Questions tagged [smart]
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.
