Notebook doesn't recognize Blank CD/DVDs

Hi,

I just bought a Dell Precision M2800 (early 2014).

I can play DVDs and CDs normally but I when i put a blank CD or DVD to burn it, it doesn't recognize it and tells me "Please insert a disk in the DVD drive". I tried many solutions from this forum but none of them worked for me. I tried burning the same DVDs and CDs in others notebooks and they worked perfectly.

Please tell me what can i do.
