                 The strata devices do not support unlocking an 
                 individual block. Instead it is necassary to unlock
                 all the blocks in one operation and then lock all those
                 blocks that should be blocked. To do this we need an array
                 containing the current status of the blocks. This controls the 
                 size of that array."
