Do you get log entries regarding the removal of the disk in question in a timely manor, i.e. some seconds rather than minutes, like the following: Jul 24 21:13:49 flak kernel: (da0:mpt0:0:0:0): lost device Jul 24 21:13:49 flak kernel: (da0:mpt0:0:0:0): removing device entry and is it automatically detected as daX again when re-plugged?
