  The mixings of $d_R$ quarks, hidden from view in Standard Model (SM), are
naturally the largest if one has an Abelian flavor symmetry. With supersymmetry
(SUSY) their effects can surface via $\tilde d_R$ squark loops. Squark and
gluino masses are at TeV scale, but they can still induce effects comparable to
SM in $B_d$ (or $B_s$) mixings, while $D^0$ mixing could be close to recent
hints from data. In general, CP phases would be different from SM, as may be
indicated by recent B Factory data. Presence of non-standard soft SUSY
breakings with large $\tan\beta$ could enhance $b\to d\gamma$ (or $s\gamma$)
transitions.
