Newb here trying to get started on a Blue Iris set up. I purchased a refurbished HP EliteDesk 800 SFF G4. It has an optical drive and an SSD drive. I also bought two WD Purple drives to install in the two available HDD slots. Today I started trying to install the HDDs and figured out that there is no spare data cables to attach to the drives although there is a power cable for two HDDs. The computer has three connectors on the board. Two of them are being used by the optical drive and the SSD. I have been trying to figure out a data cable to buy but am wondering if there is only one connector on the board and I need to connect to two HDDs, how is it going to work? Do I need to unplug the data cable from the optical drive and use it on one the HDDs and then get a new cable to use for the other HDD? Is there any kind of data cable that has two heads so that you can use one cable to attach to two HDDs? I haven't been able to find any such thing. Surely there is a way to have two HDDs, an SSD and an optical drive in this machine. Thanks for any insight or ideas.
