Because internal optical drives are typically designed for desktop computers, while duplicators are specifically used for copying or burning discs, the design and functionality of the two may be incompatible with each other in terms of hardware and software, and there is no guarantee that duplication operations can be performed correctly or achieve the expected performance of the optical drive.  The following products are not guaranteed to be compatible with duplicators:             DRW-24D5MT, DRW-24B1ST, RW-24B3ST, DRW-24F1ST, DRW-24F1MT, BW-16D1HT PRO, BW-16D1HT, BC-12D2HT.
