Query: Major design flaw

I've had this drive for a year now. I've used it with all permutations of PCs & Macs and laptops & desktops and FireWire & USB. For USB on both platforms and for FireWire on PCs, you'll need the power adapter, which is a poorly designed cheap-o part--it timidly plugs into the unit. The problem is that it disconnects frequently and unpredictably from the hard drive. Unfortunately for me, it did this while I was saving an important file, which, along with a few directories, were lost forever. They seem to have corrected this issue with their new disk drives, and I recommend you avoid this still overpriced drive.
