Because some chip set / drive combinations don't work in DMA mode (don't know why). You can list the modes your drives are currently using with the following command (as root): atacontrol mode 0 (1st channel) atacontrol mode 1 (2nd -"- ) For performance reasons you can try whether disabling DMA mode for your ATAPI devices is enough, i.e. your /boot/loader.conf should look like this: hw.ata.atapi_dma="0" Regards, Simon
