hdd issues after power outage

Hard drives are one of a computer’s most essential and fragile components, as they are responsible for storing data on the computer. A power outage is, unfortunately, one of the most common ways hard drives are damaged.

In this guide, we will discuss the symptoms of HDD issues after a power outage and the ways to deal with them. 

What are the symptoms of HDD issues after a power outage?

There are several signs to look for if your hard drive is not being detected after a power outage, and some of the most common ones are:

  • The computer will not start – If the hard drive in question is the primary storage for your computer and is damaged due to a power outage, then the computer will not boot up.
  • Disk boot failure – If upon starting the computer, you see a disk boot failure error message on your screen, your hard disk may be damaged. 
  • Data corrupted – If you can’t access your files and folders on your computer after a power outage, then it is possible that your hard drive is not working correctly. 
  • Slow performance – One of the reasons for the slow performance and frequent crashes is a damaged hard drive.
  • Clicking sound – If you hear a grinding or clicking noise when your computer starts, then it could be a sign of hard drive damage. 
  • S.M.A.R.T error – If the hard drive is damaged, you will get an error when running a diagnostic tool or CHSDSK command.

Before moving to other troubleshooting steps, please go through these preliminary checks:

  9. Check the hard drive settings and ensure the drive is the primary boot option.

4. Check it on another computer 

If nothing has worked for you, pull out the hard drive and try to use it on another computer. If the other computer detects the hard drive, the issue might be with the computer you are using. 

5. Replace the hard drive 

If the hard disk is not detected on another computer, you need to replace the hard drive as the hard drive is damaged. 

It would be best to use reliable third-party recovery software to recover data from the corrupted drive. Once recovered, you can transfer that data to the new drive. 

As hard disks are sensitive to damage by power outages, it is critical to understand the level of damage and fix the problem accordingly.
