Ok, it took me a while, but now I remember why this was dejavu. I saw the
same thing on a similar setup. The one maxtor ata 133 was working fine. I
added a slave, and all of a sudden errors on both. Not sure if its the
maxtor or issue with ATA133. But I fixed the problem by forcing everything
down to ATA100.
I have this run at startup time
/sbin/atacontrol mode 3 udma100 udma100
where 3 is the channel on which I have
# atacontrol info 3
Master: ad6 <Maxtor 4G120J6/GAK819K0> ATA/ATAPI rev 6
Slave: ad7 <Maxtor 4G120J6/GAK819K0> ATA/ATAPI rev 6
and all has been happy for months. Also, double check that the jumpers are
correctly set on all your IDE devices.
