"please insert an empty disk"

i keep getting this message when i’m trying to burn a DVD. they are Sony DVD-R’s on a HP a475c computer. i believe the dvd writer is a samsung.

i put a DVD-R in the drive, go to my computer, and i double click the drive and it acts like nothing is in there. what do i do? how do i burn these dvd’s?

please help!

need more info, what are you trying to burn to them ? with what software ? why are you double clicking on a drive with a blank in it ?
