I've just got a 128GB Sandisk microSD. It shows up fine on my phone, can save & copy media no problem. And if I put it in my VERY old ZTE Rio & plug that in my PC I can see it and copy media to & from it. But if I have it in my 640 & plug that into my PC all that shows in the directory is my 640's ROM; Twice!
I've googled after I finally gave up trying to work out why, & now I'm desperate enough to post here.
