Well, I've come to grips with what has happened. The only major issue is that painting I had been working on for weeks is gone. My music is on my iPod, so I can get that easily enough. I have most of the apps I was using, so I can just install those from disc. It still makes me sad, but it's probably for the best. I learned a valuable lesson tonight, and I'll be up until 2 thinking about what I've done. From here on, I keep a recent back-up image on CD...Just in case.
