I have a T420s and I have mounted a WD 760 GB Scorpio Black @ 7200rpm in a Caddy. The drive is recognised, everything is ok, except one thing: from time to time (at a freqency of 10 to 30 minute) the hdd enters in sleep mode (I can hear the sound of hdd heads retracting) just for a moment.
I wonder if this is normal, becuase I have never had a hdd in a caddy and I know that the hdd is working perfectly.
The laptop is powered by a 65wats power adapter and stays in a docking station.
Can anyone help me on this?
