The drive has us still in datain phase, we're happily looping to accept incoming data bytes, but none are arriving. This is likely due to a lost "ACK" on the bus, so the target believes that there is no space left in the synchronous offset to send more data. Replace your cable, check your termination, etc. etc. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
