They are virgin and you have no reason to try erasing them, Or..... do you mean that you recorded some data on them and are trying to erase that data now and are getting the error message when you try? Look at your machine through System Profiler. Check the data under disc burning capability. That will list the methods of burning that your machine is capable of performing. I believe that you should not be trying DVD+RW discs at all. I remember reading something, somewhere, somewhen, that many of the burners installed in Macs at the factory should only be used with -RW type discs, not +RW discs.
