Thanks, I'll try that. Though I don't have the hash value. The header error references a file position.
"Errors in block header at FlatFilePos(nFile=2248, nPos=75228559)"
Are there any other errors beside that line? It indicates a corrupted file.
Usually, you just have to -reindex to fix it but you already on the process so there must be an issue somewhere else.
Maybe it's still not done with the reindex because of the hardware since you're using a NUC device and an external SSD.
You can try to speed it up by using more of your RAM by increasing the "
database cache" by a reasonable amount (
Settings->Options...->Size of database cache).
Set a value depending on your usual RAM usage (
e.g. Half), but do not set it too high.
While you're in the settings, see if you have "
pruning" setting enabled since you might not be needing it because you have enough space in your external SSD.
Plus reindex will trigger a full resync if your blockchain is pruned.
Incidentally why does it have two % complete values?
The % above is just for the "
block headers", the one below is for the entire blockchain (
the actual sync progress).
