The ATTO FastStream initialize and verify feature discovers and remaps bad sectors on drives, providing reliable
media for your RAID groups.
Before creating any RAID group you should initialize
and verify the drives you want in the RAID group to
ensure drive integrity. When selected, the FastStream
writes a pattern to the entire drive, verifying the drive's
readiness and reliability.
You may, however, follow the procedure
initial configuration on page 9 to set up a Virtual Tape
Library, then initialize the drives in the VTL before
using them for data using the procedure outlined in
After creating RAID groups
During initialization and verification, the FastStream
collects performance measurements. Performance
data is available once initialization begins. You may
view it from the Drive Performance and Health
page accessible from the Diagnostics menu. This
performance data is lost when the appliance is
powered off.
You may check drive integrity after you have created
RAID groups on drives in RAID groups or drives which

Selecting Drive Initialization causes all
previous storage data on the drive to be
erased. Make sure all of your information is
backed up before initializing drives.
The read-only drive test performs a non-destructive
scan over the entire surface of each drive to identify
bad areas of 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.
