How to check S.M.A.R.T status of your harddisk for disk health

S.M.A.R.T.  ( Self-Monitoring, Analysis and Reporting Technology ; often written as  SMART ) is a monitoring system for  computer   hard disk drives  to detect and report on various indicators of reliability, in the hope of anticipating failures.  On Mac OS X : The following command will report the SMART status on Mac OS X  $ diskutil info disk0 | grep SMART The output will look like some thing below : SMART Status:             Verified  If the output says "F ailing " or " About to Fail ", other than "Verified" then you might need to backup data and try repairing the disk or replacing the disk. On Linux : $  smartctl -d ata -H /dev/sdb   This command will  run overall-health self-assessment test on your hard disk and prints a report of disk test results.
