Hey, I have a problem which I couldn't solve for quite a while now... I bought a new WD Scorpio Blue 500 GB for my uMBP 13. I can't, however, figure out which screwdriver I need for those mounting screws that have to be removed in order to change the drives. I first bought a Torx 6 (Black & Decker TX 6) which is too big. I then ordered both a Torx 4 and Torx 5 from eBay. They are both too small... So what is wrong here? Anyone had the same problem? Or any alternative solutions w/o using a Torx driver? I'd really appreciate any help. Basti.
