Magneto-drag reveals the nature of compressible states and the underlyinginterplay of disorder and interactions. At \nu=3/2 a clear T^{4/3} dependenceis observed, which signifies the metallic nature of the N=0 Landau level. Incontrast, drag in higher Landau levels reveals an additional contribution,which anomalously grows with decreasing T before turning to zero following athermal activation law. The anomalous drag is discussed in terms ofelectron-hole asymmetry arising from disorder and localization, and thecrossover to normal drag at high fields as due to screening of disorder.Comment: 5 pages, 4 figure
