This is my first post,and hope that someone can help me. I have a Samsung DVD Rom-SD-612 that I never tried to Play or record until now, This drive will read a regular CD (audio or Video) with no problems. But when put in a blank DVD+R I get a message to insert disk and it cannot read the disk. I also get the same message after inserting a DVD movie. I would appreciate any help. Thank you. Catrambo
