Mathematica on raspberry. External media access. I have a usb harddisk, which is recognized by the system, but apparently not known to Mathematica. The disk is not seen when I try to open files from inside Mathematica. But I can launch Mathematica from the files (right clicking etc). How do I make these media known inside Mathematica. Observe I am almost without experience in Linux.
Copy a notebook to the USB disk. Open this by double clicking. Evaluate in the notebook window the function
NotebookFileName. If all is well you should be able to infer the disk name from the result.
