hi joao, Thank you for your reply, but I got the same error result when running "cdrwtool -m 295264 -d /dev/hdc" according to your suggestion. Could you give me more hints on that? I also tried to fake my atapi device as scsi device. but when running "cdrwtoo -d /dev/scd0 -q", this time it prints out sr0: CDROM (ioctl) reports, ILLEGAL REQUEST. Any help will be appreciated. Thank you in advance. Best Regards, kurt Joao Luis Meloni Assirati wrote: On Wed, 17 Mar 2004, ke chen wrote:

[...] This also happens to me. I have an LG GCC-4480B (CDRW + DVD reader combo). I don't know why things are in this state, but I first use cdrwtool -d /dev/hdc -q , wait the failure and read the disk capacity (in your case, 295264) and use cdrwtool -m -d /dev/hdc This will perform a low level format. After it finishes, I use pktsetup /dev/pktcdvd0 /dev/hdc mkudffs /dev/pktcdvd0 (you should have some script to do the pktsetup at boot time). After that, you will be able to mount /dev/pktcdvd0 read-write.

hi Joao, Thank you for your reply. But it doesn't work when i use cdrwtool -m 295232 -d /dev/hdc, or with other smaller number. i tried to copy some documents into the cd-rw disc with another cd-writer in a windows machine. and then came back to use cdrwtool to blank it in linux. This time, it seems a little better, it print out "initiating quick disc blank", but after a while, still pop up the almost same error message except that one "cdrom: this disc doesn't have any tracks I recognized" I am really lost on it and hope some person can help me. Thank you very much. Best Regards, kurt Joao Luis Meloni Assirati wrote: Kurt, On Wed, 17 Mar 2004, ke chen wrote:

Try to reduce the disk capacity, say cdrwtool -m 295232 -d /dev/hdc or less. Maybe it works for some smaller number. I don't know well the underlying principles, but remember seeing this advice somewhere...

I also tried to fake my atapi device as scsi device. but when running "cdrwtoo -d /dev/scd0 -q", this time it prints out sr0: CDROM (ioctl) reports, ILLEGAL REQUEST.

That should not be needed, even for burning cds in the ordinary way. You may know that cdrecord now has support for atapi.

Hi Chris, Thank you for your information. Actually, i have already had a try on scsi emulation and it doesn't work. But with different error message cdrwtoo -d /dev/scd0 -q", sr0: CDROM (ioctl) reports, ILLEGAL REQUEST Thank you very much. I still need help from others to make it work. Any advice will be appreciated. BR, kurt Chris Clayton wrote: On Wednesday 17 Mar 2004 08:25, ke chen wrote:

hi all,

It's quite a while since I set up packet writing on my system so this may not be correct but, since we have a 2.4.x kernel, doesn't scsi emulation (ide-scsi) come into play somewhere? Regards Chris

I followed the document on http://linuxfromscratch.org/pipermail/hints/2002-August/001207.html and tried to carry on packet writting, but failed even when making disk quick setup.

my cd writer: CD-W224EA, ATAPI CD/DVD-ROM drive linux kernel 2.4.23

download the patch packet-2.4.23.patch.bz2 from http://w1.894.telia.com/~u89404340/patches/packet/2.4/

compile the kernel with options: Packet writing on CD/DVD media UDF files systems support (read only) UDF write support (DANGEROUS)

after reboot mknod /dev/pktcdvd0 b 97 0

download package udftools-1.0.0b2.tar.gz from http://sourceforge.net/projects/linux-udf then install cdrwtool

insert a blank highspped rewrittable disc, [root@localhost /]# /usr/bin/cdrwtool -d /dev/hdc -q -t 4 using device /dev/hdc setting speed to 4

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.

Can anybody help me out?
