Windows 10: How do I fix bad sectors on my hard drive??

Lenovo scanned my system and it said that my hard drive failed the Targeted Read test, tried fixing it but it couldn't and it's 8 bad sectors. I've ran sfcscannow, chkdsk, DISM and nothing seems to be able to fix this. Do I need a new hard drive? this one is only about three years old.

HDD Bad Sector

Hi Nataniel!

I am not sure what your question is exactly, but one thing I'd recommend for sure will be to look for a replacement drive since there is already a bad sector on your current one.

Basically there are two kinds of bad sectors - hardware and software:

• Hardware ones are caused by physical damage or becoming magnetically fixed, and they are unrepairable. In short, once they appear it's only a matter of time (no way to say how long) until the HDD fails.
• Software bad sectors on the other hand occur when something called an Error Correction Code (ECC) doesn't match the contents of the hard drive. These can be repaired by overwriting the data on the drive with zeroes (a.k.a. low level formatting) and sometimes
  by running a **chkdsk [write the letter of the drive:] /r** in the CMD.

As for getting the information from the drive if one of the partitions fail, most likely you won't be able to, which is why I'd suggest to make a regular backup of your most important data.

Hope this helps and feel free to ask any questions you may have.

 

hard disk bad sector repair in Windows 10

Hi Mohqasim,

Before proceeding further, please answer few queries.

1. What is the make, and model of the Computer?

2. What is the complete error message/code you receive?

As per the description, I understand that there could be some bad sector in the hard disk.

Meanwhile, I would suggest you to follow the below steps to run the check disk, and check.

1. Press Windows + X, select Command prompt(Admin).

2. Type the following command, and hit Enter.

chkdsk /r/f

Disclaimer: While performing check disk on the hard drive if any bad sectors are found on the hard drive, then chkdsk tries to repair that sector if any data available on that might be lost.

Please let us know if the issue got fixed or you need any further assistance.

Thank you.

Hi,

Thank you for providing us with the response to our questions.

I suggest you to run Check disk and check if it helps. Remove your external Hard drive and perform the steps on your system:

Check disk is a utility that can check your hard drive for corrupted segments and fix them. You can refer to these steps to run the Check disk utility:

• 
  Press Windows key + X, select “Command promt (Admin)”.
  
• 
  In the command prompt window, type
  “chkdsk/r” and press Enter.
  
• 
  Press “Y” when it asks if you want to check disk to run when the computer boots the next time.
  
• 
  Restart the computer for Check disk to detect and repair any corrupted sectors in your hard drive.
  

Important: While performing Error-checking or ChkDsk on the hard drive, if any bad sectors are found and when attempting to repair that sector, the
data available on that sector might be lost.

Please let us know if you face any issues with Windows.

Thank you.
