Why is the hard drive clicking?

Question

Iron

It clicks at the moment of rebooting the computer - once, and neither earlier nor later. Pretty loud. Clicks for almost a year)
what is it? Is it curable?

Answer 1

It is treated by going to the store and replacing it.
in more detail, when you turn it off clicks? What if you unplug it?

Answer 2

Most likely the head parking is so loud. Do you have to turn off the disk after idle time? If you turn it on and let it stand, it may also click.

Answer 3

The main thing is that it doesn’t click during operation, but don’t touch it like that, although I wouldn’t store important data on it

Answer 4

is not treated. Head parking.
