My 360's Toshiba / Samsung drive stopped reading disc media. I tried using lens cleaner on the lens, yet it has been ineffective. I found and ordered a BenQ replacement drive....but have I just wasted 70 dollars? I have seen some discussion of "drive keys" or something of the sort. Can you not replace the drive without some god-awful complicated mess? I wish I had kept my PS3....never had any problems with it. These problem-prone 360s are starting to annoy me with how much time I have to spend attempting to fix them. Please let me know if there's anything I can do. P.S. in a fit of rage I trashed the Toshiba-Samsung drive. I was very upset.
