I wanted to back up some info onto a CD but am unable to because the CD drive will not open. The drive does respond to the request to open but the tray fails to appear. I have windows XP installed. The drive has always opened in the past. There are a few suggestions in the columns on this forum on ways to tackle this fault. I do not know which to pick and would appreciate guidance as to how I may solve this problem. Am not very pc savvy, sorry.
