Recovery doesn't work all the time because if the areas are overwritten the data is gone forever.
This is usually how folk learn we only lose what we don't backup. Backup often and to more than one place.
Hi, Guys! Unfourtunatly Ive formated my SD card thinking I have saved the videos were there. I send the sd card to a professional. He managed to recover most pictures but about the videos it showed only some kbs (wich is not enough for a video). So it seemed that he found the data or any information related to this video but not real video. I nether can open it... It is like It doenst have anything in the file....
Please if someone could help me
