Bad Block Handling in
A method for handling low quality drives. The operation is performed
degraded mode
on both the logical drive in degraded mode or those that are being
rebuilt. If bad blocks should be encountered during Rebuild, Add
Drive, Host Write, or Regenerate Parity operation, the controller will
first attempt to reconstruct affected data and those irrecoverable bad
blocks are stated as bad and the controller return to host.
Users have the option to abandon data on the unrecoverable sectors
to continue rebuild in a degraded mode.
Low quality drive handling comes with transparent resetting of hung
hard drives.

recorded on drive media. The logical drives can still be accessed if
using different Galaxy RAID controllers/subsystems, e.g., drives
removed and installed in a different subsystem.

Now this feature comes with an option whether to restore the
previously saved password in case an administrator changed the
password some time before or simply forgets the previous password.
