h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

how to I get my cdr working? I'm using Slackware 10.2

I have a CD drive (hdd) and a combi cd/cdr/dvd (hdc) both are IDE.

my fstab looks like
/dev/hda2 swap swap defaults 0 0
/dev/hda4 / ext3 defaults 1 1
/dev/hda3 /home reiserfs defaults 1 2
/dev/hda1 /c ntfs ro 1 0
/dev/cdrom /mnt/cdrom auto noauto,user,ro 0 0
/dev/cdrom2 /mnt/cdrom2 auto noauto,user,ro 0 0
/dev/dvd /mnt/dvd auto noauto,user,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,user 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

cdrom & dvd point to the combi device.

"cdrecord -scanbus" comes up with
Cdrecord-Clone 2.01 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'.
cdrecord: For possible transports specifiers try 'cdrecord dev=help'.

Do you have a kernel you compiled yourself?
If so you need to add in the scsi generic functionality as CD recording uses some of these drivers - thats why it's complaining about scsi drivers.
The other thing is do you mean /dev/sg* as these are the scsi generic devices (not /dev/pg*) If you have scsi-generic in the kernel (or a loadable module) but don't have the devices in /dev then it'll have problems. Use either the makedev (make /dev/MAKEDEV /dev/sg* or similar) or mknod /dev/sg0 c 21 0
You may also need the scsi cd drivers as well (I know it's an IDE drive but that's what's needed).
