Lol! Am just in the same atm...
Windows doesn't format it, insists in extFAT.
Linux only wants to format 32GB.
Note formats it flawlessly in a few seconds
I do have a hard time copying files over... last I tried (with the card plugged in on an usb adaptor to the pc) it copied until reaching the last 16GB, then it failed. So far so good. The card showed 16GB available, but couldn't put anything on it anymore.
Thus I went and deleted everything (yes, hidden files, too). And guess what? It still showed 16GB used...
This thing is weird... Doing a final try now, with the card in the phone, mounted on the pc, copying over... I'll report back in a few hours, ugh...
