Josh's computer "went off the rails" when he did RoboCopy and wiped his hard drive. So now, he needs to talk about data recovery on his hard drive. Leo says that if there's a software issue, or if you deleted a file, the data is still there until you overwrite it. Leo recommends RECUVA. But if the data has been overwritten, you really can't get the data back, not even from Drive Savers. This is why you should always back up your hard drive, ALWAYS.
Mark's mom accidentally deleted all the images on her Samsung Galaxy S5. They were able to get photos back with "Disk Digger," but what about the videos? Is there any way to get them back?
Mark accidentally deleted photos from his Android phone. How can he get it back? Leo says he can do it by mounting his Android device to his computer and put it in MTP mode. Then he can use an undelete utility to restore the image. There may also be an app in the Google Play store that can do it. Mark should turn off the phone and do nothing with it until he's ready to restore it. Connect it to his computer and use apps like Install Image or Disk Digger.
Rob was using Adobe Premiere to edit his video, but he ran into problems when his external hard drive gets unplugged. Leo says that if a hard drive suddenly gets disconnected, OS X doesn't like it. Modern operating systems use a journaling setup that will save up a bunch of data before it writes to the hard drive. That's why OS X wants him to eject the drive first before disconnecting. When he disconnects while the hard drive is writing, then the hard drive writes a kind of 'word salad' to the hard drive that could corrupt it. He'll need some recovery software that can fix the file table.
Paul has an LG G3, took his memory card out, put it on another phone, and now it won't mount. Leo says it's probably a format that isn't read because the other phone is older. Now he can't get the data because the older phone damaged the card. Leo says that he can get a program that can read it called Recuva which is free. That should be able to get the data off. PC Inspector will also do it.
