i have installed mandrake with no prob, then i went to use a cdrom (i have two of them on my comp) and the disc wouldnt stop spinning and it made the whole computer slow down. i couldnt get the disc out. the other drive works similarly, but i can get the disc out when i want. in my fstab, everything referring to cdroms and floppy has "none" before the rest of the line. what should i do?

Post back some more info. First do an ls -l /dev | grep cdrom and post the output. Also post your /etc/fstab file.

CD-ROMs cannot be ejected while they are mounted. You need to unmount it using the umount command - take note that it's not actually called "unmount"!

im sorry, im a complete newb/idiot to linux.

lr-xr-xr-x 1 root root 13 Jan 15 11:58 cdrom -> cdroms/cdrom0
lr-xr-xr-x 1 root root 13 Jan 15 11:58 cdrom0 -> cdroms/cdrom0
lr-xr-xr-x 1 root root 13 Jan 15 11:58 cdrom1 -> cdroms/cdrom1

fstab:

/dev/sda1 /mnt/win_c2 ntfs iocharset=iso8859-1,umask=0,ro 0 0
none /proc proc defaults 0 0
/dev/hda6 swap swap defaults 0 0

part of the problem is i couldnt unmount it if i wanted to. everything completely slows down while the one cdrom is working, and it wont do anything. just spin all night if i left it alone.

UPDATE:

now when i try to mount the cdrom, i get the following error

mount: wrong fs type, bad option, bad superblock on /dev/scd1,
or too many mounted file systems

Could be a supermount problem. With supermount you do not need to use the mount / umount command. As soon as you access the CD or floppy the disk is mounted. You might get errors when using the mountt command because the system thinks the CD is already mounted due to supermount.

After a certain period of inactivity the media is automatically unmounted. You still need to close and applications that are accessing the drive before ejecting.

supermount has its problems on some systems. Try disabling supermount.
supermount -i disable

See man pages for supermount for additional info.

After disabling supermount you will need to manually mount / umount removable media.

i disabled the supermount like you said and restarted so i would be positive there no errors, but now i get this one:

Could not mount device.
The reported error was:
/dev/scd1: Input/output error
mount: I could not determine the filesystem type, and none was specified

I am somewhat of a newbie and had about the same problem. I used the command usermount. It It brought up a nice little deal that showed all mountable devices. You select the one you want and then can mount or unmount it all you want. Maybe this will help somebody out there, it was the only thing that worked for me.

thanx, ill see if it works

How are your drives connected to your PC i.e. which one is master / slave on what controller etc.

Can you post the output of
ls -l /dev/scd1
