Only two philips screws hold down the HD. Then you need a small torx to remove the 4 studs on the edges of the HD.
Quote from John Rork:
Do you have to remove the battery to replace the hard drive? I see a pull-tab on the drive, does it angle up?
Will the MCE OptiBay drive mount fit like in the older model?
Ditto on the request for Tri-Wing size. Just ordered a new 1TB HD, and I want to have the right tool on hand when it gets here.
