Hard drives are slowly being replaced by SSDs, but the transition will take a few years before SSDs become mainstream and hard drives disappear completely.

One reason users prefer SSDs instead of hard drives in addition to price is that SSDs are much faster than mechanical hard drives.

Bad sectors on hard drives

Bad sectors are a common problem when using hard drives. A bad sector is actually bad disk space. You cannot read or write data to it. A bad sector may already have data, but it cannot be read or restored.

Bad sectors, although common on hard drives, can also occur on SSDs. Sometimes they can be fixed, but sometimes nothing can be done.

Finding bad sectors on a disk

Before you can fix bad sectors, you need to know where they are and how big the problem is. You can search for bad sectors with a simple check.

There are two easy ways to check for bad sectors on a disk.

File management

  • OpenFile management (Windows + E.).
  • Click in the left panel This PC.
  • Right-click the partition / drive and select Features in the shortcut menu.
  • Go to the tab Tools and click Ensure.
  • Allow the scan to complete.
  • Repeat for all readers.

Command prompt

chkdsk /F /R
  • Let the command complete. It returns a list of bad sectors on the disk.

Fix bad sectors on disk in Windows 10

Windows 10 cannot fix bad sectors. Once you have found the bad sectors on your hard drive, check how much drive has been lost due to the bad sectors. Depending on the damage, try one of the solutions listed below.

Replace the hard disk or SSD

If you have a lot of bad sectors on your disk, you can’t do much to fix them. Back up any available data, and then consider replacing the drive.

You can clone an old damaged drive to a new drive, but we do not recommend it for a drive with bad sectors. Manually copy the information and reinstall Windows 10 if necessary.

Correct disk errors

  • If there are only a few small and scattered bad sectors on the disk, the data can be recovered from them or even corrected.
  • Open a command prompt with administrator privileges.
  • Run the following command:
chkdsk C: /f
  • Repeat this command for all drives in the system. In order, VS: indicates the letter of the drive.

Data recovery tools

If you have too many bad sectors, your data may be lost. If you have not backed it up, you can try to restore it using data recovery tools. Remember to manage your expectations because a bad sector is not always the best way to recover data.

Conclusion

Hard drives have become faster and more reliable. Even faster storage is available in the form of SSDs, but they still have their limitations. Sometimes drives can have bad sectors right out of the box. If the drive is new, you can probably replace it under warranty. Physical damage can also lead to bad sectors; so pay attention to how you handle your material.
