I have a Seagate Expansion 5TB USB 3.0 3.5" Desktop External Hard Drive (STEB5000100).


I attempted to create a disk image using Macrium Reflect version 6.1 Free Edition for 64-bit.


On Starting Image, Macrium failed to create the Volume Snapshot, giving error code 0x8004231f.


I had followed the instructions at


Creating a backup image of your computer, drive or partitions,


accessible via both the Macrium Reflect KnowledgeBase and the Macrium Reflect v6 User's Guide.


I was careful to not set the destination drive as also a source location.


Unfortunately, Macrium support and its forums are not available to those using the free version of Macrium Reflect.


In the Macrium Reflect knowledgebase, 0x8004231f - Failed to Create Volume Snapshot



Solution 1 - Remove drive letters allocated unnecessarily to small partitions


Solution 2 - Increase shadow storage space


Solution 3 - Remove old VSS snapshots


Device Manager says:


Lenovo_recovery (Q:) 10000 MB
Windows7_OS (C:) 465738 MB


There's 86,311,084,032 bytes of free space, BTW.


Macrium Reflect says:


MBR Disk [4A9C44DF] - ST3500418A5 CC66 <465.76 GB>


1 - SYSTEM+DRV (None)
NTFS Active
636.7 MB
1.17 GB


2 - - Windows7_OS (C:)
NTFS Primary
374.41 GB
454.82 GB


3 - Lenovo_Recovery (Q:)
NTFS Primary
9.76 GB
9.77 GB


So I guess Solution 1 doesn't pertain.


The Knowledgebase goes on to say:


Solution 2 - Increase shadow storage space


To see the amount of storage space allocated and used for Volume Shadow Copies run the following command from a command prompt with elevated privileges:


Vssadmin list shadowstorage


To allocate more storage (e.g. 50GB) run the following command:

vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=50GB


Running either one of these commands at an elevated command prompt gives the following response:


This program is blocked by group policy. For more information, contact your system administrator.


So I looked around and found this:


How to Disable/Enable Group Policy

Therein it tells you how to Disable/Enable Group Policy from the Command Prompt:


To Disable Group Policy:

REG add "HKCU\Software\Policies\Microsoft\MMC\{8FC0B734-A0E1-11D1-A7D3-0000F87571E3}" /v Restrict_Run /t REG_DWORD /d 1 /f


To Enable Group Policy:

REG add "HKCU\Software\Policies\Microsoft\MMC\{8FC0B734-A0E1-11D1-A7D3-0000F87571E3}" /v Restrict_Run /t REG_DWORD /d 0 /f


Entering the Disable command gives:


ERROR: Invalid key name.
Type "REG ADD /?" for usage.


Doing that yields:


REG ADD KeyName [/v ValueName | /ve] [/t Type] [/s Separator] [/d Data] [/f]


  KeyName  [\\Machine\]FullKey

           Machine  Name of remote machine - omitting defaults to the

                    current machine. Only HKLM and HKU are available on remote


           FullKey  ROOTKEY\SubKey

           ROOTKEY  [ HKLM | HKCU | HKCR | HKU | HKCC ]

           SubKey   The full name of a registry key under the selected ROOTKEY.


  /v       The value name, under the selected Key, to add.


  /ve      adds an empty value name (Default) for the key.


  /t       RegKey data types

           [ REG_SZ    | REG_MULTI_SZ | REG_EXPAND_SZ |

             REG_DWORD | REG_QWORD    | REG_BINARY    | REG_NONE ]

           If omitted, REG_SZ is assumed.


  /s       Specify one character that you use as the separator in your data

           string for REG_MULTI_SZ. If omitted, use "\0" as the separator.


  /d       The data to assign to the registry ValueName being added.


  /f       Force overwriting the existing registry entry without prompt.


Since "HKCU" is a valid ROOTKEY, I guess that




isn't a valid SubKey.




Then I tried Macrium Reflect > Other Tasks -> Fix VSS Problems.


It ran, but it didn't fix the problem.


So then I tried Tweaking.com's Repair_Windows.


But it's telling me to power off and unplug the computer and then remove its battery.


But I don't know what the battery of my Lenovo ThinkCentre M75e 5042 A7U looks like.


I did a Google image search, but I just got a lot of different images, and I can't match anything in my computer to any of these images.


Any suggestions?
