All hard drives fail, because despite their connection to electronic devices, hard drives are (or were) mechanical in nature: a physical platter spins at thousands of revolutions per minute and a moving arm equipped with magnetic sensors reads magnetic pulses stored on the platter. The first hard drive hit the market in 1956 it was a 5-megabyte drive for an IBM mainframe, it weighed more than a ton, and it eventually failed.
