Ok. Ive followed every guide that i can find. Ive made a ide-scsi module, added "hdc=ide-scsi" to my lilo.
Made the devices ("mknod /dev/scd0 b 11 0", "mknod /dev/scd1 b 11 1")

When i run "cat /proc/scsi/scsi" it gives me
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: HP Model: CD-Writer+ 8100 Rev: 1.0g
Type: CD-ROM ANSI SCSI revision: 02

Ok, this seems ok doesnt it?
But whenever i try to mount it mount gives me:"/dev/scd0 has wrong major or minor number"
Even though ive created the scd[0-1]s with the numbers given in /usr/src/linux/Documentation/devices.txt

Does anybody know what the problem can be?

Sorry to answer your question with more questions, but this will kick it to the top and perhaps give you a clue as to what is wrong.

You say you cannot mount it, is there an entry for it in /etc/fstab? Have you tried burning CDs with it - say in X-CD-Roast?

I have heard of this problem before when the CDR is the only drive in the system. Will it mount as /dev/hdc?

The scsi generics are on either

sr0, sr1 (mine)

sg0, sg1 (in all the tutorials ive read)

You need to set up these device files, instead of scd0, scd1. To check its all working ok, try

cdrecord -scanbus

Now I've created the sr[0-1] and sg[0-1] but they give exactly the same error as scd[0-1].

I cannot mount it from /dev/hdc - "special device does not exist"

I have two cdroms so its not the only cd in the system.

I have a correct entry in fstab. But I have also tried without it with no success.
