Replacing hard drive with 3 mounting screws?

[hook 'em]

I'm replacing my hard drive on my 13MBP and for some reason my T6 screwdriver wont work on my last mounting screw.. will it work if i only have three? im going to buy a t7 screwdriver but if that doesnt work then im SOL.

I just had this happen to me on Friday, and the 4th screw was stripped before I even tried to loosen it. I will say noise/vibration seemed to be fine with 3, but I'm OCD with stuff like this. I went in to the Apple store the next morning, but they didn't have any in stock and wound up pulling one out of their machines in the back for my replacement.

PS If you don't feel like going in, the guy who helped me used what looked like a needle nose pliers to get it out.

You should never attempt anything related to computers without the proper tools. But it should be ok and I could contact Apple for a replacement screw.
