When i open My Computer, I see the D: and E: Drives there. I insert a CD it will see it, if it is a music cd and opens the default player. If I close the default player and try and double click on the D: or E: drive to open the cd, it will not see it and tells me to insert a disk. What can I do to fix this? I have had this computer for 12 years and it started acting up when I installed a external dvd player/burner made by LG. I took this dvd player/burner off, and this is how the drives are acting. Its like the DVD player changed the settings or something. Any advise would be appreciated.
