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.

Verify storage

Verify the status of attached storage to identify

drive issues after drives have been initialized. If

the verify operation detects an error, the

FastStream tries to re initialize the drive, erasing

information stored on the drive. Be sure to back

up data before performing verification.
