A study was carried out to determine how the metastable disordered phase (DP) modifies the apparent transport behavior. For this purpose, transport studies in a Corbino disk geometry were carried out. A comparison was also made with the regular strip configuration in the same crystals. It was observed that the two geometries yield a strikingly different response and, significantly, the instability effects are eliminated in the Corbino geometry. By preventing the edge contamination, the true bulk dynamics in the vicinity of the transition was probed.
