I installed Fedora Core 3 on my computer which has 1 CDRW drive & 1 DVDROM drive.
Both drives work in Windows.
The DVDROM drive is used to install FC3 with FC3 cdrom.
Logged in as root, the drives are not found in /dev.
i.e. cd* and dvd* are not found.

Why?

# ls -l /dev/cd*
ls: /dev/cd*: No such file or directory

# ls -l /dev/dvd*
ls: /dev/dvd*: No such file or directory

# ls /dev

They will be either hdb, hdc or hdd. You should be able to tell from dmesg:
dmesg | grep ^hd

They are hdc & hdd.
Thank you!
