HD Clone is a free hard disk cloning program which will let you create and store an image of your disk in case of problems or failure. This sort of tool is uber useful for migrating your data to a new hard disk, or for restoring your stuff if your hard disk crashes and burns. I use True Image because I’ve had it for a long while and I trust it, but free is a hard price to beat (although to get the full feature set -e.g. cloning to smaller disks – you really need to pay money for the HD Clone Standard and Pro editions).
The Free Edition of HDClone clones an entire hard disk to another, larger medium. Use it for migrating an existing installation to a new hard disk or for rescuing data. The Free Edition is real freeware without obligation to buy and is intended for the short-term usage at no cost. In case of more frequent usage, we recommend using one of the higher editions since they offer higher performance, support for a wider range of hardware, and additional options which are optimized for regular or professional use.
