ok i thought it was time to upgrade my hd again from a 80 gb to 250 gb so i get ready and then all i run my xboxhdm on my new hardrive but i couldnt find my c/e backups so i poweroff and i plug the pc hardrive in to get the files and it doesnt reconize it so....ater a few hours of trying to get it working i plug the 250 gig back in and it reconizes....but i though my ide cable might be going bad so i got a new one out of the garage and when i tried to plug in it i accidently bent the mother board pins for the hardrive cable.....fixed that with a toothpick bent em back in place...and THEN to top it all off! i bent the hardrive pins! so after i fixed that i gave up! im not doing that again for a longggggggggg time! lol
i wouldnt give up, jsut be more careful, maybe drink eat some food so you dont get the shakes and retry.
