DiskCopy is a free, portable program that does not require installation. It allows you to clone entire storage units or even specific partitions from one hard drive to another, even if the hard drive includes the operating system, programs and files. It will save an exact copy for emergencies. Download the program from the link below the post, then simply run it and you will see its simple graphical interface, where the storage units connected to the device are displayed.
Click on the hard drive you want to back up under Select the source disk and it will display all the available partitions on the right which are all selected by default, you can remove the check mark next to the partition you don't want to include in the backup or during cloning. Then select the hard drive to which the backup will be saved from the bottom half. Finally click on the "Start disk copy" button to start the backup
The program provides the option to convert the hard disk partitions to be copied from MBR to GPT or vice versa. The "Make the target disk bootable" option also makes the new hard disk ready for self-booting.
This tool will come in handy when you upgrade your device's storage from HDD to SSD.
