This article from EaseUS will tell you how to use the SSD bad sector repair tool to fix bad sectors on SSD. Hurry up and learn!

SSD Bad Sector: Overview, Symptoms & Causes

Let's learn some basic information on bad sectors to choose a better solution and remove them from your SSD drives.

Overview of Bad Sector on SSD

Bad sectors, also known as bad blocks, refer to specific areas within the computer's hard disk or flash memory that have become unreliable for saving and reading data, which can no longer be written to or read from accurately, leading to potential data corruption, data loss, and decreased PC performance. Like the bad sector on HDD, the bad sector on SSD can be classified into 2 types: logical bad sectors and physical bad sectors.

Logical bad sectors result from logical errors, usually caused by software problems or file system errors. The good news is that you can repair the logical bad sectors, making data accessible again. Physical bad sectors result from actual damage to the flash memory cells. These sectors are technically irreparable, and stored data may be permanently lost.

Symptoms of SSD with Bad Sector

While most SSD drives report lower health only related to the wear-out caused by writes, we can still find bad sectors on SSDs in many situations. The symptoms are usually:

• The file(s) or folder(s) stored on the SSD may be unreadable, corrupted, or damaged.
• The SSD may be much slower than ever before. The read speed is usually very low for some data (if the file can be read).
• The Windows system frequently crashes, may be slower than before, or may be unable to boot as the SSD may not be recognized by the system.
• Bad sectors reported in the text: There are 16 bad sectors on the disk surface, or the drive found bad sectors during its self-test.
• Sudden file disappearances that occur without user action can result from bad sectors, causing the file system to lose track of data.
• The Windows may also prompt you to run a disk check (CHKDSK) to signal potential SSD issues.

Causes of Bad Sectors on SSD

Many factors can cause bad sectors on SSD, and the following are common causes. Let's take a glance at what they are:

• Tear and wear. The NAND flash memory cells within SSD can wear out over time due to continuous read and write actions.
• Physical damages. Exposure to extreme temperatures or moisture, a drop, or a shock can damage SSD NAND memory cells.
• Software and firmware issues. Sometimes, errors or bugs in the software or firmware can cause logical bad sectors.
• Manufacturing defects. Certain SSDs might have manufacturing defects in various forms that affect their quality and reliability, although this is rare.
• Power issuers. Sudden power surges or faulty power supplies can impose damage on the SSD electronics.

Other causes, such as improper shutdowns, malware infections, etc., can result in logically bad sectors.

How to Fix Bad Sectors on SSD on Windows 11/10/8/7

Technically, you can't fix bad sectors. Indeed, you cannot repair physical bad sectors on SSD, but this is not the case with logical bad sectors. As you know, when Windows detects bad sectors, it marks them as unusable, whether logically or physically bad sectors. As a result, data loss is inevitable. Read on to learn how to repair bad sectors on SSD drives.

Urgency: Clone SSD to Another One for Data Security

If the SSD really contains tons of bad sectors and is frequently stuck or very slow to read and write data, or if the SSD is failing due to physical bad sectors, it is totally out of the question to repair bad sectors on the SSD.

The wisest and best choice is to back up and save data on SSD to another one or an external drive. But how to transfer data from one SSD to another or how to copy an SSD with bad sectors to another?

You can use professional disk cloning software like EaseUS Disk Copy to help you, as Windows does not have cloning software. If your SSD is not completely going bad, you can use EaseUS SSD cloning software to clone a hard drive with bad sectors. Some of the highlights of EaseUS disk cloning software include:

EaseUS Disk Copy can help clone an SSD with bad sectors to a healthy drive without trouble. Just download it on your PC to save your data stored on SSD! Here is how to use it:

Step 1. Download, install and run EaseUS Disk Copy on your PC.

Click "Disk Mode" and select the hard drive that you want to copy or clone. Also tick the "Sector by sector copy" option if your hard disk has bad sectors. Click "Next" to continue.

Step 2. Select the destination disk.

Note: The destination disk should be at least the same big or even larger than the source disk if you want to copy or clone the source hard disk.

Step 3. Check and edit the disk layout.

If your destination disk is an SSD drive, do remember to Check the option if the target is SSD.

Step 4. Click "OK" to confirm if the program asks to erase data on the destination disk.

Step 5. Click "Proceed" to start the hard drive cloning process.

Repair Logical Bad Sectors on SSD in Window

If the bad sectors on SSD are logical, you can use the Windows built-in tool (Scandisk) to fix them. The following is how to use Scandisk on Windows 10:

Step 1. Press Windows + E to open File Explorer.

Step 2. Click on This PC in the left pane in the File Explorer window.

Step 3. The right side of the window displays a list of hard drives. Right-click on the SSD you want to run Scandisk on and select Properties.

Step 4. Click Tools in the Properties window.

Step 5. Click Check under the Error checking section.

Step 6. Click Repair drive and wait for Windows to automatically repair it.

How to Check Whether SSD Has Bad Blocks

Since bad sectors can cause data loss, it is important to confirm their presence on an SSD. The Windows built-in tools can check bad sectors on the SSD drive. It is vital to note that if the SSD contains essential files, the first move is to back up data instead of repairing bad sectors. As mentioned above, you can clone the SSD with bad sectors. Here is how to check whether SSD comes with bad sectors:

Way 1. Use Scandisk

Scandisk can not only help you repair bad sectors but also check bad sectors on SSD. You can follow the steps above to check the bad sector on your SSD drive, so I will not give unnecessary details here.

Way 2. Run CHKDSK

You can also use the Windows tool - CHKDSK to perform a preliminary check of bad sectors on SSD. Here is how to go for it:

Step 1. Click Windows+R to open Run dialogue, type cmd, and press Enter.

Step 2. Input command: chkdsk C: /f /r /x and press Enter.

• "C" is the drive letter of the disk you want to check
• “/f” tells CHKDSK to fix errors it finds
• “/r” tells locating bad sectors and recovering readable information
• “/x” tells unmounting the disk to be checked before scanning

FAQs on How to Repair SSD Bad Sector

1. Can SSD bad sectors be repaired?

It depends. If it is logical bad sector, Scandisk can fix it. However, if it is physical bad sector, it cannot be fixed. The good news is no matter whether it is a logical or physical bad sector, you can clone the SSD to a new and healthy one to avoid data loss.

2. What do Ido if my drive reports bad sectors?

If your hard drive reports bad sectors, you can use the Scandisk tool to help you repair bad sectors on it, but the physically bad sectors cannot be fixed. Therefore, you can directly clone the hard drive with bad sectors to a new one. Professional disk cloning software like EaseUS Disk Copy and Clonezilla can help you.

3. If a hard drive develops a bad sector, should it be replaced?

It depends. The logical bad sector can be repaired, but this is not the same case with the physical bad sector. In this case, replacing the old disk with a new one is better. You can transfer your data between the hard drives via cloning.
