    Cannot export as catalog to external drive

    tracys66364935

      I export each year's photos as a catalog to several external drives to make space on my hard drive.  I got a year behind so I am doing 2015 & 2016 now.  The other day I exported 2015 and it seemed to work fine.  Now I am trying to export 2016 and LR won't create a catalog.  It did copy all the photos and folders to the external drive.

       

      I tried to create the catalog and got an error message saying that "Lightroom cannot create a catalog named "2016t" on volume "Volumes/Photobackups by year/2016/2016t" because Lightroom cannot save changes to this location.  Lightroom Catalogs can not be opened on network volumes, removeable storage or read only volumes."

       

      I tried to open previous years' catalogs and got an error message stating that LR had encountered an unknown error.

       

      I am using LR 4 (no update available) on an iMac.  It is a WD external drive.  Lots of room on both hard drive and external drive.  Any ideas of what I can do to fix this?
