GoKawiilWhy a 512GB drive shows only 477GB usable in Windows
Storage drives often display less capacity in an operating system than their advertised size, with one tested 512GB drive registering just 477GB accessible in Windows. The roughly 35GB gap mainly stems from differing methods manufacturers and operating systems use to calculate data size, rather than deliberate shortchanging. In some cases, pre-installed software also claims a portion of a device's total storage before a user ever touches it.
