cdrecord -help
 

I normally use cdrecord to burn an ISO image onto a disc with 13.37, but on my desktop I have 14.0 and using

cdrecord -scanbus

doesn't identify my dvdrw.

are you running a custom kernel?
"cdrecord -scanbus" should work fine (using the scsi emulation driver) as long as you got the sg module loaded.
try, as root,

Thanks ponce, loading that module worked :-)

Curiosity, why do you need to load the module with 14.0 and not 13.37?

It's probably being loaded by one of the start up scripts. My best guess is the rc.modules script.

I just ran into this after upgrading to 14.0. I think the Slackware 13.37 kernel (2.6.37) loaded the module "sg" automatically when a disk device was discovered, and the Slackware 14.0 kernel (3.2.29) does not. The cdrecord commands require that module, so they won't work under Slackware 14 unless you load the module manually or in a startup script.

But I'm just guessing. I don't really know why this is happening. I do know that my 13.37 rc.modules did NOT specifically load the sg module - it just happened, and 14.0 doesn't do it.
