Plexwriter 12/4/32 SCSI


I just built a linux-only box running Slackware 10.0. Everything works, except my Plextor 12/4/32 SCSI CD writer doesn't seem to show up. It's connected properly, but I just don't know how to set it up. Help anybody? I can't seem to find any information on SCSI CD-writers and Linux.

Thanks.

What SCSI controller are you using in this PC? Does the controller recognize the drive during the boot scan? Do you have other SCSI devices on the same bus? What about the SCSI modules? Look at the output of /sbin/lsmod.

The drive will have a device ID of /dev/scd0, assuming its the only SCSI CDROM drive in your system.

The following command will list the SCSI devices if the modules are loaded.
cat /proc/scsi/scsi

Adaptec 29160. It recognizes the drive during the boot: it shows up in the SCSI BIOS during boot time. I also have a Seagate SCSI Hard drive attached to it which is the location of my root and /usr partitions. .

Nothing list for cat /proc/scsi/scsi?
What SCSI modules are loading?
/sbin/lsmod

using cat/proc/scsi/scsi it shows up. Here's the complete list:

Attached devices:
host: scsi- Channel: 00 Id: 00 Lun: 00
Vendor: SEAGATE Model: blahblahblah
blahblahblahblah

Host: scsi- Channel: 00 Id: 04 lun: 00
Vendor: PLEXTOR Model: CD-R PX-W124TS Rev: 1.06
Type: CD-ROM ANSI SCSI revision: 02

It seems fine; it's just that I can't "find" it. I went into KDE and looked under the devices icon. My other DVD-ROM drive shows up, but not the Plextor.

Do you have a /dev/scd0 device?

Is the sr_mod module loading?
Check via the output of /sbin/lsmod

So can you manually mount a data CD?

I started typing before you posted the no sr_mod module. Without the sr_mod loaded you probably will not be able to mount the CD. So try:

modprobe sr_mod

Now try manually mounting a data CD.

via-rhine is the ethernet module.
ide-scsi is for SCSI emulation. Do you have an IDE CDRW?

My IDE is just a DVD-ROM drive. No writing things. When I try to edit most config files, I keep getting this message:
Note: /etc/modules.conf is more recent than /lib/modules/2.4.26/modules.dep even when doing modprobe sr_mod
And when I edit the "more recent" file, it's blank.

Anyhoo, I did modprobe sr_mod and got that mesage, below it is:
modprobe: can't locate module sr_mod
