I have a macbook pro (2009) which was dual booted to windows. Windows bluescreened, I restarted, and the mac woulnt boot (blinking folder question mark). I pulled the hard drive out, copied the data that wasnt backed up, made a bootable osx installer and booted from that.
The laptop went to a prohibition screen (stop sign) https://support.apple.com/en-me/HT204156
I then booted gparted, but it doesn't see the hard disk, which is healthy according to SMART and I formatted it to NTFS. I am worried now. I was hoping it was the hard drive.
sudo fdisk -l
Does not show the disk either.
Is this a hardware issue 100% certainty?
This person here claims that it could be the HDD cable: https://www.youtube.com/watch?v=k1IiEe7TSKg (ps I love his accent).
Any way to know if it is the cable or is it likely the motherboard? Gparted ran fine. How can I know for certain it is not the motherboard or the harddrive?
