Have a look on the [wiki:FAQ FAQ Page] too, where you find information concerning more specific issues. == Manpages == If you are having trouble understanding the output of smartctl or smartd, please first read the manual pages installed on your system: {{{ man 8 smartctl man 8 smartd man 8 update-smart-drivedb man 5 smartd.conf }}} Here are on-line versions of the smartmontools man pages: [/browser/trunk/smartmontools/smartctl.8.in smartctl manual page][[BR]] [/browser/trunk/smartmontools/smartd.8.in smartd manual page][[BR]] [/browser/trunk/smartmontools/update-smart-drivedb.8.in update-smart-drivedb manual page][[BR]] [/browser/trunk/smartmontools/smartd.conf.5.in smartd.conf manual page] Note that these are the manual pages for the ''current version'' of smartmontools in the developers SVN repository; they might not correspond to the (possibly older) version of smartmontools installed on '''your''' system. So the manual pages installed on your system should be regarded as definitive for your installation. ---- == Tutorials == [wiki:BadBlockHowto Bad block HOWTO for smartmontools] [http://blog.shadypixel.com/monitoring-hard-drive-health-on-linux-with-smartmontools/ Monitoring Hard Drive Health on Linux with smartmontools ("Random Bits", Jan 2009)][[BR]]Step by step for beginners.

The RAW values of SMART attributes (temperature, power-on lifetime, and so on) are stored in vendor-specific structures. Sometime these are strange. Hitachi disks (at least some of them) store power-on lifetime in minutes, rather than hours. IBM disks (at least some of them) have three temperatures stored in the raw structure, not just one. And so on.[[BR]] Bruce Allen said on [https://sourceforge.net/p/smartmontools/mailman/message/10782139/ smartmontools-support list] (2007-08-31): ''The raw values for certain Attributes have vendor-specific meanings and are hard to interpret unless you know exactly how the vendor uses them on that specific disk model. The bit pattern might be a mix of flags, counters, and bitmasks, for example, leading to large and strange numbers. I wouldn't worry about the raw values very much. The normalized values (VALUE/WORST/THRESH) should have a sensible interpretation.'' Nevertheless smartmontools have a new EXPERIMENTAL feature to log ''Attributes Raw Data'' in external files. See option [https://www.smartmontools.org/browser/trunk/smartmontools/smartd.8.in#lbAE --attributelog] in smartd manpage and read the [wiki:attributelog authors instructions]. Franc Zabkar has a special interest in deciphering raw values. Read [wiki:raw_values some of his elaborated postings] on smartmontools-support mailing list. === External Information Resources === [wiki:Attributes_VendorDocs Links to vendor spec files for SMART attributes] Further collections see [wiki:Links] page. == Warnings == [wiki:Warnings] ---- '''License'''[[BR]] All content in this wiki is published under [https://www.gnu.org/licenses/gpl-2.0.html#SEC1 GNU GPL].
