Have you tried to make the disk with CopytoDVD? You say you used Nero. if you did use CopytoDVD does it do the same thing?

yes i did use the copy to DVD option.

I guess I didn't ask the question right, you said you used Nero and the disk is unreadable, Nero is an application created by Ahead Software. Copy to DVD is another application created by VSO Software. The way your question is written in both posts comes out to this as I read it.."Using Nero I created a data dvd, using the dvd option in Nero, after using Nero to create the data disk, the disk turns out to be unreadable in my other drives, does anyone know whats wrong?" thats what I come up with, please correct me if I am wrong.

your are right,thats my question can you help me.
