Is it normal that the SMART extended self test to run for hours on a new hard disk. So far, the test is running on my laptop for 2 hours. What is it doing? If I stop the test, will it damage the hard disk? How long will it usually run?

For your references - Hard disk - Hitachi 7200 RPM, 1 TB. Software - Dell SupportAssist Test - SMART Extended Self Test Drive Status - Nothing installed, except Windows 7, drivers and Dell SupportAssist.

  • The fact it is taking so long indicates a hardware problem, will it damage the HDD? Well the HDD is already failing, but no, it won't

1TB SMART might run 2-4 hours

If dell provides the smartctl.exe command, you can check the progress via smartctl.exe -Hc c:\ it shows progress of the test (sometimes it hangs) and also the firmware reported test time. Look for Self-test execution status and Extended/Short self-test routine recommended polling time

install the windows version if unable to locate smartctl.exe -- http://sourceforge.net/projects/smartmontools/files/

full smart info: smartctl -x c:\

    I can see the progress. imgur.com/aeyPzA4 But the problem is, it is been the same. Shall I copy files while the test is running? Is it safe?

    yes, smart tests run in the background with low priority, so user actions are served first.
