If a chunk of it is used for other data then take that extra off the marketed capacity.
That'd be confusing...since it depends on operating system and file system.
Maybe an 'estimate of formatted capacity based on windows'...who knows? who cares? The cost per GB is insanely low even if you factor in the decimal vs. binary difference
My first Amiga HDD was 85MB and it cost hundreds of pounds..but I think they were decimal MB too
