    I have a Mac Pro 2008 and I have three harddrives in it. As these are filling up, I decided to get a fourth drive and install it.

    Only problem is that it does not show up.

    At first I thought it might be the drive, but when I changed two drives around, the new drive shows up and the old one does not.

    Have anyone seen anything like it and / or have a tip as to what I should do?

    I expect that it might be a faulty interface, and that I am stuck with three drives max in it.

    Do you still have AppleCare?

    Also check if the slot has any obstructions? Maybe try the HDD in your second optical drive bay assuming you don't need a second optical drive?

    Thank you for your suggestions.

    No Apple Care left here, and I decided to just swap out the smallest drive here and go with "only" three drives. :)

    Check to make sure the tabs that hold the connector at the back of the HDD bay (one not working) is bent out of shape or not (two aluminum tabs hang down (90 degrees), and there's a phillips screw through each holding a backplane connector = data + power).

    Barring that, it could be the cable or logic board.
