  1. Hi OWC, Can I ask how do you move your files on your bootdrive SSD to HDD? Do you just drag and drop to the 'Macintosh HDD' under the device column?
    And how do you open those files that you have moved to HDD while booting from SSD? Do you have to restart to boot from HDD to open it?
    Does it work the same round from HDD to SSD too? As I only have a 250GB SSD and a 500GB HDD from Apple, I am planning to boot it from HDD and copy only important files to SSD. Please help me!

  2. You should also disconnect the battery before working inside the computer. Also, the 4 smaller screws along the opposite side of the 3 long ones are sometimes different than the remaining three. So you should keep them separate too.

  3. So after I replace the cd drive with the extra hard drive, what happens after I turn my MacBook back on? Will the extra drive just show up like an external disk or what and will I need to reprogram anything?

  4. Both the optical bay and the main hard drive bay have a drive bus of 3.0Gb/s. Given that the speeds would be the SAME in either bay, the HDD was installed in the main bay as that bay itself offers an added SMS benefit. So really, no need to cringe 😉

  5. crrrrrriiiiiiiiiinge when they didnt use the old hard drive in the optical bay . that one is A 3GB/s transfer rate . the originally being used by the hard drive had a faster transfer rate
