Windows 10: Windows 10 File History does not recognize some of the partitions.

If you are having trouble getting Windows to recognize all of the partitions on your PC, you are not alone. I read many suggestions from other users, none of which worked. My PC has a lot of disks, many with multiple partitions and some with only one partition. The partitions that would be displayed in the File History Select Drive option were all partitions on drives with a single partition. None of the partitions that existed on drives with other partitions are displayed in the list of drives that you should be able to select.How to beat it...Reassign the partition letter that you want

HDD partitions format

Used a tool from the list and it worked..
Install won't start if windows can't recognize the partitions.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

File History Physical Connected But Not Electronic

Hello Candun,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that File History is not recognizing the external USB expansion drive, even though the drive had worked initially and it was behaving normally in File Explorer.

This issue may occur if any of the backup in the drive you are backing up is corrupted or the library is corrupted.

Please follow the below suggested methods and check if it helps to resolve the issue.

Method 1

1. Open File History and click Select Drive. Select a different drive other than the one that is failing to be recognized. you can consider adding an extra internal HDD to your PC in this situation.

2. Go to the external USB drive that wasn't being recognised, find the File History folder and rename it to "File History.old" or delete it.

3. Go to your C:\Users\your user folder\AppData\Local\Microsoft\Windows, find the File History folder and rename it "File History.old" or delete it.

4. Re-open File History, click Select drive and select the original USB drive that was not being recognised. The drive should now set up normally and start operating.

5. Delete the File History folder on the drive used in step 1

Method 2

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
  
• 
  In Command prompt type
  sfc/scannow and press enter.
  

• Restart the computer.

If no corrupted system files were found in the previous state, then I suggest you to try the following steps to employ the DISM command lines:

• 
  Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
  
• 
  In command prompt, type the following commands and press Enter after each command:
  

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

• 
  Close the command prompt and restart the PC and check if it works.
