One of the major hurdles in disk cloning is driver incompatibility. If you clone a drive from an Intel-based system to an AMD-based system, the boot process often fails due to driver mismatches. HDClone 4.2.2a includes mechanisms to help adjust the cloned system to new hardware, facilitating smoother migrations between different machines.

When cloning from a smaller drive to a larger one, HDClone Professional can automatically expand the target partition to fill the new space. Conversely, it can shrink the source partition to fit a smaller target drive, provided the used data fits.
