Error 36 message
II'm trying to copy my iphoto from one extetnal hardrive to another external harddrive. It comes up with Error 36, some data in the IPhoto library can't be read or written. The MacBook Pro is brand new so I'm assuming it has all the recent operating systems. The externa
harddrives e's are both brand new. I have no photos on the Macbook itself, only on the external harddrive. I'm trying to copy this for back up reasons. Whst do I do please. I'm very new to Macbbok and Iphoto so have no idea what to do at all.
Mac Pro, iOS 8.0.2
