I have been manually copying photos from my Mac hard drive over to My Passport Essentials. When I recently went to check the hard drive there were a year’s worth of photos missing but I am not sure how.
Is there any way to recover these files from the hard drive or establish why they might have been erased?
This is most unfortunate. In order to better assist, then a key question would be how exactly were you actually copying the pictures into your external disk unit?
Did this happen after updating the system to Mac OS Mavericks? There are several reports of the update erasing files from external disk drives from different manufacturers.
