This was my operator error, the correct sequence for hot swapping this firewire hard drive on my motherboard is this: (this is with firewire and sbp devices compiled into my kernel) ... plug the firewire drive cable in run 'fwcontrol -r' mount the firewire drive do backups unmount the firewire drive unplug the firewire drive cable ... My PC and firewire drive would work fine on the first time plugin of the hard drive, but unplugging the drive and coming back later to plug in again needed the 'fwcontrol -r' to work properly. YMMV Another person also passed this tip on to me, he had been having trouble getting a different firewire device to hotswap and had better results using the firewire and sbp devices as kld's. With a kernel without firewire or sbp devices compiled in: kldload /modules/firewire.ko kldload /modules/sbp.ko mount the firewire drive do stuff unmount the firewire drive kldunload /modules/sbp.ko kldunload /modules/firewire.ko Thanks to all who helped.
