Hello,

I have a San Disk Extreme Portable SSD with 1 TB capacity. There is no data hidden in invisible folders. There are 540 GB of data on it.

But: The Finder and Disk Utility show that 797 GB of data are used on the SSD. Only 202 GB are shown as free capacity.

– Why is that?
– Where is the remaining space (258 GB)?

– How can I release and use the missing memory?

Please see image for details.
