Quick Disk Test

This is a one minute test which performs a non-destructive write/read
on one block per track on the disk. It tests the printer-to-disk
communications, and the disk hardware and circuitry, but does only
incidental testing of the disk surface itself.
The Quick Disk Test does not destroy data on the disk; existing data is
read and stored prior to the testing of each track, and then rewritten
after the track is tested.
