Measurement of the free flux flow resistance in monocrystalline highly anisotropic BSCCO reveals a low field magneto-resistive effect nearly 100 times that expected from a naive application of the Bardeen-Stephen rule R/Rn = B/Bc2. Furthermore in the vortex solid phase it saturates to a constant value at about Hc2/100 as if the vortices were moving 100 times faster than expected. An attempt to account for this behavior by a combination of sheared planar vortex flow obeying the BS rule and the quasi-particle c axis conductivity between the Josephson coupled superconducting planes is only partially successful. In particular it is unable to account for the saturation feature which occurs in both optimally and underdoped samples in the low temperature vortex solid phase.
