I see your point, perhaps a generic "how to install a hard drive in an A600/1200/4000" would be better though? The CF part is only a small variation, as there's very little to do apart from plugging it into a the adapter and setting it to master/slave (which is no different than on an IDE hard drive, so again would be covered in the generic guide.)
Might look into making such a guide tomorrow, if I have time.
