When you tried you didn't did your best I think, cause I managed how to edit the registry with the hard drive on slave.
It's good to believe what you have experienced, I do that too, but sometimes you have to take risks!
I'll post sort of guide which I wrote and it worked successfully.
A guide to edit the registry of a slaved Hard Drive on a XP System.
NOTE 1 : to edit the system hive the regedit will ask you for the key name; search it from the
URL : http://msdn.microsoft.com/en-us/library/ms724877(VS.85).aspx
NOTE 2 : The table that shows the Registry Hive and the supporting Files is described in the
Registry Hive : The Hive you want to edit
Supporting Files : Is the Key Name that regedit will ask for the hive you wish to edit.
Start > run > type regedit > click on machine
File > Load Hive
Browse to the slaved Hard Drive; Windows > System 32 > Config > choose the hive you want to edit and
search the key name from the above site.
You have full control of the registry of the Hard drive that is slaved connected.
DO IT AT YOUR OWN RISKS!
I like to write how I solved my own and others problems, the above is one of them.
