Paul backed up his 16GB microSD card to his computer, and suddenly he's getting errors and can't see the card anymore. What can he use to recover the data and then back it up? Leo suggests PC Inspector to recover the card and then Helium to back it up.
Wally has a corrupted SD card and while he can get videos off it, they can't be played. Leo says that if the video file isn't complete, there's a good chance he won't be able to play it. There may be software that can rebuild the corrupted video, but what he really wants is to get every bit of the data off every sector. Leo uses Recuva by Piriform. It's very good. Then, open the files in VLC Video Player. It's the least vulnerable to file corruption issues.
Paul has a lot of movies on an external hard drive for the kids to watch, but the drive accidentally got formatted. Can he recover it? Leo says a simple erase doesn't really erase the data, it just makes the sector available for re-use. A format is more complete, though. That doesn't mean it's unrecoverable. Leo recommends Recuva. If it can't save it, nothing can. It's free, but he should make sure to get it from the original source. He should also be sure to enable the deep scan option.
