The laptop stopped recognizing the hard drive, I searched around for solutions, it all seemed to point to a failed hard drive cable
I ordered a replacement cable from ifixit, I live in the Caribbean, received the replacement part in less than a week, the swap out was very easy to do, and now my laptop is running like new again.
I tried other quick fix methods that I read about, and as quickly as it was fixed, it stopped working again. That is when I decided to buy the replacement part, and I am very happy I did.
