When the cache fills up in a certain way, the drive forgets about transactions including newly queued ones. You should contact Seagate about getting the latest firmware. In the mean time, you can disable the write cache on the drives with old firmware (the one with firmware rev 0006 should be okay) from the SCSI-Select menu. BTW, although the driver reports a drop to 3.3MB/s, this is only during a small window while it renegotiates with the device after a bus reset. Once the negotiation is complete, the device is handled at the full 80MB/s rate. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
