This has me perplexed.

The /media directory seems to be treated differently by the system. I've
tried to change ownership / permissions on a test drive and it's not
behaving as I expect.
I'm able to make those same changes under /mnt so I'm missing something. I
need an up-slap to the back of the head, a far stronger cup of coffee or
probably just a hefty dose of RTFM. In the meantime, I'll blame systemd :P

If you don't want to relocate that drive (understandable), and you have a
spare USB slot then I'd be plugging a fresh drive in under /mnt and
mounting it via fstab. You can then manually set the permissions to weewx
and they'll stick.

And, if someone knows the answer. I'm all ears

Cheers
