Had two of these over the past 2 years and both have failed with hardly any use. The first one caused me to lose quite a bit of items because I didn't make a disc copy of what I stored on it. How was I supposed to know I needed a back up for my back up? Ordered my second on in January 2008 and it died in a little over a year. Why did I order a second one? Should have learned from the first. Skip this item as a back up, it's a waste.
