- Using Acronis True Image you are trying to mount an image of a disk or partition of over 2 Terabytes in size;
- 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.
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.
You can restore separate files or folders from the image if this is what you would like to mount the image for.
This is a known issue. It will be fixed in future. Unfortunately, there is no specific date for the fix.
