finder – Discrepancies in disk utilization on exterior ssd formatted as exFAT

I’ve an exterior quantity (an SSD by Sandisk linked through a usb-c cable) rated at 1TB. Finder says the disk is full (when I attempt to add a file it errors with: No area left on system (28)

Finder "Get Info" on external volume

nevertheless once I take a look at the sizes of the directories on the exterior quantity, of which there are two, one known as Films and the opposite TV, the sizes don’t add up at ALL:

Finder "Get Info" on external volume/Movies

Finder "Get Info" on external volume/TV

including these two folder sizes provides as much as a bit of over 700GB and nowhere close to the 1000GB used as claimed by “Get Data” in Finder on the amount.

Now I understand there could possibly be hidden directories which might be hassle so I checked out these utilizing Cmd+Shift+. as you may see within the following screenshot:

Finder hidden folders on external volume

The one listing (of these hidden) that has greater than 10MB is .Highlight-V100 as might be seen right here:

Finder "Get Info" on external volume/.Spotlight-V100

Perhaps the dimensions on disk right here is definitely a lot bigger than reported?

To resolve issues I additionally approached it from a special angle and ran the du and ncdu utilities within the terminal, the output of which is once more connected right here:

ncdu Output
du Output

These outputs lead me to consider the sizes of Films and TV might be kind of trusted, nevertheless for .Highlight-V100 and .Trashes sadly there appears to be no or flawed information for a permission challenge.

I’m out of my data right here – perhaps that is an exFAT particular drawback? Ought to I strive delete the Highlight listing as a primary step?

Any assist a lot appreciated! 🙂 Additionally if anyone wants any extra knowledge, simply remark. One final picture of the information output from disk utility:
