Quick Disk Test
This test performs a non-destructive read/write on one block per
track on the disk. The test reads one block on each track, saves the
data, and proceeds to write and read four test patterns to the bytes
in the block. If the block is good, the saved data is written back to the
disk.
To run the Quick Disk Test:
1. Select the Quick Disk Test from the Device Tests menu.
– The power indicator blinks while the test is in progress.
– “Quick Disk Test/Test Passed” message displays if the test
passes and the power indicator turns on solid.
– “Quick Disk Test/Test Failed” message displays if the test
failed and the power indicator turns on solid.
2. Press Go, Return, or Stop to return to the Device Tests menu.

menu, press Return/Stop. To continue with the test, press Go.
