I started the initial sync with prune. When i went to bed last night it was at 55% and when i woke up it got to 75%. Now while sitting here i noticed Bitcoin Core suddenly was gone without warning. I started it back up and now it’s at 55% again. The night before that i left it running and it did the first 40% without issue.

Now i only have 90gb left on my disk and i’m afraid that’s not going to be enough. The blocks it discarded are apparently still on disk. Also, the "prune" checkbox in the settings is now suddenly unchecked. It also wasn’t complaining about my "banscore" configuration before.

Does anyone have a clue what happened here? Was this a disk failure of some sort? How can i get rid of the blocks it’s not using anymore? Can i just check the prune checkbox again and it’ll be fine?

It says the following in the debug file:
