 smartctl 5.43 2012-06-30 r3573 [x86_64-linux-3.3.8-gentoo] (local build)
 Copyright (C) 2002-12 by Bruce Allen, http://smartmontools.sourceforge.net

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 ===

[http://builds.smartmontools.org/ 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
