Windows 10: Storage size of C Drive not matching actual storage space

I extended my C Drive from 235 GB to ~476 GB using Disk Management; however, most things are still showing 235 GB and I am still limited by that smaller size storage space. The SSD inside should be a 512. I am using a new Lenovo ThinkBookI have run Disk Optimization, a BIOS SSD check, disk cleanup utility, checked for windows updates, chkdsk via Admin command prompt. I went into device manager and searched for drivers for each of the storage controllers. I attempted to shrink the partition back and got error 0x80070057. Here is some system info:Here are a couple of the commands I have run:&n

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!

 

Storage Spaces not showing increased size..

Hello, Size was increased via storage spaces. I was able to fix the issue. It seems like size increase via storange spaces is not working. I manually have to reboot and then use following command to show the correct size.

C:\ > DISKPART

DISKPART> List Volume

DISKPART> select volume # (this is the number of the volume listed by the above ‘List Volume’ command)

DISKPART> extend filesystem

DISKPART> exit

This fixes the storage pool to show the correct size. But its really annoying to do that every time you increase the size of the pool.

Thanks

 

Storage showing as double the actual SSD size

Running Windows 10 Home 20H2 (Build 19042.964) on an AMD based Windows Surface Laptop 4 with 512GB SSD.

Even though it has a 512GB SDD as confirmed by both disk management and file explorer, settings -> system -> Storage reports the size as 951GB! I have searched but struggling to discover how to get it to report the real size.

Per the image below it shows

• 553GB used - bigger than the size of the SDD
  519GB in system & reserved

System and reserved breaks down per this screenshot




Have tried various options including disk cleanup, SFC and DSIM to get it to report the correct size but to no avail. Any suggestions on how to correct this much appreciated?
