Compaq Infortrend manual Media Scan

Media Scan

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".

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