Just had this thought, and realized all my backups had been through a flood. I wound up with several damaged disks, but was able to get all the content off of them, damage was to the outside edges, and most of them didn’t have much data written.
I have a Blu-ray burner, but I’ve never burned one (only a couple DVD’s). Probably never will.
I feel like the second one gets me. The best sleep I get is in a terrifyingly cold room, snug and cozy under a heavy, warm stack of blankets.
