Backup error code 0x80070490 RRS feed

  • Question

  • Hello please help.  I am getting the error code 0x80070490 every time I try to backup to an external HD.  I cant go back and do a reset, it's been happening for a very long time.  I have tried the resolution that Olaf advised the chkdsk /r.  It didn't work.  

    The Microsoft technical folks tell me that it is a missing registry key  in HKEY_Local_Machine/System\CurrentControlSet\Control\StorageDevicePolicies  but I really hesitate to try to look in the registry alone.  Thanks and Help!
