im just worried that it might corrupt my files or something

you shouldnt have to buy any. i have 34 of them and i havent spent any money on them. you can find them all over the place in the game.

i got two 360s that i use, but only one hard drive. i was just wondering if i could possibly damage the hd by detaching and reattaching it to each system, and if so, would it be worth it to buy another harddrive or should i go for a memory card? i was also wondering how you can transfer things from one hd to the other.

man mine broke and i sent it in sept 5, then i went and bought another one. the new one just broke today. i gotta send that in now. hopefully though i should be gettin the first one back monday, just in time for halo
