Quick Disk Test
This test performs a non-destructive write/read on one block per track
on the disk. The test will read one block on each track, save the data,
and proceed to write and read four test patterns to the bytes in the
block. If the block is good then the saved data will be written back out to
the disk.
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.
