I've got Windows Xp which i recently reinstalled. For about the first week the drives were reading now when i put in any DVD/CD i get an error saying: the disk is not formatted or it is corrupted and windows cant read them. when all the disks i put in were working a week ago and are in the same condition no scratching or dirt/dust. With a fresh restart any rejected disk is occaisonaly read but when i put in the next one in the same session i get the error stated above. What do i do?
