I looked around here and I don't see this exact problem( similiar ones but not the exact problem): I had a hp pavillion with XP and I put music and photos on a cd-r disc. Now I have a new hp pavillion with Vista on it. I can not read my cd-r disk on the vista computer. Actually its not one cd its many. They are still readable on the old computer. The new computer reads store bought cds and dvds. I have seen many people having this trouble but no solutions. Also One guy suggested the disks were not finalized is there anyway I can finalized them now with either my old computer or new computer? Anyone able to help? Thanks a lot if you can help.
