What do you recommend for gratis (free of cost) software to clone a Windows boot drive?
The same software must be able to restore the cloned partition as well as the boot record.
I would strongly prefer software that can skip unallocated (unused) sectors. In other words, have the software be intelligent enough to recognize that a sector is unallocated and not add the bytes of that sector to the image. This is not a requirement, but if your recommendation can do this, please indicate that it has this feature.
