About Clonezilla

Clonezilla is a free and open source hard drive cloning and imaging program. It is available in two editions Clonezilla live, which allows you to create a bootable CD/USB disk that you can boot the computers running various system (including Linux, Mac OS, Windows, FreeBSD, NetBSD, OpenBSD, and more), and Clonezilla Server, which allows you to clone many computers over network concurrently. many users have tried to use Clonezilla to clone hard drive. Some of them complete the process without a scratch while the others end up with an error. Clonezilla failed to clone for many reasons. Is there any way to fix it or troubleshoot?

The Cause and Solution

Bad sectors are often the cause to cloning failure. A bad sector is a tiny cluster of storage space that cannot be used to read or write data, so likely Clonezilla failed due to bad sectors. You can try the following command to check and fix bad sectors: sudo e2fsck -f /dev/sdxy (“x” represents the drive letter and “y” the partition number). Note that the partition to be checked has to remain unmounted. If you want to check Windows partitions (usually NTFS and FAT32 formatted), use the following: chkdsk /f. However, if the bad sectors cannot be fixed, you can enable the advanced extra parameters to skip bad sectors. Then you can transfer the data that can be read and accessed from one hard drive to another.

Advanced Param Extra

If you are trying to clone a large disk to a small disk, which means some block has to be dropped in the cloning process, Clonezilla wouldn’t know which blocks to drop. Therefore, clone hard drive failed with Clonezilla. To work this around, you can either shrink the source partition(s) or use a same size or larger size hard drive as destination disk. If you really want to clone larger disk to smaller disk via Clonezilla, you can check the option "-icds Skip checking destination disk size before creating partition table" in the advanced extra parameters.

If you still cannot manage Clonezilla to clone your hard drive, you can try another program that will automatically avoid such problems.

Smoother way to clone hard drive

AOMEI Backupper Standard is also a free hard drive cloning software for Windows 10/8.1/8/7. It completely supports cloning large disk to small disk as long as all the data on the source disk can fit the smaller one. By default, AOMEI Backupper will ignore bad sectors while cloning or backing up. What’s more, it allows you to clone MBR to GPT or clone GPT to MBR without reinstalling Windows. If you’re not using Windows operating system, you can also boot your computer with a bootable CD/USB disk created by AOMEI Backupper to clone hard disk.

To clone hard drive with AOMEI Backupper:

1. Download and Install this freeware, and open it to configure a cloning process.

2. Click “Disk Clone” under Clone tab. If you want to clone one partition or more, click “Partition Clone” instead.

Disk Clone

Note: This version only supports cloning disk with the same partition tyle, such as, cloning GPT disk to GPT disk. If you want to clone GPT disk to MBR or migrate MBR disk to GPT, you could consider upgrading to AOMEI Backupper Professional.

3. Select the source disk by clicking on the disk you want to clone, and click "Next" to continue. In the next screen, click on the destination disk receiving the data, and then click “Next”.

4. If it is an SSD you want to clone to, check the option “SSD Alignment”. Then click “Start Clone” to start the cloning process.

Start Clone

For the intuitive interface and good performance, it is recommended to try AOMEI Backupper if Clonezilla failed to clone. Beside, AOMEI Backupper is also regarded as an extraordinary free backup and restore software. You also can upgrade to AOMEI Backupper Professional to restore to dissimilar hardware.
