It *should* be possible to simply set the control mode on those two disks (``man rc.early'', ``man atacontrol''). Unfortunately, the problem is noted as errata in several FreeBSD versions tending to appear on SATA disks. I believe this is also a problem with some linux setups. If you google ``FreeBSD hw.ata.ata_dma RELEASE'' you will eventually find the following page relating to Asus motherboards: http://www.ryxi.com/freebsd/63-668-write-dma-other-similar-errors-read.shtml I picked it out based on the following line in the dmesg output: > Nov 29 20:46:09 elfi kernel: ACPI APIC Table: I'd say it's worth a shot. You might even try turning both the flags off temporarily to see what you get. Your guess is as good as mine. :) -Michael
