So I've tried a lot of different kernels in the process.

My kernel is compiled with

Code:

# CD-ROM/DVD Filesystems
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y

And I run pktsetup as told.

Btw, how kan I make the pktcdvd devices permanent in a 100% udev controlled /dev? Because on a reboot I get a /dev/pkcdvd/control device and I have to re-run pktsetup.

Hei & Happy Easter

http://lists.suse.com/archive/packet-writing/2004-Oct/0033.html is rather old but very much like what you experience.. I'm not on Gentoo at the moment so I can't tell you how I fixed the pktsetup reboot problem, other than to stick the line in Konqueror > Go > Autostart.

I've read the article, and the option -immed does make cdrecord usable to blank cdrw's. The sad thing only is, that the guy posted this article 1,5 jaar ago, and it seems that the developers of cdrwtool ignored it. So the option doesn't work for cdrwtool... At least I know what's wrong... (and I think it could be easily fixed...)

You can use the /etc/init.d/pktcdvd script automatically by doing:

Code:

rc-update add pktcdvd default

This will set up all CD-RW and DVD+/-RW burners for packet writing. The script installs as part of the udftools package.

If you want to be selective, you can put pktsetup commands inside /etc/conf.d/local.start instead, but if you have only 1 burner then the automatic approach is simpler.
