I run a 500GB SSD as the primary drive in my MBP17...and then a 1TB in a sled in the DVD bay. Today I found a deal on 2TB 5400rpm for $80 in a case. We broke the drive out of the case but cannot get it to work internally (odd error messages) but it works fine in 2 different exteral USB cases. Anyone get a 2TB or 1.5TB working as the 2nd drive? If so what make/model? We tried it in a las model year MBP17 and a 2010 MBP15 thanks.
