Step 2: Right-click on the disk where the partition disappears and directly choose the Partition Recovery option.
Step 3: Select the scan range from Full Disk, Unallocated Space, and Specified Range, and click the Next button.
- Full Disk: It is recommended when the user does not know where the lost partition is located.
- Unallocated Space: It is recommended to use if the user did not create any new partition after the partition was lost.

Way 2: Check Hard Drive for Errors
As mentioned above, the “partition disappeared after shrink” error can be caused by hard drive errors. So, it’s important to check if the hard drive gets faulty. There are 2 methods to check the hard drive for errors. For that:
Method 1: Use CHKDSK
CHKDSK is a disk error checking and repair utility built into Windows. It scans hard drive partitions for internal errors and repairs them at the same time. To use CHKDSK to repair a corrupted hard drive partition, follow these steps:
Step 1: Type cmd in the Search box. Then right-click on Command Prompt and select the Run as administrator option to open Command Prompt as administrator. Then click Yes to get Admin access.
Step 2: In the Command Prompt window, type the chkdsk G: /f command and press Enter.
“G” represents the hard drive partition letter.
Method 2: Use MiniTool Partition Wizard
Although CHKDSK can be used to check the hard drive for errors, this tool often runs into various issues like CHKDSK being write-protected, CHKDSK getting stuck, etc. So, it’s highly recommended you use a powerful disk manager - MiniTool Partition Wizard. It can help you check bad sectors but also file system errors easily and quickly.
Step 1: Launch the MiniTool software to get its main interface, and then select the target drive and click on Check File System from the left action panel.

Step 4: Click on the Start Now button in the pop-up window. After that, this tool will scan the whole external drive immediately and show you the test result.
Step 5: When the hard drive error test process is completed, the bad sectors on the hard drive will be marked with red color. In this case, you can either use this bad sector repair guide or consider replacing it with a new one.
Once you checked the hard drive, you can see if the “hard drive space disappeared after shrink” issue gets fixed.
Way 3: Perform SFC and DISM Scan
Sometimes, corrupted or missing system files can cause hard disk partitions or volumes to disappear. To detect and repair damaged or missing system files, Windows provides two utilities. The first tool is SFC (System File Checker), which can detect and restore missing components. Another is the DISM (Deployment Image Servicing and Management) tool, which can fix more complex system errors.
To run an SFC and DISM scan on your system, you can follow the steps below:
Step 1: Open the Command Prompt as administrator.
Step 2: In the Command Prompt window, type the sfc /scannow command and press b.
Note: If the SFC scan detects any issues with system files, it may ask for the Windows installation DVD or media to repair corrupt and damaged system files. When repairing damaged files, some files saved on your computer may be deleted. So, please make sure you back up all important data.
Step 3: After its done, type the following command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
In case your computer can’t complete the SFC scan, you can read this guide to fix this problem.
