- 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
- disks.
