I'm curious about your "hobby". Do you only those HDD only to look abandoned wallet? Don't you use it for other hobby/task such as running BitTorrent/IPFS software or extra backup of certain data?
Nor really sure what you talking about
Is it something that i can search for Bitcoins? Cuz now what i do is simply run disk Drill and see if i find "peers.dat", "Wallet.dat", "BTC", "Seed" and other Bitcoin related keywords.
