problems with cd-rw, maybe due to scsi hard drive?

McVeigh

I can't get my cdrw to work.

I have
append="hdc=ide-scsi"
in grub

i have scsi support in the kernel.

cdrecord --scanbus gets me this
Cdrecord 1.11a19 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J�rg Schilling
Linux sg driver version: 3.1.23

0,4,0 4) *

no mention of my cdrw,

I do get an error during boot up about this device asking if I should use /dev/sr0 or something
line from /etc/fstab
/dev/cdroms/cdrom0 /mnt/cdrom0 iso9660 auto,users,rw 0 0

any ideas?

You surely don't have all appropriate things loaded or compiled one, make sure that you have scsi emulation in the kernel also.

seth@midas seth $ cat /proc/cmdline
root=/dev/sda5 hdc=ide-scsi

that is with a new kernel and the grub line changed to read similar to yours.

partial success!! I am buring an an ISO image as we speak, using cdrecord. cdbakeoven choked and I still get all kinds of errors during boot up, I'm trying to find where the logs are on my new system

Just to sum it up incase someone stumbles over the same problem, you deleted your append line and modified your kernel line, correct?

By the way, append is a LILO variable, not a grub variable.

well some thing sthat have helped,
i changed the grub line--this really needs to be in the documentaion somewhere.
in my etc /fstab i changed the line dealing with my cdrw to
/dev/cdroms/cdrom0 /mnt/cdrom0 iso9660 auto,users,ro
i had set it to rw because I thought I wouldn't be able to write to it.

but yes I think the key was the grub line.

Thanks again.

now to get it working in a graphical mode :cry:
