Okay, so i showed my buddy my soft-modded xbox and he wanted me to do the same to his. I like doing this stuff so i was quite excited. He told me his disk tray was not working so i though i would take a look. I had to replace a belt in the xbox but i got it working. However, the disk tray would not want to read disks. I tried to clean the laser but to no avail. So i opened up my xbox, removed my disk tray and stuck it in his. They were two different models but i was still able to plug it in, open the tray, and so forth. However, the xbox still wouldn't read the disks. So i ask the question, what could be wrong with his xbox? Edit: Bad title. "Broken CD Drive Laser"
