First, I like to say hello to all board memebers as a new member. My DVD ROM driver kept telling me to insert a disk into drive "D" even after I inserted a disk into drive "D" (CD-ROM drive). It did not see video or hear audio at all. I even tried to play DVD manually but nothin happen. Couple months ago my son broke a CD Writer and I had to remove that CD Writer completely from the CPU. Can the DVD ROM drive work without CD writer drive? It is Samsung SD-616E DVD drive. Any help would be appreciated. It has given me big headache. Thank you in advance.
