I have a 67gb SD card in my samsung phone and i have photos and videos saved to it. Recently, i moved some videos to from internal storage to sd card and they seemed to be corrupted. I also copied some videos from a camera to sd card and a lot of them also became corrupted. A few of the videos and pictures i take with my phones camera and automatically save to SD card seem to have been corrupted too.

Is there a way for me to stop this from happening? Should i start backing up my data and switching to a new sd card?
