Windows 10: No D Drive showing when upgrade from Windows 10 to 11.

I tried using Disk management but did not see anything related to my D Drive or unallocated space. Initially after the upgrade to 11 my D drive was assigned to my DVD drive. I changed it to E drive. Rebooted and still same issue. I also used CMD and list disk and that did not show a D partition.I am not technical so any help would be greatly appreciated. I

D drive is showing, but access denied.

Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

To resolve the "access denied" issue on your D: drive in Windows 11, follow these comprehensive steps to diagnose and fix the problem. These steps include taking ownership, running CHKDSK, and modifying the registry.

Step 1: Take Ownership of the Drive

1. Open Command Prompt as Administrator:
   
   • Press Windows + X and select "Windows Terminal (Admin)" or "Command Prompt (Admin)".
     
2. Take Ownership:
   
   • Type the following command and press Enter:
     
     
   • This command will recursively take ownership of the D: drive, granting your user account the necessary permissions.
     

Step 2: Run CHKDSK

1. Open Command Prompt as Administrator:
   
   • As in Step 1, open the Command Prompt with administrative privileges.
     
2. Run CHKDSK:
   
   • Execute the following command:
     
     
   • Explanation of parameters:
     
     • /f: Fixes errors on the disk.
       
     • /r: Locates bad sectors and recovers readable information.
       
     • /x: Forces the volume to dismount first if necessary.
       

Step 3: Modify the Registry to Display the Security Tab

1. Open Registry Editor:
   
   • Press Windows + R, type regedit, and press Enter.
     
2. Navigate to the Explorer Key:
   
   • Go to:
     
     
3. Check or Create NoSecurityTab:
   
   • Look for a DWORD entry named NoSecurityTab.
     
   • If it exists and is set to 1, right-click on it, select "Modify", and change the value to 0.
     
   • If it does not exist, create it:
     
     • Right-click on the Explorer key, select New > DWORD (32-bit) Value, name it NoSecurityTab, and set its value to 0.
       

Step 4: Check Disk Management

1. Open Disk Management:
   
   • Press Windows + X and select "Disk Management".
     
2. Check the D: Drive Status:
   
   • Locate the D: drive and check its status.
     
   • Look for any errors or unusual statuses (like RAW). If the drive shows as RAW, it may need to be formatted, but only consider this as a last resort due to data loss risks.
     

Additional Tips

• Update Windows 11:
  
  • Ensure your system is up to date by going to Settings > Windows Update and checking for updates.
    
• Use Third-Party Tools:
  
  • Consider using third-party disk management tools like EaseUS Partition Master or similar to diagnose and repair disk errors.
    

Important: Backup Data

Before proceeding with any major changes or repairs, ensure you back up any important data from the D: drive if possible. Data recovery services should be considered if you suspect severe disk corruption or hardware failure.

If none of these steps resolve the issue, the problem might be more complex, potentially involving hardware failure or severe file system corruption. In such cases, professional data recovery services may be necessary.

Please do let me know if the method I suggested works for you or if you need further assistance.

 

Windows 10 upgrade rant..

The free space shouldn't prevent you from upgrading to built 1607. I manually upgraded my own laptop which had only 9gigs free space left on the system drive.

I unzipped the Windows 10 Pro anniversary edition ISO on my D drive, and started the upgrade process from there. At one point the installer complained about not having enough free space on the main drive, i just had to point it to the D drive to proceed to the next step. Now the rollback installation is stored there and doesn't clog up the C drive anymore.

In your case you could insert a large sdcard to act as the required rollback drive, i'm pretty sure it would do the trick.

Oh and by the way, if you want to further compress your System files:

• do a search Command Prompt, right-click it, and select Run as administrator.
• Type COMPACT.EXE /CompactOS:always and hit Enter.

You'll will gain anything from 2 to 4 gigs free space after it's done.

 

Upgraded from windows 8.1 to 10 now D drive missing

Hello,

Upon upgrading to Windows 10 from Windows 8.1 my D drive is no longer listed under my PC. I tried a search and cannot find it nor can I do a system restore as that requires the D Drive. Any suggestions would be appreciated.
