I know the feeling! My hard drive started clicking one day and then stopped working. Luckily I hadn't formatted my cards so I still had the past few months photos. I also just finished updating my backups to my ehds and backblaze. I only lost a few items that were on my hard drive but it was all reproducible.
After I got a new hard drive I spent a day organizing all my drives. I have my new ehd for photos, completed layouts and family info. Another older (2 years?) ehd that has all my design files and my ancient ehd that has my scrap stuff. Most of my scrap stuff is also on DVDs and everything is on backblaze. I think I have it covered.
