Sorry to hear of your loss.
Once you get back on your feet, you need to look at this as a learning experience. If you have dedicated that much money, time and effort into your hobby, it is absolutely ESSENTIAL that you backup your data in several different locations. Hard rives are dirt cheap these days. I currently back up all of my music, digital pictures, important text and financial documents, and music projects to three different local computers, and I have a portable hard drive with those files that I keep at an offsite location. The simplest, cheapest and most effective backup software I found is called SyncBack. It's one of those programs you just set and forget, and then it works behind the scenes flawlessly.
So if you can make multiple local backups, AND make an offsite backup, then that would be the best solution, and it would require some strange act of God for you to lose all of your data completely.
And hopefully, other Head-Fiers will learn from your misfortune. You need to backup your data folks. If you don't it will only end in tears.
And with that said, I'm off to double check to make sure all of my backups are safe and secure...
EDIT: Read through and saw that the OP was able to recover. Happy to hear that, but let me tell you that he is one lucky S.O.B. Back up your data people. I can't stress this enough. People on Head-Fi spend thousands upon thousands of dollars on music gear, what is another $500 or so dollar investment to backup one of your most cherished possessions - your music collection?
