Bad News

While I was installing some new system software, my back-up drive was nuked. I only  noticed a week later that my photo library was gone. After using some data recovery software I managed to get half my library back but all of the adjustments I have ever done we gone. This is a setback, but I can only hope that out of this will come good things. Word of advice, If you use time machine on an external drive make sure there is nothing important on it...
