So I'm trying to burn an .iso...and I've used cdrecord -scanbus...and this is what comes up:

Code:

root@Rob&#58;/home/rob# cdrecord -scanbus

root@Rob&#58;/home/rob# exit

Any advice? Thanks in advance!

What distro, which kernel version?

**Javasnob** · 10-02-2005

Debian Etch, 2.6.13.2 kernel.

Do you have the scsi- and atapi-scsi-emulation-modules loaded?

**Javasnob** · 10-02-2005

From what I see from lsmod, no, I don't have them loaded, and kernel modules aren't exactly friendly with me. How do I know which modules are available? (I know to use insmod to load them).

Thanks again!

Try modprobe instead, it will find the path of the modules automaticly... However, here is the path to the modules-hierarchy: /lib/modules/*/

There you will find them sorted up... I think atapi-scsi emulation is needed to use ATA-cdwriters with cdrecord...

No, SCSI emulation is no longer required with 2.6 kernels. However, cdrecord is rather broken with these kernel changes. You can burn with it, but scanbus won't work. The best solution is to determine the /dev location your drive is at (/dev/hdc if it's master on the second channel) and use dev=/dev/hdX

You can find your drive's /dev entry by trial and error this way:
# cdrecord -scanbus dev=/dev/hdc
I just like to use the specific IDE device, you can usually use something like /dev/cdrom or /dev/cdburner or /dev/cdroms/cdrom0

It will give you an error message if it's the wrong location, but will show your drive if it's correct.

Here's a good CD Burning doc, but not everything is up to date, especially considering 2.6

Of course, SCSI emulation is still available in the 2.6 kernel, and as long as it's built into yours you can use it. But considering it's always been a hack, it's probably a good idea to move away from it now.
