Mac HDD Firmware for non-Mac-HDDs? First of all: I use a MacBook (white) 13.3" 2Ghz (It says it's a MacBook3,1).  

There was an 80GB HDD (Hitachi) built in, which just turned out to be a little too...
Well, it's not enough anymore.
So I cloned the drive with Carbon Copy Cloner (can recommend it by the way) to a 250GB FUJITSU MHY2250BH.  

Now it has been my understanding that I need a special Mac Firmware for the drive to use certain features, for example the HDD temp display the iStat dashboard widget usually gives me. Google couldn't come up with anything useful so far, so here's what the question actually is about:
Can I get the drive to be "fully functional", e.g. with some Firmware upgrade or something else?

If I am completely wrong with any of my assumptions – pointing that out would be an acceptable answer, too.

EDIT: Just to specify: The HDD itself works, but there are some minor inconveniences left:
The system boots slowlyer and iStatPro can't display the HDD's temp.
You do not need a special OSX firmware to use a different internal disk. Just plug it in and all will work.
