I've had this issue on my 360 slim ever since I bought the console and wondered if anyone else has had the same issue and knows if there is a fix. Its not been a major issue as I can get around the problem and dont fancy the hassle of packing it up and sending it back to Microsoft.
Basically if I have a CD in the tray and I load up a game I have installed on my hard drive this works fine. The problem I have is when I exit the game to go back to dashboard the screen goes black and the CD tray makes a noise like its trying to read the disc. The only way I can get around this is to make sure I have taken the disc out before playing a game on my hard drive. Unfortunately this also happens when I play games I have installed from the CD to my hard drive like Fallout: New Vegas. I have to open the disc tray to force it to quit back to dashboard.
This doesn't happen if I am playing a game straight off the CD.
When I bought the slim I transferred all the data from my old hard drive from my old XBox and I havent cleared the cache in years so I may try this but I wondered if anyone else had this issue?
