"
I've plugged my ADATA 64-gb card (which claims to be SDXC) into an HP netbook
with integrated SD slot and windows 7, and it reports the file system as FAT32."
But you didn't say whether your Adata, before plugging it in, had the original OEM
formatting, or whether it had been used in some other device which may have
been used to (re?)format it to FAT32 (mp3 player, digital camera, etc.).
The main thrust of your line of questioning seems to be, does the SXDC spec
strictlyrequire exFAT for SDXC of 64GB and up?
We could answer that if we had a copy of the SD Association's "File System Specification"
document of (near as I can tell) Version 3.01 or higher. (Neither you or I are The Finder,
so no answer thus far.)
Even then, I'd venture to theorize that the deciding factor is more what any devices'
manufacturer has set in their firmware, as to whether a device would read or instead
have problems with an SDXC 64GB and up formatted in FAT32...
Mmmm, random example, reportedly the HIFIMAN HM901 music player has no problem;
