    Lightroom can't see my external hard drives.

    Marie34

      The external hard drive I have had for a year has been filled up so I bought a new one. I have both attached to my MacBook (thunderbolt display if that makes a difference} I now have the dreaded ! on all the images on the old drive but I didn't do anything other than eject it. I've read various fix suggestions but none of them seem to work.  Any help will be gratefully accepted, preferably in very simple terms.  Thank you.
