It's a USB connected GoPro camera that has an SD card in it. I have some videos on there. How can I access my data? How can I mount them as an NTFS/FAT32, or other eligible way to access it? See the attached images for more info: Showing filesystem: Showing data type Which data only showing: lsblk Data: lsblk -F data:
