My Kodak High Performance 512MB memory card is only accessible with the RCA Lyra RD1072 mps player. When I plug the memory into my scan disk 12 in 1. I can no longer see my kodak card.

Try this link - they have udated drivers for your player, which hopefully will solve the problem;

Otherwise I would try and reformat your player (usually right-click on the player in "My Computer" should give you this option.

In "My computer" open the player and if the songs you are trying to delete are shown, then you may be able to just drag them to the recycle bin. worth a try.

Hope it helps if not please post again :)
