SMART is a monitoring system built into modern hard-drives which monitors various factors that may affect drive reliability, such as read/write errors, bad sectors, high temperature, etc. When these factors exceed a certain value, SMART can predict that the drive is about to fail, and warns the user in time (to hopefully back up and replace). You can check SMART on Ubuntu with Disk Utility or with the smartmontools package.

How can I check the SMART status of a SSD or HDD on current versions of Ubuntu 14.04 through 20.04?
How can I check the SMART status of a drive under 14.04 and beyond? I've seen Checking HD SMART status on a fresh install but it doesn't seem to apply under 14.04 and later.
