Bad sectors are the damaged parts of the hard disk and can occur due to power surges, hardware failures, software issues, or even human error. These sectors prevent you from accessing your data, resulting in a computer crash.
A bad sector repair tool can fix the bad sector issue, but that doesn't mean the data on the bad sector can be recovered. There is a difference. So, apart from recommending bad sector repair software, this article will also tell you how to recover data from the bad sector.
To learn more about the bad sectors, read our guide "Bad Sectors on Disk: Everything You Need to Know.
While there is no way to repair a physical bad sector, you can sometimes fix a logical one in four different ways, including using high-end devices, searching for solutions online, using the Windows 10/11 built-in CHKDSK Utility, or using the WMIC tool.
Part 1. Backup Your Data Before Repairing The Bad Sector
If you have a bad sector on your hard drive, you may be able to repair it using a software tool. But before doing that, it's important that you back up your data because there is a risk that the data on the bad sector could be lost during the repair process, and you would not be able to recover it again.
So, if you have important data on your hard drive, make sure you back it up using the Recoverit Software before you attempt to repair a bad sector. This will ensure that you have a copy of your files in case something worst happens during the process.
You might be thinking, why Recoverit? Well, it is a robust, reliable, and easy-to-use software that can help you back up the data and recover it from the bad sectors effortlessly. Just install and launch the software, hit the Start button to scan the drive, and select Recover to save the recovered file to any external source.

Part 3. How to Recover Data From Bad Sector?
As mentioned above, even though the bad sector issue is fixed, you cannot recover the data on the previous crashed sector. To do this, you might want to take the help of software like Wondershare Recoverit or EaseUS to restore your hard drive data.
Below we've provided a quick overview of some of the features of Recoverit software for data recovery to see which of them sets it apart from EaseUS.
- 35 Patents: Recoverit has more than 35 patents for data recovery. Some of them are storage medium, device, Computer Equipment, and disk data reading method. The patent understands that when reading disks, the sector with the failed disk can be bypassed. The software improves data recovery and solves the problem of the read disk being stuck.
- Extraordinary scanning ability: With its excellent scanning capabilities, Recoverit can detect damaged files and displays only the good file for recovery. EaseUS, on the other hand, cannot tell the difference between the good and damage file and shows the three different versions of the same file.
- User Experience: Wondershare Recoverit and EaseUs Data Recovery Wizard have both been hailed as front-running data recovery software on the G2 platform, affirming their status as experts in the data recovery sphere. On TrustPilot, both of these software stand firm with a score of 4.0 or more in the reviews.
However, Recoverit stands out because its reviews are only for this product, while EaseUS reviews are for all products, not just its Data Recovery software.
With Recoverit, you can recover data from bad sectors in the following way:
Step 1: Go to the official Recoverit, and download the software. Now, install the software on your PC and launch it.
Step 2: On the software's main interface, select the hard drive with bad sectors and click "Start" to begin the scanning process on the drive.
Step 3: Once the scan is finished, preview the recovered files and select the data you need. Finally, click "Recover" to save the files on your PC. If you cannot find your lost files, rescan the drive with the All-Round Recovery mode for a deep scan of the hard drive's bad sectors.
In this article, we've briefly explained the 4 ways to check the hard disk for bad sectors without using the software. Afterward, we compared the ten best bad sector repair tools based on their price, compatibility, interface, hard drive support, success rate, G2/Trustpilot rating, and pros and cons.
