Hi,

Am having a problem with "cdrecord" not recognising my cd drive.

By way of background: knoppix 3.8.1, kernel 2.6.11, HD Install

from DMESG:

--------------------------
hdc: _NEC DVD+/-RW ND-6500A, ATAPI CD/DVD-ROM drive
hdc: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache
Uniform CD-ROM driver Revision: 3.20

I have followed the instructions in a post by Markus, so that the following are set:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
brw-rw-rw- 1 root cdrom 22, 0 Apr 14 2001 /dev/hdc
lrwxrwxrwx 1 root cdrom 8 Jun 2 19:36 /dev/cdrom -> /dev/hdc
lrwxrwxrwx 1 root cdrom 10 Jun 2 19:36 /dev/dvd -> /dev/cdrom
lrwxrwxrwx 1 root cdrom 4 Jun 2 19:28 /dev/sr0 -> scd0
lrwxrwxrwx 1 root cdrom 4 Jun 2 19:28 /dev/sr1 -> scd1
brw-rw---- 1 root cdrom 11, 0 May 30 2001 /dev/scd0
brw-rw---- 1 root cdrom 11, 1 May 30 2001 /dev/scd1

I found a post on the ubuntu forum that seemed to address the problem.

One suggestion was to add "hdc=ide-scsi" to the boot options but, it seems, that this is not a valid knoppix chear code, as DMESG showed the boot options as "Kernel command line: root=/dev/hda7 knoppix lang=us dma nodhcp" not passing the "hdc=ide-scsi" option.

The ubuntu article also suggested adding "ide-scsi' to the "/etc/modules" file but my changes were overwritten by the "knoppix-autoconfig" boot-time re-writing of this file.

The last part of the ubuntu article suggests modifying the "/etc/fstab" file to reflect the "new" /dev/scd0 device. Never got the chance to try this, as the "ide-scsi" approach failed.

So, am no further ahead in solving the problem.

Any help much appreciated.

Regards,

Geoff.
