>I booted up under Linux and used dd like I should've in the first place.
Congratulations on catching on to the solution to a problem the rest of the world fixed more than forty years ago. This experience of a release from frustration is common to people who learn how to do something under Linux and discover there is enlightenment to be had after all.
Also, as another truism more than forty years old, never look to a hardware manufacturer for a software solution. That's just begging for misery.
Also, also, in a word, Clonezilla.
