Storage Spaces: 1 of 4 HDs failed, can’t access/repair pool
I have a Storage Spaces pool with four 4Tb external USB drives, set up with two-way mirroring. One of the drives started making a loud buzzing noise and interfering with other USB devices. I shut down the system and disconnected the drive (the system will not function correctly and the storage space drive is inaccessible with the bad drive connected). When I restarted, the storage space was inaccessible. Running the Storage Spaces Manager, the only option available is to delete the pool (clicking the “Change settings” button does nothing):
I initially assumed that I couldn’t repair the pool because there wasn’t enough free space on the remaining three drives, so I added a new 8Tb external USB drive. Storage Space manager can see the new drive and will let me create a new pool using it, but won’t allow me to add it to the existing pool. As already mentioned, the only option that I have is to delete the existing pool.
The computer is running Windows 10 Home, version 1803, build 17134.1069. It looks like the last update was 2019-10 Cummulative Update … KB4520008 on 10/9/2018. Version 1903 feature update failed to install 8/29/2019 – 0x80240034.
I do not believe that the drive failure was related to update activity. CrystalDiskInfo 7.5.0 was showing the drive as good, with no warnings, prior to the failure.
Assorted drive information:Any assistance would be greatly appreciated.Code:Windows PowerShell Copyright (C) Microsoft Corporation. All rights reserved.
