Tried for a couple hours on the weekend to get a Pioneer BDC-202 optical drive to work off of a DH77KC. When connected to SATA 0 or 1 it is not detected at all, when connected to 2, 3, or 4, it is detected but the tray hesitates when opening/closing, takes an eternity to just catalog a disk, and constantly makes a grinding noise even with no disk inserted.
The same drive was then tested in several other PCs, including a Q75 based HP, and worked perfectly.
Any thoughts at all?
