    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.

    Any assistance would be greatly appreciated.

    Please post a screenshot or log from Crystal Disk that shows info on the problem drive. A update is not going to cause a drive to buzz and fail, a hardware failure will. I would open the drive case, pull the drive and test in a new case. How long have you had these drives?

    Smartmontools will lwt you actually run tests on the drive. Download – smartmontools

    I agree that this has nothing to do with updates, but since that's a common Storage Space problem, I included that information. I'm sure that the drive is bad. If it's connected, it messes up any USB devices, including my keyboard and mouse. IIRC, Crystal Disk wouldn't show it or the other USB drives when the bad drive was still connected. I don't see any log file(s) in the Crystal Disk folder.

    BTW, the buzzing stopped the first time that I restarted the system, but the USB problem continued until I isolated and removed the bad drive.

    I SHOULD be able to just replace the bad drive with a new drive and get the Storage Space back on line, correct?

    I've connected the replacement drive to the system, but the Storage Spaces manager won't let me connect it to the pool or do anything else, and I don't know why. I've got data in the storage pool that isn't backed up and I'd like to get access to the pool so that I CAN back it up.

    Thanks! I'll have a look at those links on Monday.

    1st problem to be resolved if possible: readonly pool, detached virtualdisk
    2nd problem: replacing physicaldisk, recalculating data, removing failed physicaldisk object; more on it later

    Storage Spaces pool with four 4Tb external USB drives
    Suicidal choice although it can be created; if one device influences others, any damage can arise.

    Storage pool Read-only Unhealthy False False 14.55 TB 11.54 TB
    Storage space Mirror 1 Detached Unhealthy 7.25 TB 11.54 TB 62.82%
    try this:
    Code:
    Get-StoragePool "Storage pool" | Set-StoragePool -IsReadOnly $false
    Connect-VirtualDisk -FriendlyName "Storage space"
    and paste results here
    also see event log Microsoft - Windows - Storage Spaces Driver - Operational for problems, paste them here too

    If this does not work, try to extract the "failed" harddisk from USB enclosure and connect it directly to SATA interface.

    That worked! Thanks!

    The commands brought the storage spaces drive back online and I was able to update my backup. It also caused the "add drive" option to appear on the storage manager dialog. I added the new 8Tb USB drive, and then was able to remove the bad drive from the pool. The pool is now busy repairing itself.

    You said that my drive array is a "suicidal choice". What do you recommend instead?

    I'd strongly suggest that using a configuration like that you put in place continuous drive state monitoring and reporting.

    That way you hopefully get early indication of a degrading drive, and can take action before there's a catastrophic failure.

    Hard Disk Sentinel (not free) is excellent.
    Crystal Diskinfo (free) has reporting features.
