Why, yes, some of them are pretty good (the above example is nice). I sometimes do, when I don't have anything nearby, and I just HAVE to shoot the moment. No big deal, why hard feelings? Nobody says it's going to be professional, but hey, sometimes it's not quality that counts.

In such cases, I'd create an image file of the SD card (with any USB Image Tool for either PC or Mac). The image file should be the same size as the SD card (like, 128 GB, even if card reader doesn't see more than 8 GB). Then one can recover SD card's contents (and see all those GBs that he can't see otherwise). I recovered my files with https://restore.media/ online tool, but there are other tools to recover them with, e.g. recover_mp4 or the like. However, the best way to keep SD card's contents safe is to format it regularly (before any important recording).

Though I'm a little bit late (almost 2 years late, that is), and topic starter has already solved his problem, I'll still put my 2 cents in. These things happen with old flash cards, so you have to be careful when you use them like too often (wedding video business count in), as it can melt down any moment. And the thing is, it's almost unrestorable - like, you will only be able to restore those 10-20-30% of your data before the crash happened. It's different when you have some physical damage done to your camera - this way your files can be recovered, as you have your data stored somewhere on the card, but it's marked as an empty space (this is the reason why you'd better not turn on your camera again if the damage happened - first recover your corrupted media - or this "empty" space will be overwritten, and your video lost forever). You should make an image file and restore it sector-wise - or send it to some good video recovering service, e.g. restore.media. Hope this might be helpful to someone with a similar case. Best of luck!
