Often they advertise 32GB but they're compatible with larger, just not officially supported. For example http://www.motorola.com/us/moto-g-pdp-1/Moto-G/moto-g-pdp.ht... only advertises 32GB but I put a 64GB in it out of the box and it works.

i can't lookup the debian bugs now... but beware. it will work only until you write a not so rare byte combination there using the SDHC interface. after that happens, the sdxc controller will just crap on every data read and you will have a tiny brick.

Ohhh... THAT explains a lot... Might explain why cards dying in phones is so common.

If you could find that bug for me it'd be much appreciated.

SDHC vs SDXC I believe. SDHC only goes up to 32GB.

Interesting. Thanks. From some brief reading on wikipedia, I wonder if they chose SDHC to avoid any (patent) issues with the exFAT file system.

Kinda seems like a shame. 32 GB is quite a lot, but for HD video, it seems like it could fill up quickly.
