WD Scorpio Blue 750GB 2.5″ hard drive height

I want to know the height of the Western Digital Scorpio Blue 750GB 2.5″ SATA internal laptop hard drive. The “Product Description from the manufacturer” on Amazon.com’s product page says it’s 12.5mm. That’s the info provided directly from WD via Amazon.

However, visit the product page on westerndigital.com and the height is 9.5 mm.

This makes a big difference for my Macbook (Early 2008). It can’t take a 12.5mm hard drive.
