Reconnecting a lost Microsoft Storage Space? RRS feed

  • Question

  • Hi,

    I recently have "lost" my storage space; unplugging the sata cable while the system was running and when reconnecting it stupidly clicking yes to create new GPT (one of the HDDs failed in the Space and I was trying to get it back).

    I've been able to recover a portion of the files using a third-party recovery tool; however the Office files haven't been recovered.

    I'm wondering, as the Storage Spaces do still exist and are still detectable both in Storage Spaces itself and through the method shown here: 

    https://www.sevenforums.com/hardware-devices/39197-virtual-hard-drives-missing-my-64-bit-windows.html#post383587

    If there's not a simple way of reassigning these drives to the system? I've tried googling this issue but haven't found anything so far...

    Thanks

  • Here are btw the results from PowerShell. The Storage Pool is spread over the two WD HDDs. As I've simply lost the parition and volume I would think it'd be as simple as setting a new volume from the virtual disk; but going over the PowerShell commands there doesn't seem to be any such one...

  • Hi,

    Thanks for your question.

    When the virtual disk is in a Warning health state, it means that one or more copies of your data are unavailable, but Storage Spaces can still read at least one copy of your data.

    We can find out what state virtual disks are in, use the following PowerShell commands:

    Get-VirtualDisk | Select-Object FriendlyName,HealthStatus, OperationalStatus, DetachedReason
    
    
    

    The virtual disk at the degraded state because of one or more drives failed or are missing, and there are outdated copies of your data on these drives.

    We can try the following steps to see if it works.

    1. Reconnect any missing drives, replace any failed drives, and if you're using Storage Spaces Direct, bring online any servers that are offline.

    2. If you're not using Storage Spaces Direct, next repair the virtual disk using the Repair-VirtualDisk cmdlet.

    Storage Spaces Direct automatically starts a repair if needed after reconnecting or replacing a drive.

    Besides, we could use the following cmdlets to monitor the physical disks’ states.

    Get-PhysicalDisk | Format-Table FriendlyName,MediaType,Size,CanPool,CannotPoolReason

    We can refer the docs to see that the drive at split status due to The drive has become separated from the pool. We can do the following action,

    Reset the drive, erasing all data from the drive and adding it back to the pool as an empty drive. To do so, open a PowerShell session as an administrator, run the Reset-PhysicalDisk cmdlet, and then run Repair-VirtualDisk.

    To get detailed diagnostic info about this drive, follow the steps in Troubleshooting using Windows Error Reporting > Physical disk failed to come online.

    Hope above information can help you.

    Highly appreciate your effort and time. If you have any question or concern, please feel free to let me know.

    Best regards,

    Michael
