LevelDB read failure: Corruption: block checksum mismatch

[1337leet]

Hey guys,

I just started my bitcoin-qt wallet and started to sync. After a few minuted I got a fatal error.

Debug log says: "2016-12-01 18:45:31 LevelDB read failure: Corruption: block checksum mismatch"


I know it might be a problem with my storage (the wallet is on an external hdd).  The external hdd works just fine for everything except the bitcoin wallet. I get this error every few month.


Is there any possibility to fix this error without reloading the whole blocklchain?

To answer your question: Yes, you just have to reverify the database and not redownload it. If this happens regularly its a hint at hardware problems.

Hey Leute,

ich habe gerade meine Wallet gestartet und wollte syncen. War 3 Tage hinten dran und nach kurzer Zeit habe ich die Fehlermeldung "Fehler beim Lesen der Datenbank, Ausführung wird beendet" bekommen.
Neustart bringt nichts.

Kann mir jemand helfen?

Bitcoin-qt - Version ist ca. 6 Monate alt.

Ich möchte um jeden Preis verhindern die komplette Blockchain erneut zu laden.. das würde ca. 3 Tage dauern und ich brauche die Wallet morgen abend.

Do an update before you start with -reindex there was a recent patch that improved the performance.

Backup your wallet.dat (just in case) and reinstall the latest version. It will replace all needed files and keep the blockchain and wallet.

I updated to 0.13.1 and now started it with -reload. Afterwards I try -reindex.
Let's see if this will work.
