Question: my external hdd stopped working and makes weird noises. opened inside of it then uploaded a video. please help me, i am about to lose 10 years old <> archive

Answer:It’s not “capitalism” or “planned obsolescence”.
It is simply an electromechanical device. Such devices can and do fail. We as humans do not yet know how to build something like this that will not break.

Before you opened the case, there was a slim possibility of recovering your data. This may have involved money to a company that specializes in this, but that possibility existed.
After you opened it, I’m pretty sure no company will touch it.

Hard drives run with incredibly tight tolerances. The gap between the spinning platter and the heads is on the order of 3 nanometers.
Opening that drive case needed to be done in a clean room. Which you do not have. The dust/pollen/skin cell filled air in your house has deposited all sorts of stuff on that drive.
Stuff too small to see with the naked eye. But to a flying read head, that like running into a boulder with your car.

10 years of data on a single drive? Why have you never thought of, i dunno….having a second copy for safekeeping?
