Extra details

  • My thumbdrive doesnt show up in the file manager even tho the diet pi drive manager says its online and ready for use. It shows up on both the terminal and the diet pi drive manager. I am using lxde but I don’t think it is an issue with lxde since I installed xfce and the drive doesn’t show up on there either. I have tried rebooting multiple times and nothing changed.

I am kinda new to linux so I may have made some mistakes. Can anybody help me with this? Thanks.
