My bro was playing COD: WaW and some dude sent him an invite to a game so he joined then it said "could not join game" or somethine along those lines (i wasnt there) then he said he turned off the console and tried to turn it on later and it wouldnt work it kept giving him some error code (e68) or it wouldnt have any profiles or save data. I have tried all kinds of "fixes" such as
unpluging av cable
switching to hdtv then back
lovingly tapping the hdd on something hard
beating the crap out of the hdd

and it still does the same thing. i took it apart but couldnt find a screw driver small enough to get the screws out of the actual hardrive (i got the torx out tho) i know my way around hardware fairly well so if there is some way to repair this my self i would greatly appreciate it.
p.s. i have the gamerpic for beating mass effect on insanity and i really dont want to have to beat the games 3 times in a row again

plus i dont want to have to buy a new hdd.
