How to find a 9504 by LOT Number on the 360 Packaging Label
* 11XXX All 0225
* 104XX Mix of 9504 and 0225. Mostly 0225. High Probability that a 9504 is a mislabeled 0225
* 103XX Mix of 9504 and 0225 - mostly 9504
* 102XX All 9504
* 101XX All 9504
* 104X All 9504
Another method is by the serial number on the label (thanks to kiwi1hu). The 4th Digital on the end can also give an indication as to what the drive is (again not 100% but results have shown a very high probability - post your LOT# and Serial# results too)
* 2: 9504
* 3: 0225
