- Yes and no.
-
- Yes, the high speed of DiskRW compared to other programs for the
- same purpose comes (partly) from using this trick.
-
- No, DiskRW is not a formatting program, is a program to copy disks,
- to store all contents of a disk in an image file and to write such
- files back to disks.
-
- It can also format the destination disk, but this format will be
- a standard format. I find it better to have disks formatted in the
- usual way and have intelligent programs to access them faster.
- DiskRW is a fast way to copy disks, a fast file copier will come soon.

-
- That's why DiskRW has to be initialized on every machine.
-
- By the way: on MS-DOS the speedup is more like 25-50%, I never
- observed 75%.
