There is a leased dedicated server with one SSD for 512GB running Ubuntu 16.04. I have been renting for about six months. The load on the disk is constant. Not a moment's peace. Hoster when installing said that most likely the disk is new.
How, without deleting data and stopping running processes, check the disk for bad sectors?
How do you see from the results of the check that the disc is desirable to change?
