Thanks for the responses so far, guys. Except for your second response, Murph. Ha ha.

Steve, I do have an eSATA connection, so we'll see how that goes. I couldn't get my current WD to work right with it. It didn't want to wake up after a period of inactivity. Of course, now it's doing the same thing when I'm connected via USB 2.0. It's also taking longer to prime itself when I turn it on--a worrying struggle--which is why I want to replace it as soon as possible.
