moves the content of hard disks on a physical level

The Free Edition of HDClone is the ideal tool for moving contents of entire harddisk drives onto bigger newer ones. It can be installed on floppy or cd (ISO image included). It ships with its own operating system and is therefore not depending on other installed systems. When buying a new larger disk, HDClone copies the data for you, you only have to add the gained space on the disk via some partitioning tool.
