Had a hardware failure a year ago, the technician saved my files and copied everything on a new hard drive. Including the ravencoin wallet. A week ago I decided to run the Ravencoin wallet but it was closing immediately. Tried to run the wallet.dat on a another pc and it showed the following message "wallet.dat corrupt salvage failed" Please give me some ideas on how to recover the data from inside the wallet.dat Private keys method extraction where a bit complicated for me via python salvage option. Please help, I have invested in it since 2018.
