ATTO Technology FastStream VT, 5300 Scan drive surfaces, Verify storage, Select Verify Only

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.
