My flatmate managed to spill liquid on her xbox slim 250Gig. We switched it off and left it for 48 hours to dry. Tried it after 48 hours and it worked fine and the hard drive was fine. 24 hours later tried to switch it on again and it wouldn't switch on, it would make the noise when you pressed the on button but wouldn't switch on.
I'm going to buy another xbox slim tomorrow and wondered, if i put in the old hard drive will old saved games and gamertag etc still be available? Or is there a specific procedure i'll need to follow to recover them?
