The variable LockOnReset should be set to PowerCycle to ensure that the data bands will be locked if power is lost This scenario occurs if the drive is removed from its cabinet The drive will not honor any data read or write reguests until the bands have been unlocked This prevents the user data from being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system When the drive is shipped from the factory the firmware download port is locked and the drive will reject any attempt to download new firmware The drive owner must use the SID credential to unlock the firmware down load port before firmware updates will be accepted 9 5 Data bands When shipped from the factory the drive is configured with a single data band called Band O also known as the Global Data Band which comprises LBA O through LBA max The host may allocate Band1 by specifying a start LBA and an LBA range The real estate for this band is taken from the Global Band An additional 14 Data Bands may be defined in a similar way Band2 through Band15 but before these bands can be allocated LBA space they must first be individually enabled using the EraseMaster password Data bands cannot overlap but they can be seguential with one band ending at LBA x and the next beginning at LBA x 1 Each data band has its own drive generated encryption key and its own user supplied password The host may change
