Query: "Eeeeeeeeeeeee......"

At first, this drive seemed just what I was looking for. I plugged it in and It Just Worked. So I immediately set about copying a bunch of stuff from my unofficial backup system (a big pile of CD-R's) to my new drive.After about 20 minutes of this, a high-pitched "Eeeeeeeeeee" sound started coming from the drive. My wife noticed it too. So did our dog - the high pitch caused canine conniptions.I disconnected and powered off the drive. Blessed silence. I tried again after a couple of hours. Quiet at first, but soon enough "Eeeeeeeeeeeeee" once again.I spent a day or so wondering if I could put up with this over the long term, and decided against it. Back to Amazon it went, and my money was promptly refunded. I bought another drive from AcomData, 160gb, for the same price as this one, and now I'm a happy camper.Maybe I just got a bad apple; most of the other reviews on this seem positive.
