On a Windows forum, a question goes, "Clonezilla failed to clone bad sectors on a laptop. Will chkdsk repair?" Most of the answers are suggesting the questioner replace a new hard drive. What if you're in the same situation but still have a try on your old hard drive? This article from EaseUS will focus on the same topic, telling you how to continue to clone a hard drive with bad sectors.

Why Does Hard Drive Get Bad Sectors

A hard disk is composed of several small storage space clusters. One cluster equals one or more sectors, and the number of clusters depends on the hard drive's file system. So, the cluster is the smallest allocation unit, and the sector is the smallest addressable unit. When bad sectors are on the hard drive, these sectors won't respond to read or write requests.

Generally, there are two kinds of bad sectors: one is the physical bad sector (hard bad sector), and the other is the logical bad sector (soft bad sector). The head of the hard disk drive is damaged, the dust has fallen on that sector, the flash memory unit of the solid-state drive is worn out, or other defects or wear problems may cause hard bad sectors to appear.

The soft bad sector appears because the operating system may have tried to read data on the hard drive from this sector and found that the error-correcting code (ECC) didn't match the contents of the sector.

Unfortunately, if your hard drive has bad sectors, this damage is irreparable. You'd better buy a new hard drive. However, if the bad sectors are soft ones, your hard drive can be repaired by overwriting the drive with zeros or performing a format.

Method 2. Check Bad Sectors on the Source Drive

If you get the "Clonezilla cannot clone bad sectors" error when using Clonezilla to clone a hard drive, you can try to repair or remove the bad sectors using the Windows CHKDSK tool and clone the hard disk. Here is a guide to running the CHKDSK command.

Step 1. Type cmd in the Windows search box and click "Run as Administer" to open Command Prompt.

Step 2. Type "chkdsk g: /f /r /x" and press "Enter". (Take "g" as an example; you need to replace "g" with the target disk.)

type chkdsk g: /f /r /x

Note: "/f" refers to repairing errors on the disk; "/r" refers to locating bad sectors and restoring readable information; "/x" refers to deleting the target volume.

Step 3. Input "exit" and hit "Enter" to exit CMD.

After removing the bad sectors on the drive, you can restart Clonezilla to clone the hard drive.

Final Thoughts

That's all about what you should do when you meet the Clonezilla failed to clone bad sectors error. In conclusion, whether a hard disk with bad sectors can be cloned depends on the type of bad sectors. If they are hard bad sectors, don't waste your time and buy a new hard disk. If they are soft bad sectors, you still have a chance to clone the hard drive with EaseUS Disk Copy. But you need to remember that this is not a 100% successful method. It still depends on the degree of sector damage.
