This is barely pertinent to the original discussion, but I still use
hdparm -[U|R] to enable/disable an interface and attach/detach an
optical drive on my laptop (Dell D800 - not that new or fancy anymore).

It works fine, as far as I can tell, once you get udev to have the
devices in /dev/ for you

Partial uname:
2.6.11-1.27_FC3 #1 Tue May 17 20:27:37 EDT 2005 i686

Hopefully they haven't disabled it after that, I'll be disappointed.

I do agree in general that SMART support for SATA at least should be in
kernels by this point, and correct error propagation as well. Perhaps
all the kernel devs either don't get the new hardware, or they're on
SCSI though. I'm still building with PATA until SATA's got it all anyway.
