A hard drive read/write head uses magnetism, not a needle. It floats above the platter on a cushion of air generated by the rotation of the platter.Oh FYI?
You guys have something called "google".
You can actually look this stuff up all by yourselves.
Leave the dark caves..little ones.
The world is a very big and interesting place.
I dont see anything about a needle that scratches the surface of the hard drive. Is that in the next paragraph?
I corrected that so there would be no misunderstanding while you were posting. It just works on a somewhat similar principle that I thought some might understand to see how the data is not all affected and can even then be recovered fully most times.
