The actual hard drive capacity of the Xiaomi Book is small
This is due to a misunderstanding caused by the difference in data units used by hard drive manufacturers and operating systems:
1. Common data measurement units are defined by two organizations: SI and IEC. SI uses a base-1000 system, while IEC uses a base-1024 system. SI (International System of Units) defines common units as KB, MB, GB, TB, etc. IEC (International Electrotechnical Commission) defines common units as KiB, MiB, GiB, TiB, etc;
2. Hard drive manufacturers use the SI base-1000 system for calculation, while computer operating systems use the base-1024 system. This discrepancy causes a difference between the nominal capacity of the hard drive and the actual displayed capacity;
3. Additionally, Windows systems can create multiple hidden partitions during installation, which are used for booting the operating system and system recovery in case of damage. These partitions are not accessible to you, which also contributes to the difference in the actual usable hard drive space displayed.
Note:
In the Windows operating system, GB (base-1000) is actually GiB (base-1024). This is because, at the time the Windows system code was written, there was no complete standardization of the base system.
Please understand that the calculation method and structure of disk space means that the space shown in 'This PC' does not represent the entire disk space. Therefore, this phenomenon is not a fault or a configuration mismatch.
Calculation of total disk space (taking a 1TB hard drive as an example):
C drive + D drive + ESP partition + MSR partition + WinRE partition = Total disk space.
195.3GB + 757.2GB + 260MB + 128MB + 1024MB ≈ 953GB
A 1TB hard drive actually has a size of approximately 953GB. The visible partition sizes C + D are approximately 952.49GB, and the hidden partitions ESP + MSR + WinRE are about 1.37GB.
As long as the discrepancy is not too large, it is not an issue.
