I recently bought an external USB 2.0 2.5" SATA enclosure for a 80GB hard drive I removed from my MBP when I installed a newer, larger hard drive. The enclosure works great, but I have one major problem with it- when I put my MBP to sleep, the external enclosure stays on, LED lit, and hard drive spinning inside of it. I had a different thread on this earlier that has run into a dead end. I learned from that that some external enclosures only sleep if they have some sort of hardware that allows them to. What is this piece of hardware called, so I know what to look for in an enclosure? Does anyone know how to make the enclosure and hard drive power down when the MBP goes to sleep?
