I've had it, I've researched this inability to finish downloading the bitcoin core for a long time. I've rescanned, reindexed, removed and clean installed, mem checked, read lots of posts on similar issues. I'm ready to toss in the towel and just eat the ..05 bitcoin loss. It's in an Armory wallet btw and I'm using Bitcoin-Qt for the download. It's an i7 machine with 32Gb ram and an SSD not overclocked I guess it's my turn to post the last of the log file.  Please share your insight. Huh  Cry I'm going to bed. Undecided

Your copy of the blockchain contains a corrupted block. You will need to delete the corrupted block and reindex the blockchain which will take several hours. To do this first stop Bitcoin Core. Then go to blocks folder in the Bitcoin data directory (for you that is C:\Users\john-asus\AppData\Roaming\Bitcoin\blocks) and delete the files blk00589.dat and rev0589.dat and any blk*.dat and rev*.dat files that have higher numbers. Then start Bitcoin Core again. It will tell you that it needs to reindex the blockchain, click Yes and let it do that. Once it finishes, it should resume syncing the rest of the blockchain. Note that the reindex will appear as if it is syncing the blockchain; it is not.

Do you think it would be better to rename the bad block rather than delete it? I'm not sure how SSDs work, but in the past when using HDDs, I've found it better to rename the file to prevent a bad sector on the disk being reused,

Modern hard drives detect by themselves bad sectors and make sure they are no longer used.
In OP's case, it is bad blocks wrote on its hard disk, that would be caused by a crash or misuse. Deleting the block file could help the client to redownload, I guess.
IMO, I would delete everything and download the whole chain again.

.
SSD's have a micro controller which manages the access to the memory cells. Broken cells won't be used anymore for storage.
SSD's have more cells than actually 'needed' to achieve the promised capacity. Those start getting used when old cells die.
Renaming the block instead of deleting it would just use space (unnecessarily).


for reference: a small picture of a 'typical' SSD controller:

Why don't download the BTC blockchain, so that you have less time waiting for the client to sync and make sure everything will be synced correctly in lesser time rather than waiting for the client to sync for so long and then getting error message after 1 month waiting and trying, join this Bitcoin Blockchain Download [bootstrap.dat] thread and download the blockchain there

He have BTC blockchain's blocks that is bad it is a file that is corrupted during syncing, its not the block sector of the disk [SSD or HDD] that is becoming bad.

Locked up at 99% so I shut it down properly to work on it later. Next morning I clicked to wrong batch file and did a -reindex. Heart sank, I'm an idiot.  Day later it stops at 16% and there is a banned peer list I've never seen before. So WTF is that? Besides the obvious that is.

Here is the log when it happened. Which seems to go on forever so I'll not post the repetitive.

Have you try downloading the blockchain and bootstrap the client with it, if you worry about any malicious code or anything that comes with the blockchain download just use it as trial system to make sure your client is able to sync using your current network and computer system.

I guess downloading the bootstrap is what I'll have to donate to. My bitcoin-qt hasn't moved in 24 hours. No peers.  When this hobby worked it was enjoyable. I'm months into my btc wallet recovery and I just want to move my btc into something that works,, like eth which I'm mining now. I don't see much future for an unusable blockchain with high fees too boot.

I've got 99% of it. I had it synced a few months ago with the transaction (with fees) but it never finished. I'm open for suggestions.

The error with peer banning is happening because a block that it read is probably corrupted and that block is marked as invalid. Then Bitcoin Core will try to continue to sync from its peers, but those peers are sending it the block that it had marked invalid so it will ban those peers. Eventually it will ban everyone it could get a connection to. To fix the peers banning problem, stop Bitcoin Core, delete the file named peers.dat, and start Bitcoin Core again.

I suspect that you have a hard drive failure. You have experienced what appears to be two cases of corrupt blocks on your hard drive. I suggest that you run hardware diagnostics to see if it finds anything wrong with your hard drive. You should stop running Bitcoin Core for now as it won't be doing anything if it can't sync the blockchain.

Why don't just export the private key and use electrum to spend it, here is good guide to Transfer wallet from Armory to Bitcoin-Qt

If you still want to try syncing your client you can try download the blockchain using torrent here for free, I am not affiliated with any of this service and please do proper virus scanning of the file once you downloaded it from this sites

I think you should try doing scandisk on your drive, maybe its can help eliminate all the file corruption problem.

Thank you for the advice. I've done the peers delete and I've got peers again but they quickly vanish. Nothing much else is moving.

Ran the tests on my SSD (Samsung 950 pro 1Gb) and it's had no errors.

P2P the file maybe the answer

Did you delete the faulty blocks?

Here is my past cropping up again - have you checked the cable connections for the hard drive? Make sure there isn't any magnetic interference around as well. I'm clutching at straws, but you never know. Smiley

No peers, no traffic, no cpu usage, nothing, Been a few days now.

All the computer tests show good. SSD is and has been error free. ( It's solid, lol)

I'm at a loss. I'm tired of researching. I've tried everything I've read to save the blockchain I've downloaded at least twice. Amory is dead too (as in no traffic, no cpu usage, nothing). I've reloaded the system clean once and after ten days the second download also hung at 99%. I started this wallet recovery in December.

What are my options to easily convert my btc into eth?  Doing the p2p thing just isn't something I'm having faith in.

You may have another problem with your computer if you're getting corrupted blocks and get blocked by others. There is a reason to this.

If Bitcoin Core is able to read your wallet, you've access to your private key(s). Export these keys using Debug Console (dumpprivkey <your bitcoin address> - A private key in wallet format starts by 5 or L or K, depending the public key is compressed or not) and use Electrum as suggested to sweep coins from your old address by one managed by Electrum (Wallet/Private Key/Sweep). Electrum is able to run without download the whole chain, using API calls to remote nodes.

You can also use a online wallet allowing to import private keys.

I'm quite interested in this problem, and I would be grateful if someone could run through the sequence of events. I've never used an armory wallet.

I understand the sequence in a standard core download. You install the core software, and then either you give it an empty directory for the blockchain, or you give it a preloaded directory for it to check and synchronise. Once it has done that, does it create the wallet, or is that done in the initial core installation?

If you have downloaded 99% of the blockchain, would it not be possible to copy the created directory onto an external SSD ( or an SD card), and take it to another computer to install a new version of core, and give it the copied blockchain to see how it handles it?

If it has downloaded 99%, and then is failing each time, then the fault must lie in whatever operations core does when it completes the download. Were it to be a faulty block, then the additions to the blockchain between downloads would reduce the percentage.

At what stage do you give it an Armory wallet? Can you perform a standard installation, and add the armory wallet afterwards?

If the directory does not contain anything named wallet.dat, the client will automatically create the wallet file at start up.
If you have downloaded 99% of the blockchain, would it not be possible to copy the created directory onto an external SSD ( or an SD card), and take it to another computer to install a new version of core, and give it the copied blockchain to see how it handles it?

It's possible and thats essentially what the OP is doing now. If anything, I would suspect that the SSD has some issues with it and its not with the computer or the synchronization itself.
At what stage do you give it an Armory wallet? Can you perform a standard installation, and add the armory wallet afterwards?
Yes. Armory just needs the data from Bitcoin Core to run. As long as you can point armory to the synchronized blockchain, it would take a few minutes to read the blockchain and create its own database.
