Sometimes that is not enough. Some programs also check things such as CPU ID, and other serial numbers.I want to make an exact backup of a hard drive (copy one drive to another). It contains a program who's copy protection checks changes to the system so unless I can restore it exactly the program will stop running (it's a veterinary clinic software so I don't think that there is a free alternative) Thanks
"dd" or "cat" is probably sufficient, but you will get a file that is the SAME size as the HDD.
So, I would get another HDD that is *exactly* equal or larger, and use the actual hard disc as the destination file. (ie, /dev/hdd)
(Could someone else please confirm this?)
