If you do not have enough space for your data, you can either replace the old disk with a new higher-capacity one, or add a new disk only to store data, leaving the system on the old disk.
To add a new hard disk:
Shut down your computer, and then install the new disk.
Turn on your computer.
Click the Start button —> Acronis (product folder) —> True Image —> Tools and Utilities —> Add New Disk.
Follow the wizard steps.
On the Finish step, ensure that the configured disk layout suits your needs, and then click Proceed.
