Data is stored on the hard disc. The more memory hard disc has the more data can be stored.
The dubious disc is used to evolve PORYGON2 into PORYGON-Z a new version exclusive to Diamond/Pearl/Platinum. To evolve PORYGON2 make it hold the disc and trade to a friend then get them to trade PORYGON-Z back.

It depends...if you are burning data to a DVD-RW disc on a computer, and you do not finalize the disc then you may add more data later. However, if you are using a DVD-R disc then it will need to be finalized to access the files, and you will not be able to add more data without first erasing the data that is currently stored on the disc.
