WinXP x64 Cloning tools
 

anyone know of a cloning tool for windowsXP X64?

Nope, sorry. However you could maybe set up a dual boot situation and use the 32-bit tools in 32-bit winXP? Thats what I do, I use my 32-bit windows XP as a fallback for any apps which don't work in x64. The nice thing here is that DT4 DOES have x64 compatability, so I can work with images in XP32 and use them in x64.
