RH 7.2 Mounting Issue
I just installed RH 7.2 and for some reason when I try to:
mount /mnt/cdrom I get an error saying: mount: /dev/cdrom is not a valid block device The Cd-Rom has a Cd inside of it, and for heavens sakes, I installed the distribution using it. The information refering to the Cd-Rom is in the /etc/fstab so the system has to have recognized it. Any suggestions? Thanks! |
Do you know which device your CD-ROM is on the system (/dev/hdb, /dev/hdc, etc...)? If so, just try to mount it using
Code:
mount /dev/hdX /mnt If you could post your /etc/fstab swomeone here should be able to give a hint or two as to how to get your cdrom mountable. |
check
ls -l /dev/cdrom which will tell you what the pretend device actually points to. to find more info about what hardware is known to your system, have a nose around /proc/ide/hdX cat everythign in sight, it's all plaintext, and you should be able to verify that the hard drive is properly located as an IDE deivce |
A cat named (none)
I cat'ed all of the files and for the one that was called "driver" all that was there was line saying:
(none) It seems I have a Matshita CR-581. That's about all the information I could get. Do you know how I could go around looking for the driver? Thanks! |
standard cdroms don't need drivers, jsut liek a harddrive doesn't need one. they are very standard devices, so a general integrated driver is used.
so, you should know where teh drive is, so mount /dev/hdX /mnt/cdrom or whatever... |

You might have a cdrom drive that is "blacklisted" in the ide-dma driver in the kernel. This happened to me and after three days I found out the problem (and how to fix it).
I had "(none)" in the /proc/ide/hdb/driver file. To fix it, turn off DMA on the cdrom drive, e.g. /sbin/hdparm -d0 /dev/hdb If this works, then the contents of the driver file should change immediately. Put it in /etc/rc.d/rc.local for it to happen automatically at bootup. Good luck! Ben |
