Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Sandisk Ultra II, 2 Gb, SD works fine.
I also have a mystery one called "LX series" 16 Gb, SDHC, Class 10. It's fine too, though it could be a while before the Maxi collects that much data.

Maybe the problem with the SD cards is not the cards themselves but an issue with the Maximite. When I built the WIB, i had the same problems that some of you guys are having with the Maximite. It came down to the 3.3v regulator output voltage being slightly low. I changed the resister bias and to give me a voltage as close to 3.3v as possible. Some SD cards have a very fine voltage tolerance (window).
I just thought I'd share this experience with you in case it may help.
Its easier to ask forgiveness than to seek permission!
