Hello, so I have a 240gb Profession SSD, but in my files it says it only has 222gb and can only hold that much, does anybody know how to fix this?
240GigaBytes is marketing speak for 222GibiBytes. The SSD/HDD vendors sell things in Gigabytes which is 10^9 bytes. However, your OS sees things in Gibibytes which is 2^30 bytes.
