Query: Great Until It Fails! :(

Bought this drive to back up my data on my MacBook--bought it because of the Seagate name. It's nice drive with a sturdy, if somewhat bulky, plastic enclosure, dual firewire 400 ports and one USB 2.0 port, an combo on/off/backup button on the front. Comes with thick cables and a power adapter.The drive worked fine for six months, but then failed. It powers on and spins up, but will not respond to the power button and won't mount--just makes a spinning sound with occasional pauses, so none of my recovery software can see it.The drive has a power-saving mode that you can not disable--goes to sleep after 10 minutes or so. Unfortunately, the power light goes off too so you can't tell if it's still running, then it takes a few seconds to come back on when you try to access the drive. Good for the environment, bad for my workflow.Guess I need a back-up for my back-up. :(
