If you're installing it internally in a MacBook Pro, then yes it will void your warranty (if you screw something up and they can tell).

Apple will tell you that as long as nothing is broken as a result of the install, the warranty remains intact. That's from both Applecare and Genius Bar people.

Just installed a WD Scorpio 320Gb in my MBP this morning.
Was going to use Carbon Copy Cloner and clone my existing drive onto the new 320 but my caddy wasn't a SATA one. I installed the new drive which took about 20 mins and was fairly easy and used my Leopard disk to boot. From there I was able to format the disk with Disc Utility and then restore from my Time Machine backup - worked a treat but won't have a backup of your Boot Camp partition.
Can anyone else who has the WD 320 installed confirm what size the formatted drive is? Mine is reading as 297.77 Gb capacity, is this what it should be?
Cheers

yep thats correct all i know is its something do with the way numbers are
calculated anyways you end up 297.77 once formated
GB vs. GiB
In the computer world, by any measurement, from any operating system, the correct way to calculate a GB as 1024^3 bytes (1024 is 2 to the 10th power, raised to the third power = 2^30) or 1,073,741,824 bytes.
Hard drive manufacturers, however, count a GB as 1000^3 (1000 to the third power) or 1,000,000,000. "Everybody does it" is their lame excuse. AFAIK, these may be the only humans in existence* who's mothers didn't ask them, "If your friends all walked off a cliff...?"
Anyway, if you do the math you'll see the difference is about 7% (1-(10^9/2^30)) which is almost exactly the difference you are seeing between your formatted size and what Western Digital printed on the size of the box.
Because the terms GB or gigabyte have been so hopelessly contorted by hard drive manufacturers, a standards body has come up with a new set of unambigious terms; Gibibyte abbreviated GiB are now being used instead. While a GB could be mean 10^9 or 2^30, a GiB always means exactly 2^30 or 1,073,741,824 bytes.
*The people who used to measure the old CRT monitors used to be in this group but I'm pretty sure they evolved into lobbyists, in which case the whole "human" thing no longer applies.
Hard drive manufacturers are deceptive when they label their drives.

You could do that, but that drive is the 2mb cache version, the WD 320 sold bulk has 8mb cache.
I dunno, I'm to lazy to google it tonight.
What I know about these things generally is that some slick lawyer will turn the real lawsuit into a class action, the lawyers will net 30% of some theoretical settlement where some number of millions of people would get $20 of the purchase of a full-price new ________ (monitor, hard drive, whatever), and nobody in their right mind would take $20 off a full price ________ (monitor, hard drive, whatever) when the going rate is going to be $100 below that number. This was exactly the scenario with the old CRT monitors, the only real result was a parenthetical note that said a 17" monitor had a 15.7" viewing area.
I believe if you look closely at a retail hard drive box you'll find some small-print notation that they count a megabyte as 1,000,000 bytes, which leads me to believe the hard drive capacity fiasco copied the CRT viewing area fiasco.
Shakespeare was right, even if he didn't realize it.
For info the Samsung 320gb is at 150 $ including shipping using EMCACAAJ
I think I'll go ahead with this one versus the WD, it's very lose in performances but uses less power, and is cheaper !
