Cannot access files on ext-4 usb drive

[Ozdemon]

I gave my f-in-l a Khadas media streamer in 2020 together with an ext-4 usb drive with home videos. He is visiting and I wanted to add some more videos. The drive shows up in my Dolphin file manager but no files, i.e. the usb drive appears to be empty (which it isn’t). Gparted shows no errors.

ls -ld /run/media/tpb/nevs-videos
drwxr--r-- 8 1000 autologin 4096 Apr 13  2020 /run/media/tpb/nevs-videos

Can anyone help on how I access the contents without affecting permissions when he re-connects to his Khadas box?

[Tutorial] Working with additional 'drives'

Difficulty: ★★☆☆☆ 1. INTRODUCTION Microsoft Windows started its life as a graphical user interface on top of MS-DOS, a 16-bit single-user, single-tasking operating system that in turn originated as 86DOS, an unauthorized 16-bit rewrite (by Tim Paterson of Seattle Computer) of Digital Research’s originally 8-bit CP/M operating system. Both CP/M and MS-DOS were at the time developed for computers that did not support any other storage media than floppy disks. Considering this legacy, Microsof…

This is a tricky question - in short you cannot - you will somehow affect the khadas box - to what effect is unknown

@Ozdemon

1000 autologin

On your system

UID=1000
GID=autologin

Without execute permissions one cannot read the content of a folder.

The user 1000 is not assigned on your system but a group named autologin exist.

One possible solution is to ensure you have a user with UID 1000 - which should make it possible to read the stick.

grep -e '1000' /etc/passwd

It may be as simple as changing the toplevel permissions from 744 to 755

sudo chmod 755 /run/media/tph/nevs-videos

@ManjaroDevOps

sudo chmod 755 /run/media/tph/nevs-videos

Thanks, aarhus, that worked!
