Lite On Dvdrw Shw-160p6s

I need to back up some pictures and other things but after inserting a blank disk my machine tells me to insert a blank dis any idea why?

I have LITE ON DVDRW SHW-160P6S installed and it will read data and music discs unfourtanetly I don’t have any dvd’s so I’m not sure if it will read/play them.

I’ve used the drruive to burn music among rther files in the past but as of about December of last year I get the please insert blank disc when trying to burn to a disc.

Any answers and help to get my device working properly again is greatly apreciated.
