NEC DVD+/-RW ND-2500A problem

[qanda]This thread is about the NEC ND-2500A. Click here to see full specs[/qanda]Well, here’s the problem.

I have recently decided I want to save part of my stored files on my computer before I wipe it clean and reinstall the OS, and bought myself a 50pk of Memorex DVD+Rs for this purpose.

Now I haven’t used my DVD burner for burning DVD+Rs or DVD-Rs before, only CD-Rs and CD-RWs, which worked fine. But when I put a DVD+R in it registers as a CD Rom and states that there is no file space on the disk.

I’m running Windows XP with Service Pack 2

Can someone help me?
