I ran Bitcoin during 2009 and 2010.

I found an old file I had renamed to xxxx.dat. I recently downloaded the Bitcoin.org wallet and let it run.

I get the "wallet.dat corrupted, salvage failed" message after I put in the file I believe to be my old wallet.dat. I have deleted the installation and restarted my computer. I hope to be able to start over. Any suggestions?

  • Can you be more precise about what it is you are trying to do? Do you have bitcoins you want to recover? Jul 6, 2020 at 5:07
  • I'm trying to see how many bitcoins are in it, and to recover them to cash in.

I ran the blockchain during 2009 and 2010

By "ran the blockchain" I guess you mean you ran Bitcoin-core wallet software sometimes known as Bitcoin-qt.

I downloaded the Bitcoin.org wallet

Bitcoin.org lists many wallets, I guess you mean Bitcoin-core wallet.

I found an old file I had renamed to xxxx.dat.

There are many different data formats and software applications that use ".dat" as a filename extension. So your xxxx.dat might not be a wallet.

Any suggestions?

Check the format of your xxxx.dat file. See if it matches the expected format.

There are tools that might assist with this - such as pywallet.

Otherwise maybe you have to download an ancient version of Bitcoin-core

  • It is from 2011. I thought it was a wallet from bitcoin core I purchased in 2011 to 2012.

  • Down load an ancient? I thought it would handle any bitcoin core wallet. Back then it was the only wallet. I've forgotten who or where I purchased them.

  • Bitcoin wallets are free, you would not have needed to purchase a wallet in 2011 or 2012. Jul 9, 2020 at 9:34
