Can the memory of hard disk reduce? My hard disk capacity is 500 GB . It is showing 400 GB in windows and 20 GB in ubuntu . Is the remaining memory

The Hard Disk capacity may be 500GB, but it appears you have set up a 400GB Windows partition and a 20GB Ubuntu partition.

The remaining 80GB, it seems, has not been allocated.

The remaining is not lost, you could either set this aside a new drive, or even extend the volumes currently in place?

Can we get a screenshot of your disk management ?

Where did you see the current capacity?

There is a good 3rd party tool called treesize from Jam software tht will tell you what is using the space

Hello prudhvi,

Based on the screenshot, the capacity is seemed right.

About the hard drive actually capacity, it is recommended to contact the manufacturer.

Thanks for your understanding.
