    Hi all,

    On a macbook pro laptop - mid 2012/2013, I pressed the power button for 5 seconds while the system was running and it obviously shut down
    but then I when I tried to restart, it fails to recognize the hard disk

    I pulled out the Hard disk and connected to a USB enclosure and rebooted the system (with no internal drive, drive connected to USB port), it rebooted just fine.

    I am at a loss as to how to fix it.:confused:

    Sounds like the drive cable is bad. Not as common as drive failures, but it does happen. iFixit sells them for a few bucks.
