Second, the test

1. Computer hard Drive information

2. Hard drive information in My Computer

3. Test code

4. Output Result:

All hard disk and USB stick and memory card, because the manufacturer's calculation method and operating system calculation method is not the same, the former according to 1MB = 1000KB calculation, the latter by 1MB = 1024KB calculation, so, the actual capacity in the computer can be seen with the factory brand name capacity has a certain difference, the law is 1G = 0.9 3G (approximately equals), such as 100G, the actual 100G * 0.93 = 93G, the specific capacity can be referred to this formula calculation.
