In recent papers, we have shown that analysis of observed disturbances in extended HI disks can be used to constrain the mass and current location of galactic satellites (Chakrabarti & Blitz 2009; Chakrabarti & Blitz 2011; Chakrabarti, Bigiel, Chang & Blitz 2011). This method, known as Tidal Analysis, was developed to characterize dark matter sub-structure and does not require any knowledge of the optical light from galactic satellites. Here, we explore the role of halo concentration and shape in producing these disturbances. Specifically, we investigate if disturbances in extended HI disks can be used as an observational probe of the concentration of the dark
matter halo of the primary galaxy. We also report recent results on the analysis of halo shapes on the production of disturbances in extended HI disks.
