Can you put one of your >hard-drives on the end instead of using the external terminator? Not easily. It's a bigtower with the AHC in the bottom of the tower, and then going up to the HD's and then to the CD-ROM drive, and that resulted in me buying an active 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".

The airflow seems ok, the fresh air gets sucked in through the bottom, just below the drives, by means of a fan. And two fans near the top of the tower blow out the hot air. That should create a logical airflow. Thanks, I am going to get that jumper off and try rawio again. And else I'll have to buy something like a fancard to cool the box well enough, should that be it. -- Jeroen Ruigrok vd W/Asmodai asmodai@[wxs.nl|bart.nl|freebsd.org] Documentation nutter/B-rated Coder BSD: Technical excellence at its best The BSD Programmer's Documentation Project <http://home.wxs.nl/~asmodai> Another morning, black sunday, coming down again...
