Acronis True Image Hangs When Cloning

Acronis True Image Cloning - Stuck on Less than 1 Minute

“I've been running the cloning all day, as it errored last night and I had to wipe the SSD clean and start over. I'm on Windows 10 x64, cloning a 1TB SATA to a 1TB SSD to speed up my laptop. I booted my laptop, opened True Image, selected Clone from the tools and selected "Automatic". I've been stuck on "less than 1 minute" for nearly seven hours now. What is going on???”

As a powerful disk imaging software, you can use Acronis True Image to clone to SSD and other drives. It also has backup, archive, access and recovery features.

However, sometimes users may also encounter problems when using this software. The above two cases are the problems encountered by users that Acronis True Image hangs when cloning. How to solve it? Find the solution below!

How to Fix Acronis True Image Cloning Problems

Acronis True Image Hangs When Cloning

As in the cases above, users often meet that Acronis clone stuck processing. Such as stuck on “Calculating time remaining”, “Less than 1 minute”, etc. This situation often happens when you plan to clone a hard drive on your laptop. Cloning a hard drive in the laptop to an externally connected drive may cause the system to not work properly, so it is not recommended. It is recommended to put the new drive in the laptop first, and connect the old drive via USB.

There is another situation that can cause the Acronis True Image cloning process to stop at 80%-95%. The real reason is Acronis cannot clone some hidden partitions under normal conditions. To avoid this problem, you can create a bootable rescue media. It will boot the system outside of Windows and allow Acronis to clone the hidden partitions. Steps to create a bootable rescue media via Acronis True Image 2020 are as follows:

Step 1. In the Tools section, click Rescue Media Builder.

Rescue Media Builder

Step 2. Choose media creation method. Here I click Simple as an example. Click here if you choose Advanced.

Choose Creation Method

Simple—This is the easiest option, suitable for most users. Acronis True Image will choose the optimal media type for your computer. If you use Windows 7 or a later version, WinRE-based media will be created. Otherwise, Acronis Media Builder will create a Linux-based media.
Advanced—This option allows you to choose a media type, therefore you can create the rescue media not only for your computer, but for a computer running a different Windows version.

Step 3. Select a destination for the media. You can select CD/DVD, USB flash drive, ISO image file, WIM image file.

Choose Media Destination

Step 4. Finally, click Proceed.

Acronis True Image Restart Is Required

Computer Restart Is Required

This situation often happens when users want to clone to WD SSD. WD SSD does not come along with disk cloning software, so many users turn to Acronis True Image WD edition to replace hard drive. When you encounter this problem, you can turn off the Secure Boot option to solve “Acronis computer restart is required”.

Step 1. When your computer starts up, you can press Delete key to enter into BIOS in common situation. (Some computers may require pressing F2 or F12, you can check the computer's motherboard specification or computer’s user manual for detail.)

Step 2. After that, you can find “Secure Boot” option in BIOS (usually under “Security” or “Boot TAB” option).

Step 3. After turning off “Secure Boot”, press F10 to save the setting and exit BIOS.

The above two problems are only a small part of the Acronis True Image cloning problems, there are many other problems, such as Acronis not recognizing WD HD/SSD, Acronis True Image WD edition installation restricted. If you don't want to be bothered by these problems anymore, I recommend you to use the free software below.

Solve Acronis Cloning Problems - Once and for All

AOMEI Backupper Standard is a free disk cloning software. It’s the best alternative to Acronis True Image. It not only supports disk clone but also partition clone. This software can be your first choice for cloning hard drives for the following reasons.

◑ Intelligent Clone: It allows you to clone only used sectors from one hard drive to another while skipping bad sectors, thus you can easily clone a disk to smaller SSD or clone a disk with bad sectors without any obstacle. However, Acronis True Image hangs when cloning a disk with bad sectors. 
 Sector by Sector Clone: It allows you to clone all the sectors on a hard drive, even if the sector is blank or it is a logically bad sector. 
◑ SSD Alignment: This feature makes full use of 4k technology that can help you improve the performance of SSD disk.
