+ * 04h - name (12 byte)
+ * space for partiton header = 16 byte
+ *
+ * Log Header
+ * 10h - offset ( 2 byte) from Partition Header to Data Section
+ * 12h - flags ( 2 byte) control flags
+ * 14h - pointer ( 4 byte) pointer to first free byte in Data Section
+ * relative to the beginning of the data section
+ * 18h - zero ( 32 byte) reserved as stack for four 64 bit register
+ * 38h - reserved ( 8 byte) reserved for 64 bit CRC (not implemented yet)
+ * space for header = 64 byte
+ * Data Section
+ * 40h - cyclic data
