I am having some issues with the built in HDD of my iMac so I started to copy files from the HDD to an external drive in terminal in Recovery mode.
I am using
ditto -V --norsrc "/Volumes/Macintosh HD/Users/USERNAME/Pictures/iPhoto-Mediathek.photolibrary/Masters/YEAR" /Volumes/NewHDD/iphoto/2014
It is working for some files yet it stops at a 200mb .MOV file after some succesful operations. I thought it would skip broken files and move on with other ones. Is there a way to "rescue", or parts of my 30GB of data in an semi-automatic way?
