Here is information about FCOPY, a fast, crude, diskette 
format-and-copy program.

FCOPY operates on the IBM Personal Computer.  It requires,
  1) an IBM PC or equivalent
  2) 256 K memory or more
  3) two diskette drives
  4) DOS 1.10
  
FCOPY was written to provide a more expedient means of 
copying diskettes than the DISKCOPY program that is 
supplied with DOS.  FCOPY is not a polished or flexible 
program -- it was created for private use, and therefore is 
rather crude.  For example, it only copies the PC's lowest-
common-denominator diskette format: singled sided, 8-track, 
160 KB format; it uses absolute memory locates from 95K to 
256K; and so forth.  

WARNING NOTE: Simply because of its particular use of memory, 
FCOPY requires the use of DOS versions 1.00 or 1.10, and not 
2.00 or above.

FCOPY is distributed free, as-is, for those who can make 
use of it.  Source code (Pascal and assembler) is included, 
so that any one with the necessary skills can modify it.

FCOPY works in the following way:

  * it begins by reading a master diskette into memory, 
    from drive A.
    
  * then it proceeds to format and copy diskettes, 
    alternating between drives A and B.
    
  * FCOPY operates continuously, for maximum speed; when it 
    is finished with one diskette, it begins with the next 
    diskette in the opposite drive.  
    
  * while FCOPY is formatting and copying on one drive, the 
    other drive can be unloaded and reloaded, ready for the 
    next copy.
    
  * if a diskette is not ready in a drive when FCOPY starts 
    trying to use it, FCOPY will continue trying until a 
    diskette is ready.
    
  * if FCOPY encounters any errors, it passes on to the 
    next diskette, without any second tries.
    
  * you can instruct FCOPY to pause at the end of the 
    current diskette, by pressing the Esc key.

  * FCOPY will produce formatted copies in about 30 seconds each.
