Wallet.dat corrupted 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 &quot;wallet.dat corrupted, salvage failed&quot; 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?
I ran the blockchain during 2009 and 2010

By &quot;ran the blockchain&quot; 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 &quot;.dat&quot; 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
