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!
