"sysctl kern.cam.scsi_delay=100" isn't going to do any good because its applied after the kernel has loaded and the SCSI delay is long past. Maybe it would work (without the "sysctl" prefix) if placed in /boot/loader.conf but the foolproof brute force fix is to create a new kernel configuration and change this line, then build/install a new kernel. (example out of GENERIC): options SCSI_DELAY=15000 #Delay (in ms) before probing SCSI If one is really sweating for "maximum performance" then one would already be building custom kernels stripped of the devices one does not have. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
