dimma at clh0 15:09$ sudo grep -iE "(disk|ata).*(disk|ata)" /var/run/dmesg.boot 
ata0: channel #0 on atapci0
ata1: channel #1 on atapci0
ar0: 76319MB <ATA RAID1 array> [9729/255/63] status: DEGRADED subdisks:
 disk0 READY on ad0 at ata0-master
 disk1 DOWN no device found for this disk

I has DOWN ad3. Not ad0.
Is "atacontrol status" -- wrong?
Why he report "ad0 down"?
