Thank you for the replies.  I am running a PC with 8gb ram and and an i7 processor and 400 Mbps internet connection.  I have an attached Samsung T7 2tb external drive to run a full node, not pruned.  It just seemed like it was indexing faster and faster than all of a sudden barely moving.  If it's still downloading the blockchain regardless of speed, does that mean there was no corruption in the blockchain that is downloaded so far?

When you say start resyncing, you mean delete everything and start over?

I'm trying to download a bitcoin node. Bitcoin Core Ver 26.0  Indexing started out fast but has now slowed to a crawl.  Bitcoin core did close down twice on its own (once because the hard drive went to sleep before I changed the setting and not sure why the second time).  Did that possibly corrupt the indexing? It started up fine when restarted but now is barely moving.   I closed the program with control q and let it gracefully shut down and rebooted the computer, but that didn't help. I'm down to 361,355 blocks left to index, but it says 10 days until completion. It's been running 30 hours.  I was at 47 hours last night and decreasing quickly.  Thanks in advance.
