Initializing a Logical Drive
Initialization is done to logical drives after they are created from a disk array. Initialization sets all data bits in the logical drive to zero. The action is useful because there may be residual data the logical drives left behind from earlier configurations. For this reason, Initialization is recommended for all new logical drives.
