REFORM16.ZIP - DOS disk defragmenter with Turbo Pascal v5.0 source
Following is my latest tweak (v1.60) to the PCDOS-specific version of
Jos Wennmacker's REFORMAT disk defragmenter.
The earlier (v1.50) version expanded capability to include
large (30+ Mb) winchesters.
This version has been rewritten for Turbo Pascal v5.0, and works just
fine with my PC-DOS v3.1, a Seagate ST225 20Mb hard disk and an ancient
CMI 10-megger.
I have no way of testing its compatibility with larger disks, or with
DOS versions above v3.1. The original author coded the program to abort
if DOS versions above 3.1 were encountered. I've changed that to provide
the user with a warning message and the capability to continue if he or she
so desires.
I've resisted any further attempts to speed up the reformat (such as
buffering direct disk read/writes) since I'm not quite sure what I might
break! However speed is adequate for the purpose: A recent reformat of
my 20MB hard disk (with approx 750 clusters to relocate) took 22 minutes.
Incompatibilities could come from (1) use of several undocumented
DOS calls, and (2) direct video memory write.
Full honor and glory to the original author:
