I’ve already done that. Didn’t make the slightest bit of difference.
When I plug my USB 3.0 external hard drive into the USB 3.0 port the SanDisk Extreme was in it works perfectly. Take it out and put the SanDisk back in … nothing.
Clearly the problem is with the SanDisk Extreme and it’s USB 3.0 compatability. (As I mentioned above, when it is plugged into a USB 2.0 port it works just fine).
