Therefore we recommend to use a good screwdriver that provides a good grip for better control and when you remove the screw make sure you put the screw driver vertically in the screwhead to prevent slipping. Because the screws are sinked in the unibody design they are difficult to extract when the screw heads are stripped. The screws that are used in the Macbooks are small and can be easily stripped. The MacBookPro8,1 8,2 and 8,3 does not reliable support SATA3 drives in the optical bay. Place them in the primary bay and the SATA2 drives in the HDD Caddy. note: recommended not to use SATA3 (6gbps) drives in the HDD Caddy with MBP 15'/17' 2011 due to compatibility issues of the unibody design. supports SATA 1(1,5gbps), 2 (3gbps), 3 (6gbps) speed supports 2TB (2000GB) SATA laptop hard drives or SSD's with max.
