relavent lines from dmesg:

rebooted with lilo option hdd=ide-scsi

when I try to mount the burner
with mt /mnt/cdburner I get this:
mount: /dev/scd0 is not a valid block device

This is the case even if i don't use the cdburner link, instead using scd0 for everything.

Also, when I run cdrecord -scanbus
I get this:
No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.


What am I missing?

perhaps you do not have all of the necessary modules installed.

relavent lines from my lsmod:

sd_mod 10924 0 (unused)
sr_mod 14392 0
sg 29164 0
ide-scsi 8880 0
scsi_mod 88868 4 [sd_mod sr_mod sg ide-scsi]

Those modules don't exist on my system as far as I can tell. Where do I get them? I don't recall any modules installation instructions in any of the HOWTO's or messages I read.

Could you please post the results from

ls -al /dev/hdd

Your modules are in /lib/modules/<kernel version>/kernel/drivers. Look in the scsi directory.

Try loading the modules manually.

modprobe sr_mod

and then lsmod again as modprobe will also load the required modules that are dependent on the module you are loading.

Load the remainder as necessary.

Then try cdrecord -scanbus again.

Well, I ran through a tutorial of CD Burning for my particular distribution (slackware) which involved recompiling the kernel. Still no luck.

ls -al /dev/hdd:
brw-rw-r-- 1 root disk 22, 64 Jun 9 14:27 /dev/hdd

I ran modprobe sr_mod and I get this in lsmod:
sg 24380 0 (autoclean) (unused)
ppdev 7788 0 (autoclean)
sr_mod 13456 0 (autoclean) (unused)

plus alot of snd and printer stuff

I think the other modules are not showing up because I compiled them into the kernel.

cdrecord -scanbus gives this:
Cannot open '/dev/pg*'. Cannot open SCSI driver.

I think I'm close, just missing something.

[gleather]

Well, I installed kernel 2.4.19 with help from another post in the technical support forum and now xcdroast sees my burner.

THanks everyone.

I was just going to suggest you continue on with the loading of the remaining required modules.

Glad to see you got it working.
