Hello community ,

From past 1 month , my laptop's HDD in which windows is installed has a bad sector or a bad block , i even did a clean install of win10 , it did not go , so i guess this a hardware related issue , if so do i need to buy a new HDD or a SSD ? . The drive also has become kind of slow , pls tell me how to resolve this problem . TIA.

Regards ,

Manas

    Hi Manas,

    I am Dave, I will help you with this, you should not need to purchase a new drive, Windows should be able to repair the drive or bypass that block or sector.

    Is WIndows10 currently installed on that drive or do you want to clan install Windows 10 on that drive?

    If Windows 10 is currently installed on the drive:

    Click the power icon on your Start Menu

    Press the Shift Key and click Restart

    Your PC will boot into the Windows Recovery Environment

    Go to Troubleshoot - Advanced Options - Command Prompt

    Run this command and press Enter

    chkdsk C: /f /r

    Wait for that command to complete, was that command able to fix your drive?

    Hi Manas

    When Windows finds bad blocks on your drive, they are marked as bad, they do not get repaired, but they are skipped by the operating system when saving data to the drive, so if you have bad blocks, you would expect to see them in the event viewer, this is not an indication of any further damage to the drive and should not be causing any problems with Windows 10.

    Hi Manas

    What was the output form that command, did it indicate bad sectors or blocks that could not be repaired?

    If it did, then re-installing Windows 10 will not solve this problem, because it is hardware, not software.
