Can NCQ capability be determinded from software?

I have a Seagate disk which was an oem and Seagate's website says that
the drive "may" have NCQ capability. I'm not rabid on the subject of
NCQ but I'd like to know if it does have it as the prime reason for
this computer will be MPEG conversions from analog and I'd like
anything that potentially speeds up the process. Is there some
sniffing program out there that will make that determination whether
NCQ is enabled on the drive?

"The Effects of NCQ"
http://www.storagereview.com/articles/200601/WD1500ADFD_8.html

"Native Command Queuing (NCQ)'s impact has been something of a
mixed bag when it comes to single-user performance. While nowhere
near as damaging as the legacy TCQ found on the Raptor WD740GD and
the Deskstar 7K400, NCQ nonetheless more often than not exacts a
small penalty in performance at very low (read, single-user)
queue depths. Maxtor's MaXLine III (and DiamondMax 10) stands as
the lone offering that delivers better single-user performance
with NCQ enabled, though it is not clear whether this is because
Maxtor's implementation is truly superior or rather because the
company's drives perform unusually poorly without it."
