13 Well that isn't good!

15 What you should be seeing is something like this:
16 ~ > /sbin/cdrom_id --export /dev/hdc; echo ; /sbin/ata_id --export /dev/hdc
17 ID_CDROM=1
18 ID_CDROM_CD_R=1
19 ID_CDROM_CD_RW=1
20 ID_CDROM_DVD=1
21 ID_CDROM_DVD_R=1
22 ID_CDROM_MRW=1
23 ID_CDROM_MRW_W=1
24 ID_CDROM_RAM=1
25
26 ID_TYPE=cd
27 ID_MODEL=PIONEER_DVD-RW_DVR-110D
28 ID_SERIAL=
29 ID_REVISION=1.17
30 ID_BUS=ata

32 Was this done after following my earlier advice to modularize your IDE
33 system, and if so, did you load the necessary modules (modprobe ide-cd
34 it821x)?
35
36 If so, the kernel should be finding the devices. What does "find /sys
37 | grep /ide" report?
38
39 Can you send me your full dmesg output?
40
41 Can you try removing one of the drives (hdb)? Maybe this is a hardware issue...
