Acronis Clone Disk Operation Failed Error

You may have seen some Acronis Ture Image cloning problems in forums, and we list the two of these problems as below:

"I have a 250GB HDD in my laptop, and I was planning to replace it with the new 500GB SSD drive. So I used Acronis True Image to clone my 250GB HDD to SSD drive, but I got the “Clone Disk Operation Failed” error message. I tried it twice and the error still appears. Any idea what I could do?"

"I have added a second WD 160GB hard drive to my Dell desktop, there are some data that I want to clone with Acronis True Image, when the cloning process completed around 20% and the program give me this error: failed to run the task. I have CHKDSK my WD 160GB drive and found no errors. However, I still cannot accomplish this cloning operation. Any help would be appreciated."

Except for these two errors, you can also see other error messages like the following:

  • Failed to execute the task script. 0x10002 Error #1364;

  • A specified authentication package is unknown 0xFFF0;

  • Error 0x00640067+0x0009FFFF.

The Cause

The Acronis clone disk operation failed problem is caused by the issue in the Acronis True Image. You can upgrade to the latest build to see if the problem is solved. If the Acronis error clone disk operation failed cannot be fixed, what would you do? Perhaps, a similar hard drive cloning software will be your best choice.

1. Select Clone at the left hand, then choose Disk Clone.

Disk Clone

◑ If you just want to migrate your system to the target SSD, choose System Clone (available in the offcial version). It will automatically select the operating system drive and boot-related drives, so you don't need to worry about missing some important system files.
◑ Except for cloning MBR system disk, you can also clone GPT to GPT, MBR to GPT, GPT to MBR with the Professional version. 

❕ Both MBR and GPT are two different disk types for data storage. If you are not clear about this, please check its partition style with the following steps. 

  • Press Win + R to open the Run window. Then, type diskmgmt.msc and hit OK to open disk management.
  • Then, right-click the disk you want to clone and select Properties in the pop-up window.
  • In the Properties window, select the Volume tab and confirm the partition style. It can be MBR (Master Boot Record) or GPT (GUID Partition Table).

Disk Partition Style

2. Choose the hard drive (HDD) you want to clone.

Source Disk

3. Select the specified SSD drive as your destination disk.

Destination Disk

4. Tick SSD Alignment option to speed up the performance of the SSD, and prolong the lifespan. And then, press Start Clone to Clone HDD to SSD to avoid Acronis clone disk operation failed error in Windows 11/10/8/7.

Start Clone

★ Tips
You can also tick the Sector by sector clone option if your SSD drive is larger than HDD, and it will clone all sectors on the destination and cost much more time. 
Edit Partitions allows you adjust the partition size and location while cloning disk to larger disk to fully use the storage on larger destination disk.

BTW you cannot use them together. If the NEW SSD is larger or it has different disk type (MBR or GPT), I'll use the premium feature - Edit Partitions without a doubt. 

  • Copy without resizing partitions: It will not resize the partition size.
  • Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
  • Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. 
  • Convert the destination disk from MBR to GPT: It helps to convert the partition style of the destination disk if it is different from the source disk.
