I would probably be better to spread your devices across the whole bus then to have this dangling stub. Can you put one of your hard-drives on the end instead of using the external terminator? > disk4 = > da3 at ahc0 bus 0 target 4 lun 0 > da3: <SEAGATE ST32171W 0484> Fixed Direct Access SCSI-2 device > da3: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing > Enabled > da3: 2047MB (4194057 512 byte sectors: 255H 63S/T 261C) > This drive has Term Enable, Term From Drive and Term To Bus set. You should not set "TP to bus".

Even with a degraded bus, it is rare that a device will fail a selection. Are you sure that this device is running cool enough? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
