Is the drive flashable?
Yes. You will need some style of PMT probe to extract the key. Read the JungelFlasher tutorial for info.
Do I need a special burner to make backups with if it is?
Proper XDG3/AP25 backups will require an iHAS RevB burner.
Or is RGH the better option,
Depends on what you want to do. Check this: http://forums.xbox-scene.com/index.php?showtopic=718103
JTAG and RGH are different hacks that achieve the same result.
and if so, is there a service offered to have this done?
Check the BST section of this forum.
