So, I was having some fun repairing the boot sector of my computer so it would load Windows properly, and in the process I created a Windows recovery media on my flashdrive. It mostly had junk files so I didn't bother backing up anything. Then I realized it had my book on it...of course, this was after I had already cleared the drive to reformat. I did have a backup, but I've lost about four chapters and a lot of changes I made to the beginning...so, roughly thirty or so hours of work down the drain. I'm not happy, and this is a bit of a setback, but oh well. I only have my own idiocy to blame. Damn.
