SD Card Compatability

Hello all, so I've been playing the fat16 library, so far it's been very useful, I've tried 3 types of SD card with varied results, full size 4 gig SDHC didn't work, it's not supported but was worth trying full size 512mb Toshiba, was recognised as present but just returned rubbish. MicroSD 2gb Sandisk in full size adapter works perfectly.

Does anyone else have brand / size / capacity info they have been successful in using?

Just started playing with SD cards so bought a few kingston 512mb mini sd cards with adaptors to fit my full size sd card adapter from ebay. One of the cheap voltage divider for voltage reduction types. Works well so far.
