Hello....My cdrom has been working fine up until this morning for some reason....If I click on the Icon to mount it, it gives me an error saying:

"could not mount device. Mount: special device /dev/cdrom does not exist"

I ran dmesg.....there is a line that says it detects it:

hdc: QSI DVD-ROM SDR-081, ATAPI CD/DVD-ROM drive

It is a combo dvd/cdrom drive.....

Not sure why it suddenly will not mount.....anything to do with /etc/modules? fstab?.....please help! bob58
