WHS backup fails on one computer with event codes 773 followed by 770 RRS feed

  • Question

  • WHS started warning me that one of my computers had not been backed up for a number of days. Tried to do a manual backup and get the following two exceptions in the event log. The WHS failure message directed me to the event log for "more information"

    Event 773: Home Server

    Backup of volume C: to CUBE failed: System.Runtime.InteropServices.COMException (0x8007045D): The request could not be performed because of an I/O device error. (Exception from HRESULT: 0x8007045D)

    Event 770

    Looking around, I saw some recommendations about removinf conflicting products of which I had none. I also checks Processor utilization on my server and it was low at <15% during one of the failed runs.

    The System event log reports another worrisome error occurring at around the same time: 

    Event 11, atapi

    The driver detected a controller error on \Device\Ide\IdePort0.

    Some weeks ago I did run a CHKSDK of the rive (had to do a reboot to allow it to run) but as far as I saw, no errors were reported.

    Any other suggestions/advice?  This is a laptop, so the drive plugs into the motherboard on the SATA adapter, there is no cable to check.
