Compaq Infortrend Manuale Utente

Media Scan is used to examine drives and is able to detect the
presence of bad blocks.  If any data blocks have not been properly
committed, data from those blocks are automatically recalculated,
retrieved and stored onto undamaged sectors. If bad blocks are
encountered on yet another drive during the rebuild process, the
block LBA (Logical Block Address) of those bad blocks will be
shown.  If rebuild is carried out under this situation, rebuild will
continue with he unaffected sectors, salvaging a majority of the
stored data.

From the Main Menu, press ▼ or ▲ to
select "View and Edit Logical Drives".

have more than one logical drive, use
the  ▼ or ▲ keys to select the logical
drive you want to scan; and then press
ENT.

Press  ▼ or ▲ to select "Media Scan"
and then press ENT.

Press  ENT again to display the first

and use arrow keys to select an option.
Press  ENT to confirm the change on

Use arrow keys to move one level
down to another option, “Iteration

many times the scan is performed on
the logical drive. If set to the
continuous, the scan will run in the
background continuously until it is
stopped by user.

Press ENT on your option to confirm.
