Write a disk image file to a floppy disk.

Equipment/Software Requirements

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


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



And follow the prompts. All arguments are case-insensitive.

If the source and destination drives are the same, RaWrite will ask the user to swap diskettes as required. Rawrite allocates a large buffer in RAM to reduce the number of disk swaps.

RaWrite may be aborted at any time by typing ^C or CTRL-Break.


RaWrite attempts to determine if the diskette is a 1.44M, 1.2M, 720K, or 360K diskette by reading sectors 18, 15, and 9 in that order. If the inserted diskette is not one of the these types, then RaWrite 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.
