Why is the hard disk capacity displayed on the computer different from that marked on the hard disk?
This is caused by the different calculation methods of hard disk manufacturers:
1. Computers perform calculations in binary based on 210 = 1024. That is, 1,024 B = 1 KB, 1,024 KB = 1 MB, 1,024 MB = 1 GB, etc.
2. For the convenience of production and calculation, hard disk manufacturers all perform calculations based on 1,000 B = 1 KB, 1,000 KB = 1 MB, 1,000 MB = 1GB, etc.
3. Calculated in this way, the capacity of a hard drive with the nominal capacity of 1 TB is actually about 931 GB, which is much less than 1,024 GB (by about 93 GB).
