Here is a way to make low density disk into HD. Buy a sauder gun. Get a high density disk and stick it with the low density disk. Make sure they are facing the right way. EX. heads on top of heads!!!! Now make sure the sauder gun is hot and punch a whole through the top let corner. Notice how the low density disk don't have this, and the high density do?? Well punch that whole and format the disk!!! Now you have High Density disk.... Save money!!!! But make sure the kind of low density disk you have has a square box in the the top left corner. Mr. Hilt
