So Lightroom all of a sudden stop recognizing my external hard drive as something that was able to simple add photos to my catalog from. I have worked with the work flow of saving all my raw files to an external drive and simple add them to my catalog located on my computers internal drive for years now. This is very frustrating and I can't seem to find the answer anywhere. I am working with the Latest version of OS 10 on a 2014 MacBook Pro.
Any guidance would be much appreciated.
When was the last time you restarted your Mac?
Shut down your computer, disconnect the external drive, Start your computer and let it boot completely. Then connect the external.
Please state what the external drive is, make and model and whether it is USB powered or has an AC adapter.
