UNIX for Dummies Questions & Answers

I have successfully installed redhat linux in my PC.
But when i am trying to mount cdrom with the command "mount /dev/sda1 /mnt/cdrom" I am getting the following error
"Unknown device /dev/sda1".

Can anyone help me in this regard.

cheers

I'm by no means an expert in Red Hat, but to mee the "/dev/sda1" looks suspicious. "/dev/sda1" should designate the first partition on the first ID harddisk, the CD-ROM should be /dev/cd0 or /dev/cdrom AFAIK. Hence the following command should work:

mount /dev/cd0 /mount/cdrom

I hope this helps.

I must agree with bakunin, if it is a recent version of RedHat than there should be a link /dev/cdrom. you should be able to mount this device to a directory (if you insert a disk) with :
mount /dev/cdrom /mnt (or whatever).

if it is an older version of RedHat (or an other distro) and the link does not exist you can figure out what the device is by looking in the boot messages with dmesg and look for the string cd or CD:

try dmesg | grep -i cdrom it most show some device
