When erasing discs you usually have two options: full and quick erase. Full erase, as its name implies, means that all data will be deleted. Quick erase deletes only file system information; it does not delete the data itself, so if you want to securely destroy all previous information, you should choose the full method, otherwise the quick method is the best, because it works much faster.so the regarding damage of the disk depend's on the usage and not in full and quick erase.....
