Using S.M.A.R.T to check disk health

https://linuxconfig.org/how-to-check-an-hard-drive-health-from-the-command-line-using-smartctl 

 smartctl has to be run as sudo or root user 

 

 

 

 smartctl -a /dev/sda  shows all smart data from a drive 

 

 

 

 

 

 

 

 Run the following tests in the scenarios 

   

 

 short test

 

 The  short test is meant to quickly check the most common problems that could be found on a storage device. The test should take no more than 10 minutes: mechanical, electrical and read performances of a disk are checked. 

 

 

 long test

 

 The  long test is basically a more accurate version of the “short” test. In can take a lot of time to complete: as stated in the the smartctl manual, it can last from tens of minutes to several hours. 

 

 

 conveyance test

 

 The  conveyance test is meant to check for possible damages occurred during the transportation of the device. It usually takes minutes to complete a conveyance test. It is available only on ATA devices. 

 

 

 select test

 

 The  select test, like the “conveyance” one, is available only on ATA devices, and is meant to check only the specified range of LBAs (Logical Block Addresses). The range of addresses is specified when launching the test. For example, to check addresses from 10 to 20 (inclusive), we would run: 

 smartctl  -t select,10-20 

 

 

 

 

 

 

 

 

 

 

 

 -t option is for running a test immediately and specifies the test type 

 short for --test
