Topic: 0.13.1 sync problems, nearly finished, but stopped up several times (Read 5113 times)

Yes, true, to copy it took only 55 minutts . And the hole shit startet with install of 0.13.1.

How long did it take you to resync under these conditions? Its 9 days since your first post. Just an idea. Im not doing it myself, but I also never had these problems.

Takes some time to copy the folder, 97 GB

Yes, that way you dont have to resync if the database gets corrupted again. You can just restore from the (uncorrupted) copy and sync the rest of the way (e.g. the month).

Yes, my wallet.dat backup was 1 year old. But you mean I should creat a backup copy of the hole folder?

Consider creating a backup copy of the folder once a month so you dont have to resync from scratch every time something like this happens (might very well been norton).

At last.
After bitcoin-qt stoppet 2 last time, I did'nt start over again.
I restartet my computer I opened Bitcoin Core again (it was 4 weeks back) and it sync to finished.
When starting up with this attemps I closed my Norton Firewall and used instad Windows Defender.
Not sure this was the reason for success. I opened Norton and could find that Bitcoin-Qt.exe was
on exeption. In Windows Defender it was possible also to set the map with BitCoinCore data on exeption,
but I cannot find something similar in Norton Firewall.

Thank you all for trying help me.

4 weeks left. an then, again:

Well, kinda. AFAIK bitcoin core can still be used for mining, even though it only makes sense on Testnets.

Checked the memory and it was ok. Maybe Win10, yes. When I used my wallet very often my operativsystem was Win7.

Just going off the specs here... might as well be Win10 mucking about with the files for some reason.
12 GB is kinda odd, are you using old RAM maybe? Like 4+4 new and 2+2 old or something like that.

It is a Seagate Expansion Drive SSD 2 TB. External. Program is on my c drive. I was first using my internal 1 TB hardisk.

Using Windows Defender with exeption. Else it's Norton.

Since this keeps happening, it might still be a hardware problem (e.g. disk [you switch it IIRC], RAM or CPU) or a problem with some software that is interfering with the data (e.g. anti virus or similar).

Error opening block database. Want to restore block database now?

The hole log is to big to post here.

Looks like you have nodes misbehaving, but that should be no issue.

This is from old topic when I had problem with my e: harddisk

No, it was not so easy. 39 weeks left it stopped up, but looks still working:

When scanning my harddisk it was repaired for a bad sector or something. I started to resync again, but it stopped up when I was 39 weeks left. Bitcoin Core asked me to start again and I answered yes, so it's on processing blocks again.

It is a Seagate Expansion Drive SSD 2 TB. External. Program is on my c drive. I was first using my internal 1 TB hardisk.

Well, you haven't really provided us with adequate information to come up with concrete ways to help you in addition to this being quite a specific problem. Your Bitcoin folder is not on an external disk, right?

Correct. Do not send the wallet.dat unless you plan on never using those addresses again.
