Plextor 716AL cannot read disk it just burnt

When I burn a disk using Nero and attempt to read it using the Plextor 716AL 1.02 FW, it says there is 0 data on the disk. I put the disk into another computer with a Plextor 760A and it reads the disk just fine. Any ideas?

What kind of discs do you burn?

It was a DVD-R disk. Also when I put the disk back in I noticed that the drive’s status light just blinks orange. Does that indicate anything?
