Correct Setup for two SCSI CD devices?

Budgie2 · 02-10-2009, 02:40 PM

Hi, my first post on this forum so here goes.
I am using OpenSuSE 11.1 on a machine with two SCSI CD devices, a CD-ROM and CD-RW.

Some software, in particular KAudioCreator seems to be confused about which drive to use. There is a drop down menu for drive selection but it only offers the one choice cdrom. If I put a CD in either drive it is eventually detected but it takes an age and I am also getting errors.

In the system, KDE shows the drives correctly identified at /dev/sr0 and /dev/sr1 but in /dev both cdrom and cdrw drives are soft linked to sr0. Why is that? Could it be the cause of my problems and would it not be better to have the soft links sr0 & sr1 respectively?

I had all this sorted a couple of years ago in SuSE 10.0 but everything now has changed and I am finding it hard going.

Some guidance on the correct way to have the two drives installed would be much appreciated.
Thanks,
Budgie2

I don't have much insight into you problem, but since no-one else has answered I'll make a couple of comments and hope someone else can give you better advice

Try command 'cat /proc/scsi/scsi' to see how things are set up.

Also your description of the links in /dev is not very clear. Maybe you could be a bit more specific. On my setup I have /dev/sr0 -> scd0, for example.

Do SCSI devices have some sort of switch to set their IDs when multiple devices are chained together? Could that be a source of problems?

Hi and thanks for the suggestions. Am not at machine now so will try your command suggestion tomorrow. Also will try and copy the several lines in /dev which refer to cd.
