Recently swapped out HDD for a SSD as the main drive. Fresh install of 8.1. Copied a few program folders over to the SSD. Haven't tried all, but what I have work. Formatted old HDD externally, showed unallocated full amount. Assigned letter "F" to it. Placed it internal & it didn't show up until after a few reboots. Didn't do anything with it last night. Today, I want to start copying a couple of programs from the SSD back to it & then latter some from a back up on another external drive. When I left click on the "F" drive it will open. When I right click or click on any of the up top tabs, it hangs with a "not responding" note. I tried to go into disk management but it wouldn't open. I then tried device manager, same thing. Now if I right click on the start button nothing pops up. I did get an error message while typing this but couldn't access the snipping tool to copy until I cleared the message. I will do it again & copy. Not sure what the deal is, but it's aggravating!
