I too bought a 64GB SD card and it appeared to work straight out of the package. However, I made the mistake of loading stuff off my laptop on to the card. This I am told by an assistant in John Lewis is why the card will now not mount. I don't know where he got this info from. I have now bought one of those gizmos that enable a USB drive to be connected to the tab. Stuff loads OK to the card by this route, but still the card will not mount. The same person in John Lewis now tells me I must now format the card. All the foregoing is, apparently, to do with anti-piracy. Shoot me now.
