I seem to have even lost my cookie. :-/
I'm going to have to do what we did with my son's computer a couple of years ago. Put in a new hard drive, larger, and place the original drive in a box or slave position. I'll explore to find the gazillion photos that I don't seem to have backed up. I was sure I had backed it all up this summer, but I'm not finding the files I thought I had. My monitors are screwed up, the fonts look odd, I'm out of sorts. Best to stop while I'm ahead!
Research time: I'll either get locally or order the new drive, and I will also get a second external drive, much larger for a full system backup and I'll do incremental backups from now on. Memory is cheap, a day like this is a bitch!
