Mine worked first time
Switch off N54L,plug sata end into hdd
attach power to hdd(am using a external molex type psu)
attach esata end to N54L
restart N54L
Works every time for me
IS your hdd working ok?can you feel it spin up?have you formatted or installed in administrative tasks-storage?
Yea brand new drive that works with my external caddy.
I have a molex -> 2x sata power for the hdd.
