Should I use metadata 1.2 ? If you use 1.2 you will lose data. If you use 1.0 you will not. With 0.90 and 1.0 the data starts at the start of each device. so 1.0 will see the same data as 0.90 would. With 1.2 there is some metadata first and the start starts later, so if you use that the data will appear in the wrong place.
