I/O Magic 8x DVD +/- R/RW won't write discs



i recently reformated my harddrive and reinstalled windows xp sp2 on my cpu. prior to me doing this, my writer worked fine. no when i try to burn any dvd or cd on it, it asks me to insert a new media and once i do, it asks me again and again to do the same thing and doesn’t burn anything. i’ve already tried to switch from master to slave ide, reinstall the software (nero 6.6 and roxio 7) and reinstall the burner through my system properties and nothing has changed.

please help!!
