OK BT there are 2 ways to go about it...
First: Go to System Information in Start > Accessories > System Tools... Once here select Components on the left hand Window then choose CD-ROM. Near the bottom of the list that appears on the right will be a the drive ID, this will be the drives name etc, there will be a line of _____________ which should then be followed by the firmware revision... phew!
An easier way is to load up something like clone or nero and check there
