Background of my problem

A few days ago my Dell XPS 720 decided to die on me. When I push the power button it turns on for about 1/2 second and then turns off. After much debate, I bought a new power supply for it (non-standard of course [24pin AND 20pin power connectors]). Today I received the power supply and low-and-behold that wasn't the problem. Now I need to buy either a motherboard or a new CPU (the existing one is a Core 2 Quad Extreme 3.0). I decided that buying from Dell was a bad choice and I'll just build myself a Phenom II system. Meanwhile, the XPS 720 shipped with 2x 120GB 10k Raptors in a RAID-0 using the sub-par onboard SATA RAID controller. I would just love to get my data off the system, but I can't get it up and running and I'm not going to sink anymore money into it. I decided to figure out exactly how the data was stored on the array members and try to deinterlace it directly into a raw image that I could then mount via loopback device in Linux and copy all my data back out 🙂 It sounds easy, huh? I found this GREAT little python code snippet that does the heavy lifting for me – thanks Sim
