wth
I wasn't aware my post came out like that.. like I know "evrything"... the reason why im asking all these questions is because i DONT know the answer if you can replace a drive or not.
I'm just confused... lets say your ms28 gets bricked.. why cant you just get another ms28 and use it in your 360?
I'm not sure what you're trying to say either.. you forgot to use punctuation in some areas... are you quoting me or did you reply to my questions?
Let's say you loose the key for an ms28 drive on your 360, i assume that drive is bricked... why cant i just get another drive (ms28) and use it?
Sorry I worded my recent post wrong... that wasn't my intention at all

If your drive is bricked, you can replace it with ANY other drive that runs hacked firmware!
You NEED to HAVE the original dvd-key that was stored on your drive that came with the xbox!!!!!!!!!!!!!!!!!!!
If you do not have that key, then you turned your xbox in an expensive home-dvdplayer!
an MS28 is detected as an ms28 but the key is the missing link. let's say you want to replace it with a hitachi 59dj, you need to spoof that hitachi as an MS28 (otherwise E65 error) AND you need to put the right dvd-key in the firmware (otherwise you cannot play games)
