My Garmin Edge 310 has eaten 4 ride files, they are all zero bytes when attached as a storage device. Is there any hope of getting them back? Well, one I would like, the other 3 don't matter. All 4 exist in the ride history list (date, duration, start time & distance shown) but if I try to open them they are empty as you'd expect.
Has anyone had any success using some kind of file recovery software on a Garmin?
[ETA] I know the routes got recorded OK because after I finished & saved the one I'm interested in recovering I went back into it to check the climb total, now lost. It was later the corruption happened. I suspect the Connect app screwed something up in a sync. I've just found that several courses on the device, including this one, are also corrupt.
