Sometimes that is not enough. Some programs also check things such as 
CPU ID, and other serial numbers.

"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?)
