I have a Dell Inspirion 1525 and the dvd drive doesnt seem to work...first it doesnt open on its own we have to push the pin hole in...once it's open and we put a disk in it keeps saying to insert a disk...is there anything we can do or do we just need to get a new drive? If we need a new drive what drives are compatible with our computer...we want somehing we can use to burn cds and dvds.Thanks for your help!
