This article applies to:

Symptoms

  1. Using Acronis True Image you are trying to mount an image of a disk or partition of over 2 Terabytes in size;
  2. Acronis True Image fails to mount the image with an error message similar to the following one:

Cannot assign a drive letter

Alternatively, the mounting can be successful, but the mounted disk is of unexpectedly small size and cannot be accessed.

Cause

When mounting, Acronis True Image emulates the image as a partition of an MBR disk (even if the image is of a dynamic disk). MBR disks do not support partitions larger than 2 terabytes.

Solution

You can restore separate files or folders from the image if this is what you would like to mount the image for.

More information

This is a known issue. It will be fixed in future. Unfortunately, there is no specific date for the fix.
