I have a brand new dvd/cd drive on an Ubuntu 9.04 computer.

When it tries to mount the drive it completely freezes up Ubuntu. Absolutely no response to mouse or keyboard and the only thing that works is a hard reboot and removing the disk (or else it just repeats the process next time).

I don't have any idea how to trouble shoot this. The drive powers on and spins up so I don't believe it is power to the drive and the software crashes when it tries to mount. Sometimes it will get as far as listing the drive, with the inserted disks correct name in "Places".

Any ideas? What should I even look at?
