I heard again about bitcoin in 2017 and immediately remembered my hard drive, which my grandfather had hammered into the wall of his garage as a tool holder.
Unfortunately for you and many other people who at first could not even imagine what value they actually have on their hard drives, fate has given you a really strong slap and left for sure a great feeling of regret for a lifetime. It's a real shame the hard drive from your closet ended up in the garage, but it is also a question of whether you would be able to save the data at all after so many years.
There is another very famous case of a person whose hard drive ended up in a dump and it contained thousands of BTC, or a case of a person who hid his private keys in fishing rods that ended up in a dump again. At least you know where your BTCs are, on the garage wall as tool holder which is currently valid between $300 000 and $400 000
