I have a Dell Inspiron laptop, which has a 500GB hard drive. It’s going so perfect
until the 500GB hard drive shows only 130GB of space suddenly in My Computer. I just
reinstalled the Windows due to problems encountering in the Internet Explorer. After
I reinstalled, the hard drive space is missing to 130GB. Why the hard drive showing
wrong capacity when it has more space in fact? How to solve the hard drive not
showing full capacity problem?
Small Knowledge: Hard Disk Storage Capacity Calculation
Typically, the hard drive manufacturer regards 1GB=1000MB, 1MB=1000KB, and
1KB=1000Byte as the standard. But in fact, 1GB=1024MB, 1MB=1024KB, 1KB=1024B. We
take 500GB hard drive for example, a 500GB (500*1000*1000*1000B) hard drive only has
the capacity of 500,000,000,000/1024/1024/1024≈465GB actually. As the same time, 1TB
hard disk will be only 931GB. Thus, we get the capacity of the hard disk usually
less than actual.
Causes of 500GB HDD Only Shows 130GB
Except for the fact that we can’t change, there are some causes result in 500GB hard
drive shows only 130GB of Space:
There is some unallocated space on that disk.
The 500GB hard disk is not authorized by official channels.
Format the 500GB hard drive with an improperly format tool.
Clone smaller hard drive to 500GB hard disk.
To fix 500GB hard drive shows only 130GB of space, please buy a 500GB hard disk from
the formal channel. And it’s worth to mention that the best way to repair the
problem is to extend the 130GB partition without losing data.
