Hello, (a) In my XPS-8930 tower, I unplugged the power cable and the data cable to the optical drive.  (b) Unplugging the power cable was very difficult and afterwards I could not plug it back into the drive.  (c) The pins in the socket in the drive are tiny and very difficult to align and after working with it for several hours I broke two of the pins.  (d) I would like to have an optical drive in this system.  (e) Solutions?
