DDS: Disk Drive Summary in Turbo Pascal


Earl F. Glynn

DDS shows a disk drive summary of all active drives, including bytes/sector,
sectors/cluster, number of clusters, bytes capacity, bytes available,
and working directory. SUBSTituted "virtual" drives are not shown.

Information about the Disk Parameter Block and what I have termed the
"Drive Array" was found in the public domain program SYSID.PAS by
Steve Grant, Long Beach, CA. I prefer to use RECORDs and pointers to
access this information instead of the MEM and MEMW Turbo Pascal "arrays".

DDS does not work well if logical drives A and B are both active and are
the same physical drive. The DOS prompt(s) may interfere with the output.

DDS is very useful on machines with DOS 3.3 and large disk drives. For
example, the IBM Model 80-111 has hard drives C, D, E and F under DOS 3.3.
DDS will quickly summarize information about all drives, including RAM
