Thumbnail only, no back-up
I recently reformatted a MBP (2 years ago) and have just gone through some of the photos on a backup EHD and it appears only the thumbnails are visible, not the actual photos.
Is there ANY possible way of getting the data/image back as I no longer have the MBP (Sold it to a friend) and it appears the back up is only thumbnails. There are some really important photos on there as something recently happened family wise and really would like to get them back. Surely there must be some technical way that isn't usually advertised as the data of the image is there in the thumbnail?
Any help greatly appreciated. Ian
