Macbook Hard Drive Replacement

[skibob1027]

I'm considering buying a Macbook, and with the design allowing for easy hard drive replacement, I'm thinking that my first mod will be a larger hard drive (aftermarket, rather than straight from Apple). Does anyone know whether the Macbook as a 2.5" or 3.5" HDD? I know that it is an ATA150, but they come in both sizes.

Any help would be much appreciated - thanks!

2.5" It's a laptop. 3.5" drives are for desktop use.

Well, it's a 2.5 inch SATA drive, as robbieduncan said, and replacement instructions can be found in this PDF.

Thanks to both of you - I was figuring that it would be 2.5", but I wasn't sure if for some freak reason they managed to cram a 3.5" in there.

Thanks again!
