The Media Cloq Disks say "Protected by Media Cloq" right on the disks on near the bottom of the disk a little but towards the middle, There are only a small percentage of them and you can contact Sound Choice and have them replaced for $5.95.
I ran all of my parties from Backup disks after getting ripped off AND having disks go bad from drunks (including myself) handling them too much and not carefully enough.
contact them and have them replaced!
