cdrecord with 2.6.11.8 kernel

There's no reason, just don't use -scanbus, it's good for nothing except the SCSI bus. You can record directly to a CD on a 2.6 kernel using, in your case:

Code:

cdrecord dev=/dev/hdc [rest of command]

Yep, there is no need to use "-scanbus" at all if you are using a 2.6 kernel. "cdrecord -scanbus" was for 2.4 kernels that were using ide-scsi emulation.

I found that cdrecord commands that used to work need to be altered in order to get them to work. I used to use cdrecord from the command line all the time. However, k3b is so good at figuring out the right options to give to cdrecord that I now almost always use k3b, even if I am not running KDE at the time I want to use it. I just used it to burn a quick CD/RW erasable CD containing systemrescuecd and it worked great! I'm sold on using k3b as my primary CD burning utility!

i love k3b, after i was doen burning a cd, i click on teh debug button and it shows me the cdrecord command and all its agrs that it used to burn that cd. So by using k3b, i can know use the command line to burn cds. and writes scripts also

k3b rocks

thanks,

Just issue cdrecord with -v and you see it all ...

To do burning using kernel 2.6 and not using the discouraged way (dev=/dev/whatever),
use

Code:

dev=ATA:x,y,z

The "coefficients" can be obtained by the following command.

Code:

cdrecord -v dev=ATA -scanbus

At least this works for me since kernel 2.6.7. But one more tip: If you are using
kernel 2.6.8 or 2.6.8.1, don't ever try to burn in DAO mode, because it
can crash your system, unless you have VERY VERY BIG RAM. Nonetheless,
solution is simple -- just upgrade to 2.6.9 or newer.

Why is that discouraged when it works fine?

AFAIK it's discouraged because of DMA issues. But for more information please consult the documentation and sources. cdrecord uses it's own library to send command to burner. Moreover, /dev/whatever is kernel block device and for this reason the kernel occasionally stops commands whose meaning is unknown for the kernel. This is true especially for unprivileged user access.
