Hi, I am new to this forum, and my first impression is that no one replies to anything, so it does not appear to be helping anyone. My screen goes blank after about 20 minutes and then I need to reboot, and rebooting works, but there is no evidence that it even attempted to do anything. And thus I am in a vicious circle. But my main problem is that no matter what USB device it put in, or which partition I note for it to use, it always fails the amount of space calculation. Always fails it no matter what. Is there no support personnel at this company to answer forum questions? Rob
