I’m working on an NVIDIA AGX Xavier which is running 4.9.140-tegra.
When I plug in an external USB drive (formatted as exFAT), it will sometimes be mounted in the user folder as /media/USER/ssd1 and everything writes and reads correctly. Though, it will sometimes mount as /media/5FA5-1920. When it mounts in this way, writing will not work correctly. For example, attempting to rsync to that device will result in errors such as
rsync: chgrp "/media/5FA5-1920/Log_dump" failed: Operation not permitted (1)It will continue to “write” but at the end of the operation, only the directory structure is present, none of the files.
Here’s the DMESG:
