Equipment/Software Requirements

  • PC/XT/AT or 100% compatible with at least 256 Kbytes of RAM and a floppy drive
  • MS-DOS version 3.21 or greater
  • A formatted diskette

This program uses well-documented generic low-level DOS and BIOS functions. It should run on nearly every PC in existence. PS/2's should be able to run RaWrite3 but this has not been tested.

Caveat

This program will write ANY disk file to a diskette, overwriting any previous information that may have been present. If you wish to re-use a diskette that has been written by RaWrite3 then that diskette will probably need to be reformatted; all MS-DOS specific information will have been erased.

Usage

Type at the prompt:

C:\> RAWRITE3

and follow the instructions. All arguments are case-insensitive. If the source and destination drives are the same, RaWrite3 will ask the user to swap diskettes as required. RaWrite3 allocates a large buffer in RAM to reduce the number of disk swaps. RaWrite3 may be aborted at any time by typing Ctrl-C or Ctrl-Break.

Errors

RaWrite3 attempts to determine if the diskette is a 1.44 or 1.2 Mbytes, 720 or 360 Kbytes diskette by reading sectors 18, 15, and 9 in that order. If the inserted diskette is not one of these types, then RaWrite3 will abort with an error message. Errors such as write protect, door open, bad disk, bad sector, etc. cause a program abort with a short error message.
