This computer system only has a 1 cd drive, a CD-RW drive. The Knoppix cd boots up fine. But when I go to remove the cd to insert a blank cd to burn, the drive will not open. If I go to the burning software and right click on the burner on the left side and choose Eject, I get an error message saying that I cannot unmount the drive.

So how can I rescue files off of this computer and burn them onto a cd if I cannot access the drive itself while running Knoppix? Any help would be helpful. Thanks.
