There is a problem with the hard disk capacity calculation method !!

I encountered this problem in 98 years! Windows 95 adopts the 1024 calculation method, while university textbooks are also the 1024 calculation method! When I bought a computer in 98 years, I found that the hard disk capacity was not the same as the system's statistical capacity! Only then do you know that the hard drive vendor uses the 1000 calculation method! At the beginning, I didn't want to reduce the capacity!

Now I have changed my computer and 80 GB hard drive. WIN2K is a 76G hard drive .... I am 4 GB missing! I know why.

Do you care about this 4G? An 80 GB hard drive is about 5% less than 4 GB. I can only buy 2 GB hard drive at 800 RMB in 98 years. I have 8 GB hard drive capacity on the front-end computer. Install WIN2K vc bc delphi SQL SERVER 2 K ORACLE9I image on an 8G hard drive, squeeze out space as much as possible, delete some ebook and materials, and convert MP3 into a 1 m WMA. That kind of stingy taste is so uncomfortable !!

Now 80G 100G 120G 150G 160G 200G 320G large capacity hard drive is coming out, you can calculate the capacity will be less!

We found that the vendor uses the 1000 hexadecimal format starting from Kb.

100G = 100*1000 (M) * 1000 (K) = 100,000,000 KB/1024/1024 = 95.367G less than 5G

200G = 190.7G less than 10G

300G = 286.1G, 14G less

Two years later

500G = 476.8G less than 24G

1000G = 953.6G less than 47G

Although the hard disk is divided into many areas when the machine is installed, users cannot easily detect it at the moment. when many computer users still do not pay attention to the capacity. even if you can convince the customer of the different computing capacity methods of the operating system! Can customers accept this big difference? In this age of deception.
