If bad sectors on a WD hard drive are detected, you can attempt to use low-level formatting to remove or repair the bad sectors. This will regenerate the disk layout and structure. However, it's not recommended as it leads to significant data loss, and it's not a procedure that ordinary users should attempt, as it can result in severe data loss.
The best solution to this problem is to replace the faulty WD drive with a good one, as recommended below. However, if you insist, back up your data to another drive first, then take the disk to a local repair shop or the manufacturer for a low-level format.
If the disk is severely damaged, bad sectors cannot be repaired. In this case, the sensible option is to replace the problematic WD hard drive with a new one.
To avoid data loss, we suggest you use a powerful hard drive cloning software - Disk Copy to help clone WD HDD to the new one for hard drive replacement.

Step 1: Download, install, and run the Disk Copy utility on your computer.
Click “Disk Mode,” then select the hard drive you want to copy or clone. Click “Next” to continue.
Step 2: Select the target disk.
Note: If you're copying or cloning a hard drive, the target disk should be the same size or larger than the source disk.
Step 3: Check and edit the disk layout.
If your target disk is an SSD, check the “Target is SSD” option.
If prompted, confirm that you want to erase the data on the target disk.
Step 5: Click “Continue” to start the hard drive cloning process.
Just wait for the process to finish. You can apply and activate this software to help you upgrade and clone a hard drive with bad sectors and recover data as much as possible.
When the cloning is complete, shut down your computer, install the upgraded drive into your computer in place of the original Western Digital drive, and configure your BIOS settings to boot from the new drive rather than the old one. You should then be able to see all your important data intact.
