    Is this a brand new drive that hasn't been used ever before?
    Do you have an App that can pull SMART data on the drive?
    If it were me, the first thing I would try is to format the drive to FAT32/Master Boot Record, and if that works then format to HFS+
    If that did not work, I would check the drive using a SMART app to see if the drive is healthy (which I do even if all else works well)
    If healthy but still no go, then I'd throw it in a USB enclosure, and try formatting it as an external, to see if perhaps it has something to do with the SATA cable in the Superdrive bay.

    Although it says it is all connected at 6G it is well known that 6G devices have problems in the DVD bay of the 2011 and 2012 MBPs due shielding issues. Since yours is HGST you can run HGST Tools (from a bootable CD) to re-set it to connect at 3G and it should be fine. You won't see any effect on speed with a spinning disk.

    Much more in this long thread, including a download link for HGST Tools:

    The link that works for HGST Tools is in post#30. There is a link in another post which doesn't work.
