Unlikely, but it might happen once in a blue moon - you might just have been unlucky.

how do you change the dvd drive, any tutorial for that
It's a straight physical swap, and doesn't need a tutorial.

ps ive got a dvd drive spare can i use it in the xbox
Only if it's a spare Xbox DVD drive. You can make a standard DVD drive work, but it's not simple, and it will never read Xbox games.
