Like you said--based on my vague description, and vague memory--I do not know if I set to "cpu mine" or not. I suppose I need to just plug in the HDD and see if it is in working order (hopefully it is). A few hours of my time is worth it. Even if I don't find any bitcoin in the wallet, I'm sure there are some documents and things on there that would be worth a blast from the past. What's the worst that could happen? I don't find a treasure, that I already don't have?
I will probably start the process on Wednesday this week. With the holidays, have a lot of family stuff going on. I will keep you up to date.
Any suggestions?
If I find the wallet.dat file, how will I know if there is anything in it of value? Or will I need to import it to a new wallet to find out? I know that I will need to save the wallet.dat file multiple times before I do anything with it.
Thanks!
Holy crap. You may have won the lottery. I don't want to get your hopes up for nothing but I'll tell you what I know of Bitcoin, as you say an experienced user's perspective, and you may find it helpful.
Bitcoin has gone through various stages. It was introduced October 2008 and the network started up with the first blocks mined January 2009. At that early time there was pretty much nobody on the network besides Satoshi. As word spread a few others joined but there was still pretty much nobody even I'd estimate months later (say < 1,000-5,000 people). Now, surely there were
some people. That's why I don't think you're just making this up. People wouldn't have thought it a big deal at the time. My point is the coins mined then would have been many because difficulty would have been so low compared to today.
One thing I'm pretty certain of is
you were mining Bitcoins. At that early time the entire focus of the software would have been mining. People didn't even have anybody to send bitcoins to so the 'wallet' part of the software wasn't emphasized.
The only question then is whether you found anything or not. For that I'll relate a bit of my own history. I heard about Bitcoin some time in 2010 but dismissed it. By the time I dove in it was around December 2010 and I started running the mining software. I ran it for maybe 4 hours and didn't find anything, but this was an ordinary PC and I knew interest was already getting significant so I didn't really expect anything. I figured it would be easier to buy any coins I wanted. Your timeline would have been different, though. Way back in 2009 even mining for a few hours might have found at least one block which would be 50 coins (now worth over $500K) and maybe several. To put things in perspective realize finding blocks was so easy at one point people had several
thousand bitcoins. They had so many one guy famously bought a $14 pizza using 10,000 bitcoins.
So that means... there is a higher chance you found at least a few coins than there is that you found nothing, if you were on the network early enough, even if you only mined a few hours.
So next steps? Obviously guard that harddrive with your life lol
Seriously, guard that harddrive
As you say you're going to need to find out what's on it. But you have several things going for you. Even a damaged drive can have data recovered from it. In the worst case you might need to research into and undertake specialized data forensics of the kind the FBI uses, but that's in the unlikely event the drive can't be read normally. Even if files were deleted they may be recoverable. That's how persistent the data is. Just keep the thing away from any big magnets.
If you can access the drive then, yes, the first thing you'd do is back up important looking files several times. Of course the main file you're looking for is wallet.dat, but if that's not there it may not be the end of the story. As I said the software has underwent a lot of changes, including how data is stored. For as long as I can remember the file has been wallet.dat, but it may have been stored some other way early on. If you start poking around and find something interesting, but run into a wall and can't go any further I'd try to ask Gavin Andresen. He's still around in the Bitcoin community and fairly easy to contact (he hangs around reddit.com/r/btc and has a twitter for example). Gavin was one of the earliest programmers to work on Bitcoin besides Satoshi, so he'd know.
Best of luck, my friend! Of course it goes without saying, don't give anyone any exposure to any private keys you find as you seek any further help.
