Thus 67.1 x 1.024 x 1.024 x 1.024 = 72.1

Windows actually shows GiB strictly, not GB but calls it GB (historical naming).

GB = 1000 x 1000 x 1000

GiB = 1024 x 1024 x 1024

Yet, Mint shows a total of 72.1 +18.4 = 90.5 GB as opposed to 90.7 GB per Windows. Not quite a 1.024 cubed difference.

Most likely the difference is due to rounding errors. Doing math with numbers that are themselves rounded often results in results that are different and less accurate than if only the result is rounded. Of course we often don't have a choice.

You could be right. My point was only that I don't think that the differences shown have to do with 1 GB = 1,000,000,000 bytes versus 1 GB = 1,073,741,824 bytes.

Without a doubt they do - you are just seeing roundoff error in calculations.

OK then. The difference between

67.1 + 23.4 = 90.7
and
72.1 + 18.4 = 90.5

is just "roundoff error".

Thread apparently solved per OP, nonetheless.
