I have recently tried moving around items on my HD to organize it. When I start moving more items it seems to freeze up, click once then power down a bit before powering back up.

I have been running a diagnostic on it for a good hour now, and it has been running fine the whole time. Any clues? Thanks guys! Oh, it is a Western Digital Mybook Wanna kill these ads? We can help!
