We examine a system of binary disks that is known to exhibit a jamming transition at a well defined density termed point J. We add quenched disorder and measure the external force needed to depin the disks or send them into motion as a function of disk density. We find a rich variety of depinning behaviors. For small amounts of disorder, only the jammed or stiff phases are pinned. For strong disorder, disks in unjammed samples with densities well below jamming are more strongly pinned than disks in samples at densities close to the jamming transition. We also discuss connections to the peak effect for depinning in vortex systems.
