I, like many people, got the new Xbox for Christmas. However, my mom failed to notice that it was the 4GB model, rather than the awesome 250GB. When I realized this, I immediately went online and looked for a 250GB Xbox S Hard Drive, and found that they're $130($0.52/GB)! Well I knew that the Xbox can use flashdrives for storage, etc. so it should treat an external hard drive just like a big flashdrive, right? So I went to BestBuy and bought a 500GB external hard drive for $60 ($0.12/GB- 4.3x cheaper!). Upon plugging this into my Xbox, and going through the configuration process, I see that my Xbox is only picking it up as 16GB. "Are you kidding me? There's a lot more than 16GB on that thing!" I went online, and did some Googling, and YouTubing. All I could find was formatting the drive, and even then only being able to transfer movies, music, etc from you computer. I read multiple times that you couldn't put games or profiles on it(I wanted to do this, so I could transfer everything from my old original Xbox 360 HDD, and then sell it). Could somebody please tell me a way to make an external hard drive work with Xbox 360? I'd rather not format anything, but I will if I must. Thank you!
