 DDS - Disk Drive Summary Utility   Earl F. Glynn 04.07.1989

Утилита DDS выдает информацию о всех активных дисках (за исключением виртуальных): количество байт на сектор, секторов в кластере, количество кластеров, емкость диска и количество свободного пространства.
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.

DDS: Disk Drive Summary in Turbo Pascal by Earl F. Glynn Overland Park, KS Compuserve 73257,3527 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.
