First what is your system specs?
Does this problem occur with one disk, one disk type ie. CD-R, CD-RW, one manufacturer, or does it happen with all that you use?
I think I had this drive at some point but am not 100% sure if it was the same model. If it is, mine started showing similar problems, unfortunately for me it just went down hill from there on. In the end it would not read game disks, if it did it was after I opened and closed the tray many times. Maybe try different media and make.
