You may verify the status of storage which does not
belong to a RAID group (unattached 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.

Scanning drive surfaces: read only drive
test
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.
