When using Linux, `/media` is often a reserved directory.

Specifically: `/media/derrell/8a40b384-ba80-4ede-99be-6e927897be79`

When this happens:

1. It creates a mount point under `/media/YOUR_USERNAME`
2. If there’s a label on the drive, it’s used, else the UUID is used
3. MOST IMPORTANTLY - exclusive access permission is asserted for ONLY your username.

Since this is a Pi, I suspect you’re using a USB drive for the media ?

If true, I suggest you mount the drive somewhere other than under `/media/your_username` to avoid permission problems.

Please see below (pay attention to the USB part)
