Ghost 15 Copy Drive - Failed

I'm running windows 7 and I am trying to copy my main drive (500GB of 1TB) to an external USB 2.0 Hitachi 1TB).  I want to replace the existing drive with the Hitachi.

 

I check off:

Source drive to copy: HP (C:\)

Destination:
    New Volume (J:\)

Options:
    [X] Check source for file system errors
    [X] Check destination for file system errors
    [  ] Resize drive to fill unallocated space
    [X] Set drive active
    [X] Disable SmartSector copying
    [X] Ignore bad sectors during copy
    Destination partition type: Primary
    New drive letter: J:

Advanced options:
    [X] Copy MBR

 

and get:

 

-Error EC8F17B3: Cannot complete copying of HP (C:\) drive.
--Cannot copy source drive to destination location.
---Error E7C3000F: Device \\?\SymantecSnapshot1 cannot read 20480 sectors starting at LBA 6205440.
