    Running Mavericks on late 2009 27" iMac.

    Had 1 external drive on firewire and q on USB reining perfectly.

    Installed security update 2015-002 and now both drives are missing. Plugged into other mac and they're fine but just can't see them on this computer.

    Any help please?

    (I've run all usual repair permissions, reset pram, etc).
