[newbie] mounting drives

[mat rooney]

I've just upgraded to the latest version from RH 6.0
I'm having trouble getting the floppy drive and the cdrom mounted
Both of these worked perfectly under Red Hat
When the supermount option is used there is nothing in the directory
and when I try to mount by editing the fstab file I get the error
mount: /dev/hdc is not a valid block device.
please help
