[gentoo-user] mount: special device /dev/hdc does not exist. What does this mean?
Hi, Gentoo? I've a newly installed system, now working with my own special optimiesed keyboard layout. :-) However, I can't access my DVD drives. I know at least one of them works, because I installed Gentoo from it. When I do mount -tiso9660 /dev/hdc /cdrom , it comes back with special device /dev/hdc does not exist. And yes, there was a CD in the drive, and /cdrom exists. What does special device mean here? Does it mean the physcial hardware, the controller chip, the directory entry /dev/hdc, the driver in the kernel, or what? What is special about my DVD writer? Well, to answer some of my questions, I was missing a /dev/hdc, so I made one with # mknod /dev/hdc b 22 0 . This didn't help one iota. I had a look at dmesg, but there was no mention of hdc in it. (It did mention hdg, hdh, where my main hard drives are (don't ask!)). My kernel is an up to date linux-2.6.25-gentoo-r6. I _think_ it's got all the needed options set in the configuration. Can anybody suggest how to get my system to recognise my DVD drives? Thanks in advance! -- Alan Mackenzie (Nuremberg, Germany). -- gentoo-user@lists.gentoo.org mailing list

Do you mean
mount -t iso9660 /dev/hdc /cdrom

It means the directory entry /dev/hdc.

Can't resist what is on hd{a-f}

What kind of DVD writer do you have maybe it is sata or scsi, and it
wiil appear under /dev/srX or /dev/sgX. Or if you use the new libata
library in the kernel even IDE devices are under /dev/srX or /dev/sgX.

Maybe. Is that different?

OK.

Nothing on hd[abef], a DVD writer on hdc and a DVD reader on hdd. My PC
was built in 2001, and the 2 onboard IDE ports are ordinary IDE,
whereas the two IDE ports stuck on the side do UDMA66.
My kernel is an up to date linux-2.6.25-gentoo-r6. I _think_ it's got
all the needed options set in the configuration. Can anybody suggest

No, the box is no longer young, and contains no SATA or SCSI bits at all.
I'm just going away to see if I've got any /dev/s[gr]X on the box.
No, I've got no /dev/s[gr]X at all.
Could it be that the kernel has looked at hd[ab], found nothing there,
and therefore decided it's not worth the bother even looking at
hd[cd]?

Yeah, there is a space between -t and iso9660 :-) What kind of DVD writer do you have maybe it is sata or scsi, and it wiil appear under /dev/srX or /dev/sgX.

Hmm, maybe the output of `dmesg`, `lspci -v` and `ls -al /dev` could be helpful. Probably also your kernel configuration.
