I still newbe in linux. Currently i using linux debian but i really do no how to configure the cd rom drive. After insert the cd it can't be eject i really out of idea. Any idea?

Unmount it first with the umount command:

# umount /dev/cdrom

Notes:

1. You don't type the #, that's just the prompt when you are root. To become root, type su and then enter your root password when prompted.

2. /dev/cdrom might not correspond to your CD ROM drive, replace it with whatever is correct for your machine. If in doubt, post a copy of your /etc/fstab here and we can tell you. You can open the file with any text editor, or type "cat /etc/fstab" in a terminal window and then copy the output.

HTH.

Or make sure nothing is accessing the cdrom and simply type eject at a terminal to eject the cdrom.

I didn't know you could do that, oops.

Here i attach my fstab config file should i need to change anything here? It's seems ok for me.....

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda4 / ext3 defaults,errors=remount-ro 0 1
/dev/hda2 /boot ext2 defaults 0 2
/dev/hda3 none swap sw 0 0
/dev/hdc /media/cdrom iso9660 ro,user,noauto 0 0
/dev/fd0 /media/floppy auto rw,user,noauto 0 0
/dev/hda1 /mnt/c ntfs ro,umask=0222 0 0
/dev/hdb1 /mnt/d vfat rw,umask=0222 0 0

You don't need to change anything, but to unmount your CD-ROM drive, you'd do

# umount /dev/hdc

Thx
