This day is an absolute disaster, like I can't remember. After spending time with my computer guru about a back up problem, he suggested the most likely solution would be to move one folder to an external drive to save some space. I did, then checked the external drive to ascertain everything was in order. It was, so I deleted the folder from the PC. Went to do something else with images this morning and the external drive is empty. I have lost every photo from our years on the road. Thousands of them. Six long trips all over Australia and eleven shorter ones up and down the east coast, to SA and a six month drive to Darwin, covering about nine years. I have a card recovery program but it only works with camera cards. Doesn't work with a drive. Is such a program available for an external drive? Does anyone think there may be chance of recovering them. I am shattered. Noel.
