Bitcoin Core keeps crashing while opening

[longbob72]

If I go to another disk and copy paste wallet.dat will it work ?

No because wallet.dat only have your wallet info and not the blocks. This is seems to be an issue with verifying blocks. Something which to my understanding usually caused by corrupted files or bad sectors in harddisk.

And I forgot that you can try downloading the whole blockchain again before trying to reformat.

 This will work but it would take days to get the entire block chain and you would have to rescan which would also take quite some time.
Are you saying it crashed again when you ran Bitcoin-qt with the -reindex command?  Is it running or not?

 I had to reindex on my laptop computer in the fall of last year and it took a good portion of a day.  My laptop contained an I7-720M with an SSD - the speed of your computer and virtual memory is critical in determining how long it will take.

It's been reindexing since 8:37p yesterday.

It's 7:57am

It has reindexed until 2 years and 48 weeks.

And I don't have all the blocks on my computer since I hadn't opened bitcoin wallet since about 1-2 years.

That's good news.  Hopefully this fixes your crashing issue.
Let us know!

Ok lol now it's 2 years and 25 weeks, I will let you know in 2 weeks

It's been what, 20 hours? You're still reindexing after all that time? That's not normal. If it goes on for 20 hours more it'll be faster to delete the block files and resync (if you don't mind the redownloading.).

about 20 hours yes I have a 4 year old mac

No it been 12 hours !

Ok I checked it is not reindexing, it is downloading the blocks now

Ah. That's good. I think reindexing fixed your problem. Post here if it still crashes after all that.

Yes ! When everything is ok I let you know, but it may take 1 month lol !

Isn't it a way to download the blocks from somewhere else than the wallet which is slow ?

Only other way is using bootstrap.dat. But they're downloaded using torrent and the download speed depends on the number of seed/peers. And you'll have to download the entire bootstrap which almost as huge as the current block size. The latest one is here (posted by wayneyoyo).

Edit:
Oh wait. That's not bootstrap.dat but the archived block files. Not much difference, though. The bootstrap.dat download link is posted on the first post of that thread.

 How about an update?  Is the program still running? Can you see any progress?
