So my mother got herself a new laptop, and laptop has 2tb hard drive inside, but there is only one disk - C, and i want to create a partition called disk D, leaving 400gb for that disk C and the rest for disk D, but does it affect windows, it wont be like - some of windows files are in that area where is disk D space and windows cant get them because its in different partition? i didnt tried creating partition in windows, i always was doing it on windows install when you select in which disk to install windows and you create a new partition...
