Cons: Bulky, heavy, not easy to store my photos and then work remotely.

Overall Review: The reason I gave this My Book Duo one egg is because I trusted my 155K Lightroom photos to this drive, storing them on this drive since my hard drive could not accommodate the 585GB. I had the two drives set up as mirrored...should be safe, right? But what if the case goes bad, which happened to me. The fan kept going on, and on, and I could not access my photos. I unplugged, and re-plugged, and still the fan kept going. I called WD support, the tech accessed my Mac and he also saw that I could not access the drive. So the resolution is to return it (still under warranty, thankfully), but I have to pay to ship it back! I finally got my photos off by plugging and unplugging, waiting hours between, until the fan did not go on. So you can imagine how long it took! I mailed it back today and supposedly I'm getting a new one, but will I trust it? The jury is still out.
