I have a Thermaltake BlackX dock. It has both esata and usb2. I use the esata connection. In the past, the dock would sleep the hard drive after being idle for a while, now it does not. I have not done anything to the dock or the drive. The only thing that's different is the laptop that the dock is connected to. I had to format and reinstall Win7 in the laptop. Since summer is approaching, I would like to avoid having my hard drive running hot. Is there something in the power settings or bios or whatever that can fix this?
