I have an old hard drive that i used to run multibit classic bitcoin wallet on. I formatted the laptop back in 2014 and lost a wallet backup along the way. I tried recovery software to find the file but the wallet file i needed was classed as unrecoverable, i can see it but it looks corrupted. The .info file was intact but not the .wallet file.
I know we have a lot of knowledgeable people on here so I thought I would reach out for any advice on if any advanced data recovery methods could recover the file.
