No hdc? Where did it go?


Hello everyone, I have installed RHEL4 on my computer, which has a single harddrive, a DVD-Burner and a DVD-ROM (hda,hdc,hdd respectively). I recently changed from FC4 to RHEL4, and noticed that, when I put a DVD in my burner, it wouldn't read it. I thought this was odd, so i turned off my computer and checked the connection to the back of the device, and it's fine. I then reboot, and still it won't read the DVD.

So, I poke around to see what the problem may be, and I get the following:
Code:
# ls -l /dev/ | grep hd
lrwxrwxrwx  1 root     root          3 Sep  8 15:35 cdrom -> hdd
lrwxrwxrwx  1 root     root          3 Sep  8 15:35 dvd -> hdd
brw-rw----  1 root     disk     3,   0 Sep  8 15:35 hda
brw-rw----  1 root     disk     3,   1 Sep  8 15:35 hda1
brw-rw----  1 root     disk     3,   2 Sep  8 15:35 hda2
brw-rw----  1 root     disk     3,   3 Sep  8 15:35 hda3
brw-------  1 jgrindal disk    22,  64 Sep  8 15:35 hdd
you'll notice the blatant absence of hdc. Is there anything that can be done with the OS, or does the problem lie with the cable and/or the device itself?

Have a look at the output of dmesg. If you can't find any
mention of the dvice at all you have a hardware problem.

If it DOES show, chances are that it made it into a ide-scsi
device, but that, too, will show in dmesg.


Cheers,
Tink

Thanks for the quick response - this output is massive! Anything particular that I should be looking for?
Thanks again.

Ok, I found the part that could shed some light on the issue, but I'm not sure what all this means.
Code:
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on pci0000:00:0f.1
    ide0: BM-DMA at 0xd400-0xd407, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xd408-0xd40f, BIOS settings: hdc:DMA, hdd:DMA
Probing IDE interface ide0...
hda: ST380013A, ATA DISK drive
Using cfq io scheduler
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

ide1: Wait for ready failed before probe !

Uniform CD-ROM driver Revision: 3.20
ide-floppy driver 0.99.newide
usbcore: registered new driver hiddev
The system recognized hda and hdd, but hdc isn't there either...
Any help on what this means?

Most likely a hardware problem, as I said earlier.

Wether the data cable is loose, the power chord
wonky or the drive just dead I can't tell ...
