Why can't my late 2011 17" MBP use a SATA III SSD in the optical bay?

    When I first got my late 2011 17" MBP it came with a 750GB 7200RPM drive that I quickly replaced with a 512GB SSD. I removed the optical drive and replaced it with the 750GB factory drive. Last week I bought a 1TB SSD drive and was going to replace the 750GB drive with it.

    However it appears that the optical bay sata slot does not support sata iii even though it is listed as such. I keep getting disk needs initialized but when I try to format it I get the message. "Disk erase failed with the error: Wiping volume data to prevent future accidental probing failed."

    Anybody got a solution?
    Can I force my mac to only use SATA II mode on the optical bay?

    Thanks in advance for the support.

    Well known problem. While the optical bay can handle a sata III HDD, it won't work with a SSD. No way to degrade the interface to sata II. Only option is to buy a sata II SSD, available from OWC, and install it. If you're just looking for disk space you could move the 1 TB drive to the main bay and keep your original drive in the optical.

    Thanks for the links. Seems like a bit much. Guess i might just install a blu-ray drive.
