My trusty old 16GB micro SD card that has been with me through 4 phones is finally full. So I figured no biggie; I'll just buy a new (64GB) card, copy all the files down to my PC (which has no card reader, just USB ports), then up to the new card.
The issue I'm having is that copy step. I have the card in a Note4, connected to a Windows 8 PC via USB. I can see the card, but if I just try to drag-and-drop copy folders to my PC, it invariably ends with a dialog saying:
"A device attached to the system is not functioning".
I'm guessing its on largeish files, as I've noticed .mp4's in particular will just cause Windows explorer to go out to lunch and never come back when I try to copy them individually.
It seems like this ought to be the simplest thing in the world to do. What am I missing?

directory will be inaccessible and usually not exposed, so you couldn't copy it (which would make you lose apps moved to SD). I'm not 100% sure if there are other places where the same applies (though I'm not aware of any). If you've not moved any App2SD, you could of course try: if it doesn't work out, you can always (temporarily) switch back to your old card.
