Customer service plug: I use a Drobo from Data Robotics for my backup drive (and more general storage than I should). A big power failure the other day fried it's controller, despite being on a big UPS. (Did I mention I really hate Sothern California Edison?)
The Drobo people overnighted me a new drive chassis. I popped the old drives in and everything was still there working perfectly, without any reconfiguring. 6 Terabytes of data/photos/video clips safe and sound. Good product, great support. Thanks Drobo!
