I am unable to export my catalog to a USB attached drive. Watching the message bar it appears the catalog is created with all of the reference pointers, data, etc but then as the negatives are being copied it crashes a minute or so into the copying. I've watched the files being copied and it doesn't fail on the same file. I've made more room on the HD (it has 600 gb free so that is not the problem). Any ideas.
Problem solved. I shut down the CC Cloud connection and this worked fine.
