And I have decided on disk to clean disk on your good advice.
And will not persist on this topic after this final inquiry .

But -- sticking [hypothetical] wonderment Re:
as you "do" have other partitions in the original disk which is not available in the target (or recipient) disk. Thus the first sector or MBR of your two disks will be different.
My source/origin disk has NOTHING on it but the FAT32 D: utility (first)
and the ntfs C: operating main (second).

I proposed:
To first fill a clean first FAT32 partition on the recipient/target disk with the D: contents from the source/origin; as I did before.
To then fill a clean second ntfs partition on the recipient/target disk with the C: contents from the source/origin.
The target/recipient disk DOES/would have some other stuff...but only on latter partitions.

I am dependent on a live/CD Parted Magic for most of these machinations, having had good luck
with that external operator and uncomfortable as generally I am with command line operation
(absent specific, almost cut & paste guidelines), so....'nuff sed.

And ALL of that said...I am done troubling this issue and you, who I am sure have much better things to do.
I wish there were a way to donate to your nice resource but have been politely declined in that.
So --cheers anyway, then and most gratefully, yours...
