Need Advice: Opening computer hard drives from laptops

What do I need to buy to loosen the extremely tiny screws found on a computer's hard drive? I think both of my hard drives that I have are from laptops. My standard hex wrench set, both English and metric, are no where near small enough. What do you guys use to open these things? I am just trying to get any gold pins or fingers out, circuit board, the hard drive plates, and any aluminum. Hammering until it comes apart might ruin these things, right? I tried to add photos, hopefully that works.

I found this, but is this what I would need?
7-piece Precision Torx Driver Set

Thanks ahead for the help.
