Thanks Shawn I did try a copy with Partition Wizard after successfully diskpart - format of the external drive.
But as you can see the partitions are not quite as I expected to see them - I thought it would be a clone like image. The main partitions E & K open to reveal the same info on but the "end" partitions do not.
Having said that Partition Wizard lets me do that and the same info is in both.
Now my only concern is that the Vista will be lost if I clean all that old drive for a trial of Windows 8, and that I would not be able to put it back on to that drive.
I would like to keep that copy of Vista for reference when I have a Vista fix in, personally I think it is such a cumbersome program but I do have friends who actually like it??
