to clarify what you are asking: are you looking to simply clone the drive for use in another mac? or to use and run on a pc?
i took it at first as you want to clone an OS X drive to work on a windows pc. but now i am reading it as you simply want a program that will let you clone the drive from windows.
which way is right as i confused myself
this will let you access the drive in windows. i've used it in the past and it's good for 15 days so you have time to tinker a bit. i did not clone a drive with it but i did access files and make an image multiple times using it. it may clone as well.

linux will natively read the drive if you have a distro but i have no idea how to clone the drive using it. but it will let you access the info easily enough natively.
