I had a similar problem.
the model that failed is: WD5000AAJS-32YFA0
the donor is: WD5000AAJS-22TKA0
it is impossible to find the same harddrive anywhere

the resource master creation in DB did work 100%
then i restarted the tool in kernel mode and go to:
Tests->Work with ROM -> ROM recovery
the wizards starts.
then i choose the right model resource i imported from Tornado2R.pcr.
then ic click the button ">>"
then i get a popup stating "Fatal error" and the wizard is closing.
no matter which version i choose from the list it always dies with "Fatal error".
any hints?
