bitcoin core uses leveldb, there is some bug where it occasionally gets corrupted. it's pretty horrible. usually you don't need to redownload, just reindex.

I’ve had to do 5-10 reindexes on my node 😕 my drive is fine. I have heard many cases of this from other people.
I’m not worried about the drive. Time to do all this means I can’t accept lightning payments. No zaps, boosts or streaming sats until Core is resynced. Not gonna kill me but most of the support I get from the podcast comes it during this time.
