OK so I have two hard drives - 1TB (Windows, Installation of Applications ect.) and a 1.5TB File Storage (Movies, Games Music ect) so my torrent client saves downloads to my 1TB Hard drive i the Downloads Folder. When there done I move them to the Files Hard Drive. But when I do this windows 7 loses responsiveness and then if I wait long enough it fixes itself but the Files Hard Drive is gone. This has only recently started happening and I haven't made any hardware modifications in a while. Sorry if i forgot anything, just ask an I will answer. System Specs on left.
