I bought a 128gb flash drive. I know Windows reads differently and I’ve read the generic answer the gurus in the forum give (https://petapixel.com/2012/10/10/why-hard-drives-and-memory-cards-have-less-space-than-advertised/). . )
However, using this conversion, the real capacity should be 119gb, not 114. Where are the other 5gb?
