Yea, mine is internal, and real SATA.  I wonder if that will make a
difference.

Hummm... I tried "atacontrol info" and I got this:

atacontrol: 
ATA_CAM option is enabled in kernel.
Please use camcontrol instead.

So I guess I need to use  camcontrol instead.  But what command?  What
were you using with atacontrol to "re-scan"?  Was that "atacontrol attach"?
I wonder what the camcontrol equivalent to that is.  Nothing obvious is
jumping out at me from the man page.

OK.  Thanks.

I'm determined to try this, and to make it work.  Now I just need to know
what camcontrol command I should be using.
