Scenario: Acronis clone disk failed, see log for details


Hey. I bought a couple of Crucial BX300 (120gb) SSD's to upgrade a couple of computers at home to make it run faster for my Windows 10 laptop. But I get the following error when I use Acronis to clone the hard drive:

"Disk cloning has failed. See log for details."

I found the tool which lets me view the log files. I made two attempts to clone and both log files say the same thing. Please see the attachment. The hard drive in the laptop is 1tb but has less than 100gb used space. Can anyone tell me why can’t I clone with Acronis?

Many thanks,

- Question from Acronis Forum


Acronis True Image is widely regarded as top-notch cloning software today, preferred by many for disk cloning tasks. While it's generally efficient with minimal failures, there are times when it might falter, leading to error messages. Some common errors include:

Common errors of Acronis clone disk failed:
Clone Disk Operation Failed
Failed to run the task
Error 0x13c0005: Operation has completed with errors
Failed to execute the task script. 0x10002 Error #1364
A specified authentication package is unknown 0xFFF0
Error 0x00640067+0x0009FFFF
Clone failed to read sector/data from the disk

Why do the Acronis failed to clone disk?

These error messages often mean that your disk is corrupted, damaged, or other problems, which will easily cause issues like Acronis clone failed to read sector/data from the disk. Another common problem is when cloning hard drives from computer brands like Dell or HP. They often have locked partitions, especially the recovery partition, which can cause failures during the cloning process. At this time, people should usually create these recovery partitions to solve problems such as the operating system being damaged and unable to boot or the screen turning blue or black.

The third issue is that when you move from a large hard drive to a smaller solid-state drive (SSD), Acronis may not resize the recovery partition, finally leading to clone disk failed. However, you can still clone between drives of different sizes as long as if you choose a qualified tool.

To fix that, the Acronis official also provides suggestions like:

1. Check that other operations that require a system reboot (e.g. system disk recovery) are running.
2. Upgrade to the latest version to see if that solves the problem.
3. If your computer has enabled EFI mode, please boot the bootable media in EFI mode and then collect a system report.
