Dunce awk question

["William A. Mahaffey III" <wam%hiwaay.net@localhost>]

I am trying to use awk & grep to fashion a command to print out HDD 
temps, along w/ some identifying info:

[wam@4256EE1, ~, 10:41:29am] 418 % sudo atactl wd0 identify | grep Model
Model: HGST HTS721010A9E630, Rev: JB0OA3J0, Serial #: JR10046P1D5UXN
[wam@4256EE1, ~, 10:41:31am] 419 % sudo atactl wd0 identify | grep Model 
| awk '{printf $3 " "}' -
[wam@4256EE1, ~, 10:41:32am] 420 % uname -a
NetBSD 4256EE1.CFD.COM 6.1.5 NetBSD 6.1.5 (GENERIC) amd64
[wam@4256EE1, ~, 10:41:34am] 421 %

I am only *weakly* familiar w/ GNU awk, where the above works. What am I 
missing here, I expected the above to print out the model # of the HDD. 
Please apply the clue-bat generously :-) ....
