Personal Video Database

Dear forum members,

When I want to make a movie master of video files on my external HDD, and thereby using the file directory list, the drive isn't recognized. Normally I'm using windows explorer and searching through the entire disc is possible. I don't have any clue, it's not visible in the list.

Details external HDD:
WD My Book Essential 2 TB 5.0 Gbps (USB 3.0) - [I'm using USB 2.0 at the moment, because the notebook has 2 USB 3.0 ports that are somehow broken.]
