Abstract We compare some predictions of Wagoner & Tandon (WT) with the results of the hydrodynamic and magnetohydrodynamic (MHD) simulations of Reynolds & Miller (RM). It appears that the MHD simulations were not run for long enough and the numerical damping was not small enough to produce the observed high-frequency QPOs (and the g-mode seen in the hydro simulations).
