If the issue persists, please collect some information to let us investigate it thoroughly:

- Reinstall Acronis drivers with enabled logging;

Please create Acronis Report and Windows System Information as it is described in Acronis Help Post.

Please make a screen shot of the Device Tree application the way described in this previous post.

Please also collect the application log of the operation:
- run the program;
- select Show log on the toolbar or from the Tools menu;

Then submit a request for technical support. Attach all the collected files and information to your request along with the step-by-step description of the actions taken before the problem appears and the link to this thread. We will investigate the problem and try to provide you with a solution.
