Accessing HDD S.M.A.R.T info

  1. S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system for computer hard disk drives (HDDs) and solid-state drives (SSDs)[1] to detect and report on various indicators of reliability, in the hope of anticipating failures.

    (see the wiki for details)

    really cool info on the health of your HDD, BUT - - - just how the heck do you access that data?

    There are 3rd party tools you can buy, but I much prefer the free Defraggler software (aka a smart defrag) by Pirform Ltd.

    Use Runas Admin on a shortcut and then click on the Health Tab - - it's there in all its glory
    (some systems may need to Enable SMART in the BIOS to collect this information).

    Specific items that should concern you:
    • Read Error Rate
    • Reallocated Sector Count[*]
    • Seek Error Rate
    • Recalibration Retries
    • Uncorrectable Sector Count[*]
    • Multi-zone Error Rate
    [*] should remain constant and nonzero is common fresh out of the box :sigh:

    Suggestion: get a screenshot of your current values and compare to newer values over time to determine if the drive is showing signs of impending failure.

    Some Dell machines have SMART disabled in the BIOS by default. Maybe mention BIOS setting too.
