A month ago my dad was fixing his computer and he was about to throw away his hard drive and I asked him for it and he gave it to me. I opened it up with a screw driver and studied it with a magnifying glass. This is what it looks like.
I think the orange computer chip is transferring the data to the brown strip. Then, the brown strip transfers the data to the little needle. I think the needle has a chip in it so it can transfer the data to the disc and both disc’s store the data.
The way people get their data back from their computer is, they unscrew the disc from the hard drive and put it in a new hard drive.
I think that is how a hard drive works. I am going to do research on it so that I can find out how a hard drive actually works.
