Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.)

SmartMonTools is used to access the a hard drives S.M.A.R.T. information.

The examples below use /dev/sdX as the first internal hard disk drive, and /dev/sdY as the external USB drive.

All the commands listed are good for both Linux and Windows unless otherwise stated.

HOWTO: INSTALL

Windows

Download and install the .exe file.

Linux

sudo aptitude install smartmontools

HOWTO:

Scan For Devices

sudo smartctl --scan

Scan For Devices And Try To Open Each Device

sudo smartctl --scan-open

Device Driver

sudo smartctl --device=test /dev/sdX

/dev/sdX: Device of type 'scsi' [SCSI] detected
/dev/sdX [SAT]: Device open changed type from 'scsi' to 'sat'
/dev/sdX [SAT]: Device of type 'sat' [ATA] opened

So, we use the sat driver for this device.

Enable SMART Feature

sudo smartctl --device=sat --smart=on /dev/sdX

Information

sudo smartctl --device=sat --all /dev/sdX

Health Check

sudo smartctl --device=sat --health /dev/sdX

Tests - Internal Drives

Self-Test: Short (internal SATA)

sudo smartctl --device=sat --test=short /dev/sdX

Self-Test: Medium (internal SATA)

sudo smartctl --device=sat --test=conveyance /dev/sdX

Self-Test: Long (internal SATA)

sudo smartctl --device=sat --test=long /dev/sdX

Tests - USB External Drives

Self-Test: Short

sudo smartctl --device=sat,16 --test=short /dev/sdY

Self-Test: Medium

sudo smartctl --device=sat,16 --test=conveyance /dev/sdY

Self-Test: Long

sudo smartctl --device=sat,16 --test=long /dev/sdY

The last long test on an external USB drive may need to be combined with this series of commands to stop the kernel from sleeping the drive:-

while true; do dd if=/dev/sdX iflag=direct count=1 of=/dev/null; sleep 60s; done

Stop Running Tests

sudo smartctl --device=sat --abort /dev/sdX

Display Test Logs

sudo smartctl --device=sat --log=selftest /dev/sdX

The output should look like the following:

    sleep 60s; 
done
