You may have to run 67.Dq Nm fwcontrol Fl r 68several times for the system to properly detach such devices. 69.Pp 70Some (broken) HDDs don't work well with tagged queuing. If you have problems 71with such drives, try 72.Dq Nm camcontrol [device id] tags -N 1 73to disable tagged queuing. 74.Sh SEE ALSO 75.Xr cam 4 , 76.Xr firewire 4 , 77.Xr camcontrol 8 , 78.Xr fwcontrol 8 , 79.Xr kldload 8 , 80.Xr sysctl 8 81.Sh AUTHORS 82.An -nosplit 83The 84.Nm 85driver was written by 86.An Katsushi Kobayashi 87and 88.An Hidetoshi Shimokawa . 89.Pp 90This manual page was written by 91.An Katsushi Kobayashi . 92
