Bad disk or cable even though >4.1 doesnt complain? Or maybe go to stable? IIRC, 4.1R did not run the U160 controllers in U160 mode. By booting back to 4.1, you effectively reduce the negotiated transfer speed and avoid stressing the bus to the point of failure. The moral of the story is that some part of your bus is not up to running at 160MB/s. It could be the cable, or the terminator, or the bus length. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
