my 'my book essential' WD external 2TB hardrive is not powering on at all, it was working fine, i could watch movies, transfer files etc, but now, nothing, LED light does not come on, computer doesnt read anything, no power at all. i did delete a sub folder which i didnt know what it was or how it was there, since then, nothing. ive tried different power outlets, connecting to different computers, tvs but still nothing... anyone know if this can be remedied? or should i consider it dead? if so, how & where can i retrieve the data?
