Hey, thanks in advance for any help. I've been trying unsuccessfully for the past 24 hours to move my Aperture 3 library to an external drive. There's approx. 91 projects and 15k+ photos, 75% or more of which are RAW masters. Some notes: 2008 15" MBP 2.4 GhZ Core 2 Duo 8 GB RAM 500 GB 7200RPM hard drive My Aperture library is MANAGED which, to my knowledge, means this is a simple drag and drop operation. However, every time I drag the Aperture library to my external (LaCie Rugged 1TB FW800) the whole system freezes just after halfway through. I can open the portion of the library that transferred once I reboot but nothing seems to be there, photo-wise, past a certain point (as in only a portion of the photos transfer but the data stating that the photos existed still moves). Any guidance would be appreciated, getting a little frustrated with this process.
