I have some experimental drivers on my laptop and they occasionally blue-screen it. Thus far I tried 7-unzip twice and in both cases it worked and saved lot of re-indexing time. I just delete what's left in the chainstate directory right after blue-screen.
Interestingly Litecoin doesn't suffer the chainstate corruption under exactly same circumstances.
Great ! this is what i was looking for. Let's hope I don't run into the problem of having to reindex. I need to make sure I close down bitcoin core well and completely is something I've read regarding this problem elsewhere in these forums.
PS: Didn't know litecoin was still kicking; I bought a very little amount many months ago and saw that the price had collpased so thought it would probably dissapear completely.
