The -c/ -capabilities flag prints which tests a device supports and the approximate execution time of each test. Conveyance: identifies if damage incurred during transportation of the device.Extended or Long: the test is the same as the short check but with no time limit and with complete disk surface examination,.Short: runs tests that have a high probability of detecting device problems,.There are three types of self-tests that a device can execute (all are safe to user data): For example, specifying -device=ata tells smartctl that the device type is ATA, and this prevents smartctl from issuing SCSI commands to that device. ![]() If SMART is available but not enabled, you can enable it: # smartctl -info /dev/sda | grep 'SMART support is:' SMART support is: Available - device has SMART capability. The -i/ -info option prints a variety of information about a device, including whether SMART is available and enabled: Smartctl is a command-line tool that "controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS hard drives and solid-state drives." That done, you can manually #Run a test and #View test results, or you can use #smartd to automatically run tests and email notifications. You can use #smartctl to check for and enable SMART support. SMART support must be available and enabled on each storage device to effectively use these tools. ![]() Install the smartmontools package to use these tools. The smartmontools package contains two utility programs for analyzing and monitoring storage devices: smartctl and smartd. ![]() Statistics are collected (temperature, number of reallocated sectors, seek errors.) which software can use to measure the health of a device, predict possible device failure, and provide notifications on unsafe values. (Self-Monitoring, Analysis, and Reporting Technology) is a supplementary component built into many modern storage devices through which devices monitor, store, and analyze the health of their operation.
