My 2.0TB “My Book Essential” external HD was working fine for a while, but lately it only shows up connected for a short time after plugging it into the power outlet. It stays connected long enough to begin a back-up process, but shortly disconnects and gives me an error window saying the drive was ejected improperly. I purchased the drive in Feb of 2011 and connect it up to my Mac Desk Top running Leopard. I’ve since upgrades to Snow Leopard. I also back up a Mac pro with the same operating system and I’m having the same problem.
