I am not looking to have an ide/sata adaptor or chipping a original XBOX. What is the biggest hard drive one can put softmodding one? Some people say 500GB and some say 750GB. I am looking for the hard drive that would yield the best results in terms of not overheating, speed, etc. Thank you. I am currently looking at a Seagate ST3750640A 750 GB,Internal,7200 RPM,3.5" EIDE PATA Hard Drive. I just want to make sure that I can use this drive without have to chip the XBOX.
