Updating drive firmware for end users is pretty rare (and almost all
tools are still DOS based ;-)).
Certain drives should default to non-NCQ (based on model), but we
should be able to enable it if the firmware supports it.
Most of the newest drives are fine, but we will still need something
like Tejun's fix to be able to turn it off for the odd cases that
show up in certain odd applications, etc.
Ric, can you press harddisk vendors hard enough such that those model
and revision numbers squeeze out of them?
Thanks.
I will certainly push to get drive vendors to work with us on this. It
is in everyone's interest to have the drives avoid stressing features
that are not stable ;-)
Even better, we can usually try to work the bugs out with vendors before
the drives become public which should help minimize the issues.
