Device Tests
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.
