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 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.

Disk Test/Clean

Warning: This test destroys all data on the disk and should not be attempted on a good disk. Also
note that this test may run approximately 1 1/2 hours depending on the disk size.
To run the Disk Test/Clean Test:
1.
Select Disk Test/Clean from the Device Tests menu.
"Files will be lost/Go or Stop?" message displays to warn the user that all contents on the disk

continue with the test, press Go.

periodically indicating the percentage of test completed and the number of bad blocks found.

pressing Return/Stop.

Once the test is complete, the power indicator turns on solid and a message displays.

"xxxx Bad Blocks/yyyyyy Usable" message displays if fewer than 2000 bad blocks are
detected. xxxx indicates the number of bad blocks and yyyyyy indicates the number of
usable blocks.
