The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy20.

    Question

  • How would I find out which drive is the problematic disk?

      - 2 x 1 TB drives (C:\ Mirrored). - Ran chkdsk /r went on well.

      - 1 x 1 TB drive (E:\) - Ran chkdsk /r went on well

      - One external drive USB which gets rotated every day for backup. Have ran chkdsk went on well.

     

    My question is how would I map which drive is the problematic or it is complaining.

  • Hi,

     

    Based on my research, there are two main reasons to bring about your issue:

     

    I suspect that the HarddiskVolumeShadowCopy may be collapsed.

    It is suggested that you delete HarddiskVolumeShadowCopy20, you can use the command line as bellows :

    Vssadmin delete shadows /shadow=ShadowId

     

    And then , recreate HarddiskVolumeShadowCopy use the command line as bellows :

    Vssadmin create shadow /for={volume}

     

    Secondly , your disks may be collapsed, please following the steps as bellows to troubleshoot your disk:

     

    • The disk might have bad sectors.
    • I/O requests issued by the file system to the disk subsystem might not have been completed successfully.

    You can follow this link to verify the disk:

  • When does this error occur? When backing up a client? When backing up your server? What version of Windows Home Server are you using?

  • I had this issue rather consistently and found that it was due to a corrupt swap file. I deleted the swap file and moved it to another partition and the problem went away.
