How to Fix: Storage Spaces Critical Write Error
Storage Spaces Critical Write Error fix for Hyper-V VHDs on Windows 10
📋 Table of Contents
A Storage Spaces critical write error occurs when the storage space is unable to write data to its disks, causing the entire storage space to become offline. This issue affects users with Windows 10 boxes configured using Storage Spaces, particularly those running Hyper-V virtual machines (VMs) on top of it.
This problem can be frustrating as it prevents VMs from starting and accessing their VHDX files, leading to downtime and potential data loss. In this troubleshooting guide, we will explore the possible causes and provide two methods for resolving the Storage Spaces critical write error.
🛑 Root Causes of the Error
- The primary cause of a Storage Spaces critical write error is related to the Hyper-V VHDs being written on top of it. When Windows updates are applied, they can sometimes conflict with the way Hyper-V handles VHDX files, causing issues with data writing and leading to the storage space becoming offline.
- Another possible reason for this issue could be a misconfiguration or compatibility problem between Storage Spaces and the new Windows 10 build (1709). This could potentially cause problems with the storage space's ability to write data, especially when using Hyper-V VMs.
✅ Best Solutions to Fix It
Reconfigure Hyper-V VHDs on a separate disk
- Step 1: Pull the VHDX files from the Storage Spaces virtual disk and copy them to a different disk (such as an SSD or another disk with enough free space). This will temporarily remove the issue and allow you to test if the VMs run without problems.
- Step 2: Create a new virtual disk on the separate disk using Hyper-V Manager. Import the VHDX files from the original disk into this new virtual disk. Verify that the VMs start successfully and can access their files without any issues.
- Step 3: If the issue persists, it may be necessary to reconfigure the Storage Spaces setup or update the Windows 10 build to a version that is compatible with Hyper-V VHDs.
Update Windows 10 and Storage Spaces
- Step 1: Check for any available updates for Windows 10 and install them. This may include updates related to Hyper-V or Storage Spaces.
- Step 2: After updating Windows 10, run the WD Diagnostic tool with extended tests to ensure that all disks are functioning correctly and there are no issues with data writing.
- Step 3: Verify that the Storage Spaces setup is configured correctly and that the virtual disk is properly set up for use with Hyper-V VMs. If necessary, consult the documentation or seek support from Microsoft or Western Digital for further assistance.
🎯 Final Words
To resolve a Storage Spaces critical write error caused by Hyper-V VHDs on top of it, try reconfiguring the Hyper-V VHDs on a separate disk (Method 1) or update Windows 10 and Storage Spaces (Method 2). If the issue persists, consider seeking further assistance from Microsoft or Western Digital. By following these steps, you should be able to identify and resolve the cause of the critical write error and get your storage space up and running again.
