Is this correct/expected behavior? Yes. From sbp(4): Some users familiar with umass(4) might wonder why the device is not detached at the CAM layer when the device is unplugged. It is detached only if the device has not been plugged again during several bus resets. This is for preventing to detach an active file system even when the device cannot be probed correctly for some reason after a bus reset or when the device is temporary disconnected because the user changes the bus topology. If you want to force to detach the device, run ``fwcontrol -r'' several times or set hw.firewire.hold_count=0 by sysctl(1). Gavin
