Back on topic...
I let it sit in a very warm room for the weekend. It seems to be - MOSTLY - OK. At one point, it recognized the subdirectory structure, but no files in any of the folders. But that seems to have passed.
So I was able to back up the backups.
The next question is... Should I trust it to continue to be OK? Or should I just go out and buy a new one right now?
Thanks.
