Wanted to relocate Masters from IMAC to External HD to free up IMAC space.  Went to “Photo” and selected all of them (thousands) and went to bed.  Started out fine and is now stuck about half way.  It’s been 24 hours and it’s stuck on one JPG!

What should I do?  FORCE QUIT?   I don’t want to loose anything!

THANK YOU!!!!!!

Information: 

Aperture 3

New HD is 3T.  It’s a Western Digital

IMAC has 2T and becoming too full because of Aperture 3 raw/jpeg fine files.
