I just replaced my stock 160GB 5400rpm hard drive with a 500GB 7200rpm drive using iFixit's guide. I noticed after the fact that there's a metal disc stuck to the hard drive that maybe should be transferred to the new drive as well. Has anyone else noticed this? Any idea what it's for? Since the new drive has a higher rpm I'm concerned I might need it for heat dissipation.

Assuming the metal disk you are talking about is the one pictured in this photo:

No, the disk stays on the drive.
Make sure your new drive is secure (not loose).
Use software tools to watch your HD and processor temps. Any increase in one can drive an increase in the other.
Temperature Monitor.

Thanks - any idea what the disk is for?
Maybe to transfer heat away from the hub of the drive to the rest of your machine? ______________ I would _guess_ that it may be specific to that drive family. __________ Ask the TV "Good Question" guy.
About that picture - http://s1.guide-images.ifixit.com/igi/Ml.... ________ Did you take that picture?___________ In that picture the gray circle looks like cloth rather than metal. There is very sometimes a filter, made of some kind of synthetic cloth-like fiber on some hard drives, and some companies put it on or near the hub of the drive. Disk drives are not air tight or pressurized, like canning jars and airplanes, some small amount of air goes out and in as they heat up and cool off. There is no way I know of to make such a filter out of aluminum or any other metal that is not super expensive (they are called micro sieves - and they can do amazing things, whoops, off topic), but if you could, that would be great, and it would look just like the disk on your HD.
I'm guessing that it might be to transfer heat, or distribute any force that might be applied to the drive spindle, which is why I was concerned that it should have been transferred. So far my iStat widget is reporting the hard drive at running between 42 and 48 degrees Celsius. It's among the lowest of the temperatures reported, so hopefully that's fine!
The picture is iFixit's own photo (see domain name); the disc is definitely metal and between .5 and 1mm thick.
