I'm doing a new product that will have an embedded microSD card.  In
this case the user can change the card during product setup.

Are there 32GB or smaller cards with other than 512 byte sectors?

I can easily specify the card to be 32GB or less with a FAT format, but
I'm worried some cards may have different sector sizes.  Currently my
code is only works with 512 byte sectors and allowing for up to 4k would
put a serious crimp in available RAM.
