Windows 10: hard disk capacity shows wrong size

Hi,I've a problem with updating Windows 10 Pro, since it claims that my HDD is full, but actually it is not.Basically different built-in HDD tools show different information please see below.The storage manager itself shows contradicting information, it is file sizes seem to not sum up correctly.What is the reason and how can I solve the problem?I appreciate any help -thanks!

Disk Management Shrink Volume wrong capacity

I have 6 partitions on my hard drive. Under Disk Management, when I select a partition and then "Shrink" all but one shows the total capacity correctly, along with the amount to shrink and then the remaining that will be left. However on one partition, when selecting shrink, the total capacity is the sum of the total plus the free, and not just the total capacity. As such, I cannot shrink this volume without an error. The capacity is about 350GB with the free about 200GB. When I select shrink, the total of the volume shows 550GB instead of 350GB. The correct capacity of 350GB shows correctly on the Disk Management listing and boxes on the initial screen and also under Properties on the File Manager. It is only when selecting the shrink option that it shows 550GB.

 

Partition size and total disk space don't match

Even though the partition size for Disk 0 is 953.87 GB, the total capacity shows up as 793 GB in the list of properties. There isn't any unallocated space, and Drive E (Disk 1's second partition) has a capacity equal to the partition's size. How would I
make the shown capacity equal to the partition size?

 

Hard disk partition not showing up.

Hi Muhammad,



Thank you for writing to Microsoft Community Forums.



This can happen if the Hard-disk drivers are not up-to date. I would suggest you to update the hard disk drivers first. To update the drivers, please follow the steps mentioned below:

1. Open Device manager.
   
2. Then Expand “Disk drives”.
   
3. Then Right click on the Hard-disk listed under this category.
   
4. Then click on Update drivers.
   
5. Alternatively you can also try to update the drivers from manufacturer’s website.
   

Once the hard-disk drivers are updated, you will need to allocate the last partition (it is not allocated according to the screenshot) and you will be able to view the partition.



Also note that sometimes the hard disk partitions/drives might be hidden in This PC or My Computer window due to a Registry key. If a DWORD with the name NoViewOnDrive or NoDrives is present under following key in Registry Editor:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer

Delete the DWORD and your drives will become visible in My Computer window.



Hope this helps.
