Backups Failing on Win7 64-bit Client RRS feed

  • Question

  • For some reason, my backups recently started failing on my Win7 Home Premium 64-bit notebook. This is to a home built WHS (v.1). Until last week I never had any issues. The backup gets to about 10% (indicating that is checking for clusters that need backing up). Then I get a message that the backup has failed due to a problem with the WHS connector software and that there is more info in the system event log. That info is:

    System.Runtime.InteropServices.COMException (0x80070001): Incorrect function. (Exception from HRESULT: 0x80070001) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at Microsoft.HomeServer.Common.Client.Win32.ThrowLastError() at Microsoft.HomeServer.Backup.NTFS.VolumeBuffer.EndRead() at Microsoft.HomeServer.Backup.NTFS.ClusterBitMapReader.Dispose() at Microsoft.HomeServer.Backup.BackupOp.BackupOperation.DoClusterPass1() at Microsoft.HomeServer.Backup.BackupOp.BackupOperation.RunWithoutCatch() at Microsoft.HomeServer.Backup.BackupOp.BackupOperation.Run()

    I have tried uninstalling and reinstalling the connector, I have done a chkdsk on the notebook, and it found no errors. I have tried the steps suggested in this FAQ about fixing the Volume Shadow Copy system.

    I have also tried the backup with both wired and wireless network.

    Nothing seems to work.

    Any help would be greatly appreciated.

  • FYI, I was able to fix this problem by running chkdsk again using the "Scan for and attempt recovery of bad sectors" option (which takes quite a while to run on a 500gb hard drive). It found bad sectors in one file, and repaired them. The next backup completed normally.
