I've taken all the steps but cdrecord still shows no drives?

On my system I have a cdrw installed on /dev/hdc. My burner worked back in redhat, mandrake and a previous debian install but I'm having no luck this time around. At first I thought it was an ide-scsi issue, but I can load the module (I recently compiled it in, so no more loading it) and mount /dev/scd0. I also have both scsi support and generic scsi support compiled into the kernel I'm running. I even added 'options ide-cd ignore "hdc"' just to be sure. Below is some output that I think might help diagnose the problem:

Code:

chris@onizuka:~$ cat /proc/scsi/scsi

Attached devices:

Host: scsi0 Channel: 00 Id: 00 Lun: 00

  Vendor: CyberDrv Model: CW058D CD-R/RW  Rev: 100D

  Type:  CD-ROM                          ANSI SCSI revision: 02



chris@onizuka:~$ sudo mount /dev/scd0 /cdrom

mount: block device /dev/scd0 is write-protected, mounting read-only



chris@onizuka:~$ cdrecord -scanbus

Cdrecord 2.01a05 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J?rg Schilling

Using libscg version 'schily-0.7'

cdrecord: No target found.

Any ideas? (Thanks btw)

Hello,
I think you have to be root to use cdrecord.
(Or changeing the file permission of /dev/scd0 may help as well.)

Same effect if I use sudo, so that isn't it

I've never tried to scsi-detect a mounted device,
and currently don't have access to my burner
(a colleague has it) ... my wild guess is that a
mounted device won't accept low-level SCSI
commands from other applications.

What if you manually tell cdrecord
to use the device?

cdrecord -dev=0,0

Cheers,
Tink
