I don't understand your problem
 

If Micro Studio sees your internal Plex, I guess I don't understand what the problem is.
Micro Studio only needs one CD-R to operate, you read from your internal CD-R to hard drive, then write from your hard drive to the internal CD-R.
This program has no disc at once option, and only needs to see one drive to back up CD+G discs, or to make custom discs.

Josh,
This means that you need a special ASPI driver to support the USB drive. Please email me at support@mtu.com so that I can send you this file.
