Oh gawd, I remember that.... Yeah, that's why I stayed away from EEprom.

There is a tutorial about formatting the SD card. It looks like normal memory formatting procedures. Personally, I haven't done that with any of my camera's cards and they seem to work just fine in my Macs, PCs, and Linux machines; kind of like USB memory sticks just work. A few years ago I remember having to format those for specific computers.

I think what I'm going to do is buy two of those Spark Fun CAN bus boards, the one with an SD card connector. They can connect to a couple of Linduinos I have for the BMS. With this I can mess with CAN and data logging with an SD card.
