I just got a 120GB Elite 360 from my friend & got all setup on XBL but I have few questions & can't seem to find any solid info on them. I would like to put a western digital 640GB HD in my HD caddy, is it possible to have that work in a 360? I know that the 360's HDs have proprietary software that has to be on the disk for it to work but I have also heard there are some ways to work around this & use any 2.5" SATA HD with the 360. Also I have to figure out how to disassemble the 120GB Elite model, clean the dust out of the case & off the electronics, & change the t-paste to some MX-4. I have done this many times with the PS3 & have seen many guides for doing this to the original 360 but can't find much about doing this to an Elite 360. Any & all help is greatly appreciated, thanks in advance guys.
