I used CopyToDVD to backup some data and after finalizing the process I inserted the DVD back in to see if It worked. My DVD RW drive started to read it but nothing came up for awhile then when it finished loading, there was nothing inside. The size on the disk read 0 bytes. I tried it on a laptop and the DVD worked fine. Why is that? I just got the drive today, it's a NEC ND-2510A.
