Scan drive surfaces
The read only test performs a non-destructive
scan over the entire surface of each drive to
identify bad areas of the disk drives and determine
read performance. It may be run while data is
passing through the FastStream.
Running this test may negatively impact
performance. Once the Read-only test has
completed, system operation returns to normal.
