I'm trying to trouble shoot a problem for my church. We use a multi bay dvd burner to make copies of Sunday Sermons for parishoners who cannot make it to that days service. recently a problem with this system surfaced when we couldn't open the doors manually by pushing the button on the front of most of the drives. the master bay works and one other writer will open, but the other ten won't. If there is a disk in the bay and it finishes its burn it will open at the end of the burn, but otherwise will not open. I find it unusual that this problem would affect so many drives simultaneously, and at first I thought it might be the controller card for the system, but I took each of the malfunctioning drives out and plugged them into another system with the same problem replicated. I'm begining to think that the system might have taken a power hit and the drives are bad and need replacing, but I am open to other less costly solutions if anybody has any other ideas. This sysem is being used by a small community church with limited funds so I am trying to keep the costs down. thank you.
