Missing Unallocated Space After the Volume Shrink, How to Resolve?

I used the disk management tool to reduce the SSD size where Windows 10 is installed. I entered something like 70GB and hit the shrink button, but instead of the free space showing up so I could make a new partition, it simply vanished.

To solve this problem properly, you need to know the causes. Thus, I rounded up the main reasons below for your information:

  • File system error or system files lost
  • Corrupted drive
  • Malware and virus attack
  • Outdated hard drive driver

Many methods can apply to this case, including running a system file checker, using the CHKDSK command, and launching third-party partition resizing software. However, the CHKDSK command has many types of checking different hard drive errors. You can go through this article to learn how to utilize these commands as follows:
