Lenovo computers come with preinstalled Product Recovery Program, so the hard disk has a special portion partitioned before delivery, which is used to store hard disk mirror and Product Recovery Program program files. The size of the reserved space for this partition varies according to the model, operating system and software of the computer. For the sake of safety, this partition is not evident, which is commonly referred to as a “hidden partition”.
In addition, after the hard disk is partitioned or formatted, the system will assign a certain amount of hard disk space for the system files.
For the above reasons, the available hard disk space indicated by the operating system is always less than the computer’s nominal hard disk capacity.
