Aperture keeps quitting when trying to make a vault
I bought a 1 tb EHD to used solely for vaults for my referenced library. I daisy chained the 1 tb EHD to my 2 tb EHD that has all my images. I have tried to make a vault 3 times now and aperture keeps crashing. Very frustrated, any thoughts? Their is plenty of free space on my hd to be used for the transfer. And the daisy chained EHD has its own power source.Thanks
