MacBook Pro doesn't recogniaze my H.D.D

Hi everybody,

Thanks for looking at this topic. I will try to explain exactly what happened to my Mac book pro 13" September 2010 and wait for your comments.

I was watching a movie on my mac when it hanged and I forced to push the power button until it turned off. I turned it on again and nothing happened, no video only the light that indicates that it is on.

I searched on web and saw that people say if you restart (SMC) by pushing (shift option control power) at the same time you may be able to run the MBP. I did it and actually it was successful and I could run my Mac and being proud of my self for solving the problem began doing my thing on it and suddenly it hanged again and I had to restart it, but this time after I reset the SMC, It gave me a Folder with ? on it, which is because MBP doesn't recognize your hard drive.

I went on web to find the solution, and end up with booting up MBP with a flash memory of snow leopard (My optical drive makes sound but I don't have any control on it, most probably it is not also recognized) and try to find the HDD on disk utility and repair it.

The problem was my HDD and optical drive didn't show up on Disk Utility. I opened the Mac and took out the HDD and used a Sata to USB adapter to attach it from USB port. Surprisingly it worked and my MBP recognized the HDD, I repaired it and it said that it is successfully repaired, but still when I attached it to MBP internally it didn't recognize it. When I ran the MBP using USB port I mentioned another strange thing that my wireless adapter wasn't working! I taught that maybe also something to mention.

According to one of the posts in ifixit : Internal hard drive disk not recognized

I believe the problem should be on the internal Sata cable, but because of my optical device and also wireless adapter, I doubt a little bit on this conclusion. Does anybody have a suggestion? I am going to order that cable today and I will update you guys on the result of replacing it.

I suspect they will exchange out the logic board as they don't do component repairs (unlike some independents). Sorry it wasn't something simple.

I gave up repairing it finally and brought it to a local business in order to repair it for me. He plugged in a new HD and the MBP turned on and recognized it in Disk Utility, but it wasn't consistent! It didn't recognize optical drive and wifi still and some times it didn't recognize the new HD. He replaced the cable as well, but nothing changed, so he said it is from the logic board and I am gonna set an appointment with Apple to see what they will come up with?

Thanks for your responses.

I would run Apple Hardware Test Using your bootable USB drive reboot pressing the D key to launch it Startup Key combos.

I suspect your North Bridge chip is failing, most likely a cold solder joint. Given the fact you have both SATA connections and your WiFi are not working as well. AHT should give you an error code.

Try replacing this cable. I now stock two each on these for the 13" & 15" machines the problem is so prevalent. Save your receipt as I believe there will be a class action suit on this or a recall. Here's the part, I would not get a used one. When installing, do not bend the cables as sharply as they are now: MacBook Pro 13" Unibody (Mid 2009/Mid 2010) Hard Drive Cable

Mayer - If the HD was only effected I would agree with you as I too have found the HD SATA cable tends to breakdown over time. I just can't see that here as to have both HD & optical drive SATA cables die as the same time and the WiFi connection also going. That points me whats common between them all to focus on first.
