I don't have a whole lot to add to this thread, but have changed the subjec= t=20 to make sure that the right people are reading this. This is likely either= a=20 hardware problem (motherboard/cable/drive) or driver problem. GEOM and the= =20 mirror driver seems to be behaving as desired (it detaches a drive reported= by=20 the driver as being bad). Could you post the dmesg -v output for the probi= ng=20 of the ata controller and driver? Robert N M Watson Computer Laboratory University of Cambridge --0-1838797900-1152793564=:61840--
