Introduction

When you transfer a system to a hard drive that is larger or smaller than the original one, Acronis True Image allows you to create a new partition layout to fit the hard disk of a larger or smaller size.

It is possible to restore a disk image to a smaller drive if the smaller drive has enough space to accommodate the occupied space of the larger disk (e.g. if you have a 200 GB disk with 100 GB occupied space, you can transfer image of this disk to a 150 GB drive, but not to 80 GB disk).

Solution

Resizing all partitions proportionally during restore:

(!) This can be done only with a backup of an entire hard disk.

  1. Create a backup of an entire hard disk that you want to restore to a larger or smaller one;
  2. Boot the computer with the new hard disk from Acronis Bootable Media;
  3. Restore the image;
  4. All the partitions will be restored proportionally to fit in the new hard drive automatically.

Resizing all or separate partitions manually during restore:

  1. Create a backup of entire hard disk or some partitions that you want to restore to a larger or smaller hard disk or partitions;
  2. Boot the computer with the new hard disk from Acronis Bootable Media;
  3. Restore the image. At the Partition or Disk to Restore step of Restore Data Wizard do not select and entire disk. Select a single partition and follow through the wizard. You will get a Restored Partition Size option, which you can adjust.

Sample scenario with Acronis True Image Home 2010

  1. Select Recover whole disks and partitions:

  2. Select a partition:

  3. Under Partition type, select Change default:

  4. Change the partition size by dragging the marker on the size bar or by setting the size manually:

       

More information

If the original hard drive stays on the same disk controller or RAID controller as the original hard drive, you do not need to apply Acronis Universal Restore. If you change the disk controller or RAID controller to another one, Acronis Universal Restore will be required.

If there is an issue with Acronis True Image not resizing the partition or not offering to resize, this may be due to the following:

  • There is a compatibility issue with encryption software installed on the machine. See Compatibility of Acronis True Image with Encryption Software;
  • There may be file system errors on the disk. Please run a checkdisk on the partition and then recreate the disk/partition backup and reattempt the restore with resizing:

    Go to the Command Prompt (Start-Run -> cmd);

    Enter the command:

    chkdsk DISK: /r

    where DISK is the partition letter you need to check. Please note, that checking the C: drive may require you to reboot the machine.
