Stripped screw when installing second HDD, replacing Optical Drive Bay
I was trying to install the second drive bay and substituting the optical drive bay...
In this tutorial step 8: MacBook Pro 15" Unibody Late 2011 Optical Drive Replacement
I could not get the two screws out. They were really tight. I used a Phillips #00 screwdriver as stated in the required tool, but ended up stripping the screw.
I gave more attempt switching to the flat head and it made it worst. Now it almost has no more x marking... And I am desperately finding a way to get it out.
I tried the rubber band method, but the screwdrivers just goes right through... It stripped a little more everytime I put pressure on it unscrewing it.
If you have room try using a jewelers drill to grasp the outer wall of the screw. If not, time for the drill. Mask off the area really well so the metal shavings don't mess up the works. Use the smallest drill to get the head off then try the jewelers drill again to grasp whats left. If that still doesn't work you'll need to drill and tap the hole for a replacement screw, be careful here as the alignment of the hole needs to stay the same.
