When Gabriel and his "wife" are in Don's office copying files from his computer it shows them using connecting an external hard drive from a Commodore computer to Don's PC. The Commodore and IBM PC had incompatible operating systems so they would not have been able to make copies of the floppy disks on the Commodore disk drive. However, the IBM DOS had a copy disk command which would have allowed them to make copies of the floppy disks directly on Don's computer.
