Most hardware-based cloners typically require for the destination drive to be the same size as the source drive even if only a fraction of the space is used. For example, the filesystem and partitions can be resized by the software allowing data to be cloned to a drive equal to or greater than the total used space. However, software cloners tend to allow for greater flexibility because they can exclude unwanted data from being duplicated reducing cloning time. A hardware-based drive cloner can be used which does not require a computer. Once connected, a disk cloner is used to perform the clone itself. Typically, the destination drive is connected to a computer (Fig.

The data is then either written directly to another (destination) drive or to a disk image. A small amount of data is read and then held in the computer's memory. While called 'disk cloning', any type of storage medium that connects to the computer via USB, NVMe or SATA can be cloned. Figure 1: An illustration of connecting two drives to a computer to clone one drive (the source drive) to another (the destination) drive.ĭisk cloning occurs by copying the contents of a drive called the source drive.
