Here's a very good video on opening it: http://www.youtube.com/watch?v=-_2oMyoTB...

Western Digital 1 TB My Book USB 2.0 External Hard Drive used it put important things on it stored it the way it should be stored, go back to gather stuff (yes its been awhile) but that should not matter, … and the %#*@ thing wont even turn on.. no light on it nothing, can’t get anything off it, computer will not show it as being connected, because there is NO power going to it, (hence why the light isn’t coming on) paid for this got VERY little use for it and will NEVER buy from WD again.. so not happy with this .. i have lost everything now. thanks WD
