    Sounds like it might be a known E450 problem.
    The disks plug into backplanes which can flex, leaving the disks
    only partially connected. The backplane mounting arrangement has
    been modified several times to fix this, early models are the
    worst.

    Shut down and remove the RH side cover.
    Unlatch all disks and slide out a few inches.
    For each disk in the central stack, support the rear of the
    backplane with your hand and insert the disk whilst watching
    through the side of the cage to ensure that the connector seats fully.
    Some fiddling and/or moderate force on the rear of the backplane
    may be needed to make sure that everything aligns correctly.
    Repeat for the outer stack.
