cdrecord -scanbus finds no devices. What now?

[sheepdog]

Linux is getting better and better but there are 3 things that remain persistently broken and an absolute obsticle to its widespread adoption:

• Printing
  Sound Mixing
  CD Burning

I spend more time struggling with these three things than anything else in the operating system.

Right now I cannot get my CD-RW drive to write. I have been through the several threads in the forum about how to do this without relief. The setup:

Gentoo 1.4-rc1
Sony IDE CD-RW

lsmod:

• sg
  ide-scsi
  scsi-mod [sg ide-scsi]

grub has been modified to

Code: Select all

kernel bzImage root=/dev/md2 hde=scsi

Yet

Code: Select all

cdrecord -scanbus

tells me there is nothing there.

Any assistance would be greatly appreciated.

Have you seen kerframil's Kernel SCSI emulation for CD burning - the truth?

Yes, I have, and I attempted to follow it precisely. Which reminds me that I did modify the /etc/modules.conf file with

Code: Select all

options ide-scsi ignore='hde'

OK, then, so quietly now, in case kerframil is listening , but have you tried turning IDE CD support off?

[jbradley]

My grub menu.lst file has the line:
kernel /boot/bzImage root=/dev/hda2 hdc=ide-scsi

You list your's as having:
kernel bzImage root=/dev/md2 hde=scsi

Unless you have an addon IDE card that gives you a couple of additional ide drive ports, in addition to the 4 drive ports that your motherboard probably has, you shouldn't have an hde drive. It would be the master drive of a 3rd controller, with hda being the master of the first controller, hdb the slave of the first, hdc the master of the second controller, and hdd being the slave.

Good idea! It worked. I now see the CD with cdrecord -scanbus. Thank you. Guess it is important to remove IDE support from the kernel. (I'm whispering quietly).

Yes, that's right. Good catch. I do have an addon IDE card just for the CD-RW. The onboard IDE channels are used for a RAID 1 array and the system wouldn't allow a RAID 1 array with a CD on one of the channels, too.

Took three tries but finally was able to burn an ISO to CD.

k3b has a SEG FAULT bug when you try to burn ISO's. This bug has been submitted to KDE.

Next tried Arson, but this application errorred while trying to burn the ISO. The error output did not make it clear why.

Finally used cdbakeoven and that application burned the ISO without error, although the usage could have been much clearer.

Thanks to all for the essential assistance.

Works for me, always has. I've been having real burnfests with ISOs here, Gentoo PPC, FreeBSD, other Linux distros CDs, you name it, all with K3b.

I got the segfault on k3b when I tried to burn an ISO as well under my normal username. I then logged in as root, burned an ISO successfully and upon logging in with my normal user again I could also burn an ISO. <shrug> Oh well, at least it works on one of my systems now! Still having trouble on my main PC at home, but I was glad to get my work machine going.
