Have this disk selected because my notebook was maxed out with movies and music from memory here. At first everything was stored as a backup to the WD and then "cleaned up" the laptop. After that I "MY BOOK" connected to my router and can now grab via WLAN from anywhere in all my movies and music collections. The whole has taken a while (were a total of nearly 1 TB of data), but was properly by installing ago, for me as a "normal user", simple and works.
