A while back when I bought my first Arcade, I was bugged with the measly 20GB HDD I had so when it was available I turned a 320GB Western Digital drive into an Xbox 360 HDD. I had files that I presume were for restoring it but I deleted them since I didn't think I'd need to change it back. I'm wanting to use it for the new RGH I have but I don't want to keep it as the main drive, just an external USB that I can put games on. Does anyone know if it's possible to change it back to a normal hard drive without the files?
