I know there is a lot of questions on mounting cd-roms, but I am still stuck. PLEASE help me, as I am a complete newbie.

I'm running red hat 7.2. My hardware browser says the DVD is hdc. And it works in windows.

Ok, when I try to load anything from my cd-rom, I get the error message "not a valid block device"

When I input "dmesg|grep CD" i get:-
hdc: CREATIVE DVD-ROM DVD6240E, ATAPI CD/DVD-rom drive

but when I do "dmesg|grep -i ide" i get:-

BIOS-provided phsical RAM map:
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz pci bus speed for PIO modes; overide with idebus=xx

Now I don't know why some entries a there a couple of times. I don't know if the reason is that the drive is a DVD drive, but I just want to get it to work as a CD-ROM first. I can watch DVD's on my windows98 installation. I have LINUX on my cecond hard drive, hdd. When I had just win98, my second hard drive was made a slave. Do I have to put the jumpers bac to make it not a slave? does this matter, because LINUX is reading it ok.

here is my fstab aswell. any help will be great. Thanks

Thanks in advance, Steven.

test

there was a bug in RH 7.2 that may (or may not) be causing this.
at the root prompt enter depmod -ae, then try to use your cdrom.

As root type this command:

depmod -ae

Then try to mount your cd.

This has been mentioned alot, here is a link to post rshaw made a long time ago cause this was such a common question: http://www.linuxquestions.org/questi...&threadid=8460

[edited] Haha.. and rshaw beat me to it.. [/edited]

Thanks for the replies, but I found a fix to the problem myself. All I had to do was add the line:- "alias cdrom /dev/cdrom" in my /etc/modules.conf file. I don't know how this worked, but it did, and I can now play cd-roms. Thanks again for your time to reply.
Reid.

I said in my original post I was running Red Hat Linux 7.3. I'm not it's 7.2!!! Sorry for the confusion.
