Hello,
I haven't tested any larger capasity cards with my Pi, but I have done
so with a digital music player I have, which needs cards formatted with
FAT32. Currently it is using both a 128GB and a 200GB card, both
properly formatted, and it works great. When it works there, I can
hardly think it won't work just as fine on the Pi, too.
In addition to using Linux to format a card with FAT32, there are also
freeware tools for Windows to handle that task.
Best regards

As I understand it, there is little, if any, electronic difference
between SDHC and SDXC cards, and even devices advertised as only
supporting cards up to 32GB have no problem reading larger cards that
are properly formatted.
What is an issue is that many cards 64GB and larger come preformatted
with Microsoft's proprietary xFAT filesystem, which has poor to
non-existent support outside of Windows and many devices advertised as
having a limit of 32GB don't know how to format larger cards. For
example, the 256GB card I have in my Blaze ET came from the factory
formatted xFAT, and the Blaze couldn't identify the card at all, and
the Blaze's own SD formatting utility still can't detect the card, but
it worked just fine after using my Desktop Linux PC to format it to
FAT32, and I went through the same experience with the 64GB card the
256GB card replaced.
Of course, you'll be formatting the microSD regardless(writing an
image will overwrite whatever is already on the card), so no need to
manually format the card to something the Pi can read.
That said, I've never actually tested a 64GB card with the Pi(the
aforementioned SDXC cards were full-sized and all my microSDs are 32GB
or smaller).
