Hi.. the system will hang when the cd is not connected as there is no termination.. You could enable the termination on the hd itself or use an internal active terminator 50 pin scsi2. Or if you have an external port connected to the warpengine then an external active terminator.
I doubt any lvd terminators would work properly.
I don't actually have any scsi devices on my warpengine so i can't confirm, but on my pc server i have an external terminator for the external port for when i don't have a dat or cd etc... connected.
