Now coming to checking internal hard drive then it is not, that easy. However if your system is showing internal hard drives then it simply means that there is nothing wrong with the power.

There are possibilities that your PC is not able to read the hard drive so in this case you need to try it with other PC. If it is working then you need to check other components of your PC which is raising problem.

You can simply reinstall hard drive drivers by going to This PC (right-click) > Manage > Device Manager. Right click on hard drive and click on Uninstall. Now restart the computer, it will fix the problem most of the time.

You can give one more try by changing the drive letter that are assigned to storage media to repair corrupted hard drive.

Check If There Are Any Errors

Windows has inbuilt feature that will help you to check errors for internal or external HDD, storage media etc. In many case Windows will ask you for scanning the drive when you connect any external drive to the system. If it is not asking then follow:

This PC > Drive (right-click) > Properties > Tools tab. Click Check.

The hard drives that we have on our laptops and systems integrated with hardware monitoring technology called S.M.A.R.T. The sad thing is Windows doesn’t have any app which can show you S.M.A.R.T. data  but still you can check overall status using Windows Management Instrumentation Command Line or WMIC. Give it a try.

  • Click on Start button and type CMD in it.
  • When list is open right click on CMD and select run as administrator
  • Type wmic and press enter
  • Type diskdrive get status and press enter

It will start showing you S.M.A.R.T. data. If it says OK then your hard drive is fine but if it is showing the status of not then you need to consider it seriously as it might get completely corrupted in near future.

Things become more complicated when you are using multiple hard drives. We are saying this because it doesn’t show the name.

If you are facing the same issue then simply use CrystalDiskInfo software which will show you all details about your hard drive like overall health, the number of start counts, temperature, total number of active hours and more.
