I don't know if you'll see this reply since it was so long ago, but once upon a time there was a company called Trace Mountain that sold diskette duplication equipment. These drives would duplicate any diskette in bulk at a rate of about 1 every 15-20 seconds. Formatting disks meant simply copying a disk that was already formatted. Unfortunately, the decline of diskette usage forced Trace nearly into bankruptcy, and now they no longer support these drives. They're still out there, though. I'm not sure where you'd find them.
