Trying to Recover an Old Wallet.dat File

Hey everyone, A while back, between 2011-2012, I was mining using Bitcoin-QT. Back then, I had no clue what I was doing and ended up deleting it from my old computer to free up space. Super regrettable, right? I’m not tech-savvy at all, and I’ve been trying to get this wallet back for years. I did manage to back up the disk, but I don’t remember much after I deleted Bitcoin-QT. The computer didn’t see much use after that since it eventually broke down, but I still have the hard drive and a copy of it.

With how a Bitcoin private key works, it's pretty wild. Like, nearly 2^256 means finding one randomly is almost impossible. If you think you found one, maybe you somehow imported it from another wallet. If you're hoping for more bitcoins, they might be from different keys, but they could be corrupted or have flipped bits. You might need to tweak them a bit to get anything back.

Thanks for your reply! While scanning hex values, I found multiple identical codes. For instance, 15 times the same value D030123456…47 00. I converted just one to WIF. Is this normal? So I need to convert the hex to WIF and then mess around with the prvKey values, right? Could entering the wrong password while using Pywallet cause results like this?

Those might not be actual private keys. The chance of random collisions is super low. Most likely, you’re looking at duplicates of your wallet.dat or the same private key being imported multiple times. Just tweak the private key by flipping one or more bits at a time. You might need to visualize it in binary format, which is not an easy task.

Hey folks, Quick update on my progress. I’ve spent weeks trying to recover my old encrypted wallet.dat from a full dd disk image. I think the original wallet.dat got fragmented over time. The filename and path are gone, so normal recovery tools like Recuva and Photorec haven’t worked at all. I’ve been working on Python scripts to scan the disk image.

I shared something a while ago. Check out my last post. You can test your info offline with it. You can even tweak it to suit your needs. It’s a long road ahead, but good luck with it!

Something about your story seems off. In early 2011, mining with just a CPU was tough. Difficulty and hashrate levels were already high. I know there could be details you didn’t mention, but I really doubt you mined anything just using a CPU. By then, GPU mining was becoming a thing, and FPGA miners came out later that year, which blew GPUs out of the water. I was mining with a modest GPU back then and had to join a pool just to get a little something.
