Hopefully I won't need help with replacing this drive. Instead I thought I would relay an experience that occurred tonight. I put a software ap CD in the drive and it shattered the CD as it was closing the door. I got 3 pieces of the CD out and I assume the rest of it is in the bottom of the tower. (There are no pieces in the tray.) I'll know tomorrow when I replace the drive but I suspect there may be more to it than just that. What may have caused that to happen may be anyone's guess. The door to the drive keeps opening and trying to close even as I type. Just relaying another of my "can't believe computing experiences". Of course, you may have ideas about this and if so, please reply. As usual, TIA.
