Just think of the insane amount of labor that would be required to manually sift through every inch of ten plus years of accumulated garbage searching for a tiny little object.
Not just from one person's garbage but from tens of thousands or hundreds of thousands of people's garbage.
Who does he think is going to perform all that nasty work for him? Who on earth would be willing to do that nasty job?
How many months or years would it take? Is he going to do it by himself?
Come to think that even just leaving that hard drive on a dump site for 3 days or even a week would already that impossible for such recovery of those coins. This is why it would really be that somewhat useless.
It would really be best that you should really accept your fate on which there's no way that you could be able to see those coins again. There are really things in life on which if it isnt ours then it wont be.
Missed out opportunities could really happen into our lives and there's nothing we can do but to move on. Yes, its painful and a true nightmare. If you have decided to spend up some money to
get that harddrive back then its your choice but you are just basically wasting up your time and money.
How many years had passed already? Corrosion or water damage for sure it is.
