Storagecraft: Resolving Inaccessible Boot Device After Upgrade Shadow Protect to 6.7.x
Here's what appears to be working for us.
Method 2 - Patch the driver within the Recovery Environment:
Download the patched driver, which is version 2.2.73.0.36. After the patched driver has been received from support then:
- Download the patched driver: MSFT_Signed_stcvsm-2.2.73.0.36.zip
- Boot to the StorageCraft® Recovery Environment (either the Windows or Crossplatform version will work). Alternatively, if the volume is a VHD/VHDX, it can be mounted and explored through Hyper-V.
- Identify the OS volume within the Recovery Environment (it might not default to C:).
- Copy the 2.2.73 driver to %windir%\system32\drivers on the OS volume. Be sure to select the correct version for the operating system in question, either x64 or x86.
- Reboot the machine.
- If the issue persists, move to the next method.
Method 3 - Edit the registry to remove the driver:
- Boot to the Recovery Environment for Windows.
- Open Tools > Command Prompt
- Type the following command, substituting the correct letter for the system volume as it may be different in the Recovery Environment, and press Enter:
reg load HKLM\SYSTEM_PROD C:\Windows\System32\Config\SYSTEM
- Type in regedit and press Enter.
- In the registry, navigate to:
HKLM\SYSTEM_PROD\ControlSet001\Control\Class
- Search for stcvsm until you find the key for UpperFilter that contains the string stcvsm.
- Edit the key and ONLY remove stcvsm, retaining the rest of the text.
- Repeat steps 5 through 7 under ControlSet002.
- Close the Registry Editor.
- Run the following in the command prompt:
reg unload HKLM\SYSTEM_PROD
- Exit and reboot.
