But only if you replace the drive or  null-out the first sectors. If the drive 
comes back after a reboot (the same drive) then you end up having two raid 
arrays.
That's not what I call a working raid support!

No, if you create a raid array with the controllers BIOS FreeBSD doesn't care 
about. Also of you Shutdown the machine, power on the machine, modify files, 
power down, reconnect the drive and power up again FreeBSD (and the 
controller) don't recognice the broken mirror and FreeBSD ist panicing!
Regardless wether it's the vendors fault or the ataraid fault, it doesn't work 
so this should be mentioned!

I know and I have one running here, but that's not a reason to list 
controllers as working when they are not.
Not to mention the completely broken ataraid in -current.
