Thank you sir.  A most valuable contribution.  

Got mine all done.  Tool worked well.  I think my post tool read speeds are slightly lower but whatever.

Yes.  I used the tool myself several weeks ago.

Isn't this thing supposed to find all your HDs? It only finds my C which I do not want to clone . I have my FSX on a seperate drive but it doesn't even show up on the migration tool.
