Scenario: Hard drive not showing full capacity

 

I have a Dell Inspiron laptop, which has a 500 GB hard drive. It’s going so perfect until the 500 GB hard drive shows only 130 GB of space suddenly in My Computer. I just reinstalled Windows 11 due to problems encountering in Internet Explorer. After I reinstalled it, the hard drive space is missing to 130 GB. Why the hard drive showing the wrong capacity when it has more space in fact? How to solve the hard drive not showing full capacity?

 

What you should know about hard disk storage capacity calculation

Typically, the hard drive manufacturer regards 1 GB=1000MB, 1 MB=1000KB, and 1 KB=1000Byte as the standard. But in fact, 1 GB=1024MB, 1 MB=1024KB, 1 KB=1024B. We take 500 GB hard drive for example, a 500 GB (500*1000*1000*1000B) hard drive only has the capacity of 500,000,000,000/1024/1024/1024≈465 GB actually. As the same time, 1 TB hard disk will be only 931 GB. Thus, we get the capacity of the hard disk usually less than actual.

What causes 500 GB HDD only shows 130 GB?

Except for the fact that we can’t change, there are some causes that result in 500 GB hard drive shows only 130 GB of Space:

▪ There is some unallocated space on that disk.
▪ The 500 GB hard disk is not authorized by official channels.
▪ Format the 500 GB hard drive with an improper format tool.
▪ Clone smaller hard drive to 500 GB hard disk.
▪ Virus attack.

To fix 500 GB hard drive that shows only 130 GB of space, please buy a 500 GB hard disk from the formal channel. And it’s worth mentioning that the best way to repair the problem is to extend the 130 GB partition without losing data.
