If the block rang was not algined, We tried to algined the range, then erase the block. So the block range erased should be less or equal to the block range sent. If error occured during erase procedure part of them will be erased. And use should resend the block rang to continue erase the reset of them.
Error number and zero number mean erase operation was failed.
