"This memory card was burned in a GoPro that overheated" Matt Greenwood, founder of Nandoff Data Recovery, told me, as he pointed to a digital microscope to show me the remains of a MicroSD card which, to be honest, I would probably have discarded. He had been able to get all the data off it.
Matt is at The Photography and Video Show with a small booth talking to photographers about his services, but after nearly two days of the four-day event, he tells me that the majority of photographers – at least of those he has spoken to – admitted they had no idea at all that it was possible to recover data from chips so badly damaged.
