Failed to Read/Write Sector Reasons

1. 1. Hardware issues: There may be physical damage or defects in the source or destination drive, causing read/write errors.
2. 2. Loose or faulty cables: Poor connections or faulty cables can cause intermittent read/write errors. Reconnect or replace the cable.
3. 3. Software problem: The EaseUS Disk Copy software may be damaged or not functioning properly. Reinstall to ensure you have the latest version.
4. 4. Drive incompatibility: Outdated firmware or drivers on the drive or system may cause compatibility issues.
5. 5. Disk Errors: Bad sectors on the source or destination drive may cause read/write errors. Use Windows File Explorer tool or third-party tools such as CrystalDiskInfo to check and repair bad sectors.
6. 6. Low System Resources: Low memory, high CPU usage, or other resource-intensive processes running in the background may interfere with the cloning process. Close unnecessary apps and processes. Make sure that your system has sufficient resources to handle the cloning process.

Check the Hard Drive Health

Use hard disk detection tools such as CrystalDiskInfo to check the health status of the hard disk and see if there are bad sectors or other hardware problems.

• Look for "Reallocated Sectors Count".

• "Uncorrectable Sector Count" indicates permanent failure.

If the hard drive is old or badly damaged, it is recommended to back up important data as soon as possible and then replace the hard drive.

If it's primarily a bad sector problem, continue reading. Next, we will discuss in detail how to fix the problem of read and write failure caused by bad sectors.

What Is a Hard Drive Sector?

A sector (typically 512 bytes or 4K) is the smallest storage unit on a disk. A bad sector is a tiny storage unit on your hard drive that becomes unreadable or damaged. It can be caused by software errors (fixable) or physical damage (permanent). When encountered, your computer may freeze, crash, or show errors like "Read/Write Sector Error." When the cloning tool attempts to read or write these bad sectors, it will report an error because the data cannot be accessed correctly.

Bad sectors of hard disk are divided into physical bad sectors and logical bad sectors.

• Physical bad sectors are caused by physical damage to the hard disk surface and cannot be repaired, and the data cannot be read.
• Logical bad sectors are caused by file system errors, disk management errors, etc., and can be repaired by software.

Fix Logical Bad Sectors

In the Windows system, you can run the "chkdsk" command through the Command Prompt to check and repair logical bad sectors. Here are the steps:

Step 1. Type Command Prompt in Windows search bar and choose Run as administrator.

Step 2. Type chkdsk X: /f /r and press the Enter key. X is the disk letter that you want to check.

• /f fixes file system errors.

• /r locates bad sectors and recovers readable data.

Step 3. If the error persists, back up data first, then format the drive.

Handle Physical Bad Sectors

Since physical damage is irreversible, it's important to create a complete backup of the hard drive to maintain the integrity of the data. You can use the disk cloning software like EaseUS Disk Copy to clone the hard drive with bad sectors or select skip the bad sectors.

Use a new hard drive to ensure that the cloning process is completed smoothly. In this way, you have the chance to ignore bad sectors during copying without data loss.

After cloning, you can do the following:

• Verify the cloned drive: boot from it or check file integrity.
• Retire the failed drive: continued use may worsen corruption.

Tips to Avoid Sector Errors

• For HDDs: Avoid shock/vibration during operation and monitor temperature, if >60°C it will accelerate wear.
• For SSDs: Enable TRIM, fsutil behavior setting Disable Delete Notify 0. Avoid exceeding 80% capacity to avoid affecting read/write speeds.
• Regular data backup: Perform regular data backup to prevent sudden data loss.
• Regular SMART checks: Use CrystalDiskInfo for early disk problem troubleshooting.

Conclusion

A "Read/Write Sector Error" during cloning in EaseUS Disk Copy can be solved easily with the methods in this post. From hardware issues to using the chkdsk command to detect and repair bad sectors, and to cloning the disk to prevent more bad sectors from spreading, all of these are effective solutions to sector read failures.
