5.9.6 Media Scan
Media Scan is used to examine drives and detect the presence of bad blocks. If any data
blocks have not been properly committed, data from those blocks are automatically recalcu-
lated, retrieved, rewritten or 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 listed. If rebuild is carried out in this situation, rebuild will continue
with the unaffected sectors, salvaging a majority of the stored data.
From the Main Menu, press the up or down arrow keys to select "View and Edit Logical
Drives".
The first logical drive displays. If you have more than one logical drive, use the up or down
keys to select the logical drive you want to scan, and then press ENT.
Press the up or down arrow keys to select "Media Scan" and then press ENT.
Press ENT again to display the first configuration option, “Priority.” Press ENT on it and use
arrow keys to select an option. Press ENT to confirm the change on priority level.
Use arrow keys to move one level down to another option, “Iteration Count”. This option
determines how many times the scan is performed on the logical drive. If set to “Continuous,”
the scan will run in the background continuously until it is stopped by user.
If Media Scan continuously runs in the background, considerable system resources will be
consumed.
Press ENT on your option to confirm.
Press ENT for two seconds to display the confirm message, then press ENT to start scanning
the array.
