SEEK_BEGINNING takes you to the beginning of the log . .The pointers get automatically incremented when you are doing LogWrite.append, annd when you are doing LogRead.read. So if you just want the last piece of data stored then you should move the pointer back by that amount (using .seek )and then say Read.
