So I just got the Runcore SSD for my rev. A ($200) And it doesn't work. Right specs (the ZIF is a bit loose-there's two types of ZIFs -if you can believe this) It should work....I think. It works in other devices so either it's a firmware thing of a ZIF thing. Thing is, I went through this same thing with the Mtron 32GB SSD. It also was not detected (exact same scenario ). Others also were having problems with the Mtron and apparently there was a firmware update at one point (but I had sold mine already) So i'm waiting for others experiences with this. (these are hard to come by as only one place in the US sells them (MyDigitalDiscount.com) as far as I know and they are backordered until mid Feb.
