I know the feeling. I lost my hard drive a couple of years ago. It took me a long time to get over the disaster, but it did teach me a good lesson. A backup drive is the only way to go.
I guess I did my thing differently. I just started over and eventually built it back up. I'm back up to about 2.6 g with my McLaren folder. Not ever sure what I'll do with all of that. I now have (2) 500g drives and use one as a backup. Not sure what the answer is as far as selling photos. I know it's still max-
frustration for you. Hang in there, it'll just take time of get everything back.
