I tried both >From which manufacturer are the disks ? I have only seen one problem so far with the 1742. It seems to have troubles under FreeBSD if the disks are slow speed ( <= 5Mb sync) disks. Under DOS the speed you set up with the EISA config are honored. But i suspect the driver under FreeBSD doesn't care about that.

I tried using each of them separately and two together. I have to check what happens if I change the transfer rate (currently set to 5MB/s). Thanks for the hint. BTW, what rate do you use? Serge
