Is this legit?

[1234lol]

i've read that usb for xbox 360 doesn't support xbox game saves so so we can't update our 2k5 rosters with it but i found a page on yahoo answers with this: answersVyahooVcom/question/index?qid=20100428221655AAQIfNX
(replace big V's with periods)
so is this legit or is this guy dumb?

i haven't tried doing it b/c im too tired and one of the programs doesn't want to work for me so if som1 could test this out, i would much appreciate it
