4GB Microdrive Serial Number Check

[HeartWare]

I read the microdrive review and to reiterate what to watch out for when dealing with the 4BG Hitachi OEM is that the last 3 digits should be either "41C", "42B", or "43B" for digital camera compatability. And to stay away from "44C" as it does not work. However, I have seen higher number such as "45C" & "46C". My question is: Are all other numbers OK and just stay away from "44C" or should you stay below "44C" as all higher number do not work?
