no /dev/hdc or /dev/cdrom

Heres a weird one- on a fresh install of Mandrake 9.0 , I cannot mount /mnt/cdrom- I get an input/output error. fstab shows /dev/hdc
When I cd /dev there is no hdc or cdrom listed as devices.
I try 'mount -t auto /dev/hdc /mnt/cdrom' and get an error message
" device does not exist", heres the weird part, I cd/dev again and hdc and cdrom are there and I can mount cdrom. After a reboot the same problem happens.

The output from dmesg and lsmod and cat /proc/filesystems would help.

I checked the logs and they didn't help, but you gave me a clue with lsmod. Apparently when I
'mount -t auto /dev/hdc /mnt/cdrom' 2 modules load, "ide-cd" & "cdrom". I have devfs installed and I would think they would load automatically.
I put that "mount.....' command in /etc/rc.d/rc.local and now it boots up with the modules installed, but I would still like to know the reason why. It's probably some kernal module configuration, I will dig a little deeper.
Thanks for the hint

I wanted to see the output from dmesg to see if the kernel detects your cdrom drive and dev entry. tell me what dmesg | grep CD gives.
