With respect to hard drives, the acronym “SMART” stands for Self-Monitoring, Analysis and Reporting Technology. This was built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. Basically anything after about 2005 should have it.<\/p>\n

smartctl<\/p>\n
The program smartctl is used to interface with the SMART features on the drive firmware. Here are a couple of easy things to get started with (however some versions do not have the –scan option):<\/p>\n
\n\n$ smartctl --scan -d ata\n\/dev\/hda -d ata # \/dev\/hda, ATA device\n\/dev\/hdc -d ata # \/dev\/hdc, ATA device\n$ sudo smartctl --info \/dev\/hdc\nsmartctl 5.42 2011-10-20 r3458 [i686-linux-2.6.33.1-xedvia] (local\nbuild)\nCopyright (C) 2002-11 by Bruce Allen,\nhttp:\/\/smartmontools.sourceforge.net\n\n=== START OF INFORMATION SECTION ===\nModel Family: Seagate Barracuda 7200.7 and 7200.7 Plus\nDevice Model: ST3160023A\nSerial Number: 5JS9MDKW\nFirmware Version: 8.01\nUser Capacity: 160,041,885,696 bytes [160 GB]\nSector Size: 512 bytes logical\/physical\nDevice is: In smartctl database [for details use: -P show]\nATA Version is: 6\nATA Standard is: ATA\/ATAPI-6 T13 1410D revision 2\nLocal Time is: Thu Feb 7 09:27:18 2013 PST\nSMART support is: Available - device has SMART capability.\nSMART support is: Disabled\n\n<\/pre>\nNote that the “SMART support” is listed as available but disabled. To enable full diagnostic checking turn it on with something like this:<\/p>\n
\n\n$ sudo smartctl --smart=on --offlineauto=on --saveauto=on \/dev\/hdc\n=== START OF ENABLE\/DISABLE COMMANDS SECTION ===\nSMART Enabled.\nSMART Attribute Autosave Enabled.\nSMART Automatic Offline Testing Enabled every four hours.\n\n<\/pre>\nIn theory this should only need to be done once and the drive should remember this (because of the saveauto directive). The offlineauto will cause automatic testing every 4 hours. In theory it will wait “nicely” if the drive is already busy so performance should not be seriously impacted.
\nTesting<\/p>\nHere\u2019s a way to run a “short” off-line test. This tests electrical and mechanical performance of the drive and does read testing.<\/p>\n
\n\n$ sudo smartctl --test=short \/dev\/hda\n=== START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===\nSending command: "Execute SMART Short self-test routine immediately in off-line mode".\nDrive command "Execute SMART Short self-test routine immediately in off-line mode" successful.\nTesting has begun.\nPlease wait 1 minutes for test to complete.\nTest will complete after Thu Feb 7 10:13:19 2013\nUse smartctl -X to abort test.\n\n$ sudo smartctl --log=selftest \/dev\/hda\n=== START OF READ SMART DATA SECTION ===\nSMART Self-test log structure revision number 1\nNum Test_Description Status Remaining LifeTime(hours) LBA_of_first_error\n# 1 Short offline Completed without error 00% 43398 -\n\n$ sudo smartctl --log=selftest \/dev\/hdc\n=== START OF READ SMART DATA SECTION ===\nSMART Self-test log structure revision number 1\nNum Test_Description Status Remaining LifeTime(hours) LBA_of_first_error\n# 1 Short offline Completed: read failure 90% 37994 7234643\n\n<\/pre>\nThe first command starts the test off and it tells you to come back in 1 or 2 minutes. The second command shows how to query the log file to see if anything bad came up. In this case hda was fine (“Completed without error”) but hdc had a very important “read error”. Replace that drive ASAP!<\/p>\n","protected":false},"excerpt":{"rendered":"
