HDI - Head to Disk Interference.
That's called a headcrash. Usually, the head and platters never touch, because the platters spin fast enough to generate an "air cushion" on which the head glides around.

A head crash is a type of hard disk failure that occurs when a read/write head touches the fast spinning disk platters. It is very catastrophic - it can destroy lots of data - even the data needed to start an operating system can be destroyed.
In a hard drive, the read/write heads float on a cushion of air above the platter. This ensures that there is a tiny gap between the heads and the spinning platter, allowing the heads to read and write data without physically touching the surface of the disk.

a. controller failure b. the read/ write head is in contact with the platter c. hard drive is in power save d. hard drive is in labor
