Hello to everyone!

I faced a problem with my MBP Early 2011 (A1278)

1. System hangs and I turned it off by pressing the Power button

2. Once I power it on the white screen with flashing "?" appeared.

3. I tryied to choose the system disk by pressing Power and Option buttons but system gives me only Internet Recovery option and I didn't see HDD in Disk Utility

4. I thought my HDD crashed and I insert new SSD instesd "broken" HDD but problem stays (white screen with flashing "?" whitout possibiluty to chosse any drive)

5. Than I replaced Optical Drive by HDD with Mac OS -> and now it works but I still can not see my SSD.

The question is:

Is this Sata 3 connector (host controller) problem or I should configure my SSD to be able to operate with Mac OS??

Is there any dignostic soft or utility to check it??


Thank you!!

MacBook Pro, Mac OS X (10.7.5)

LB stands for Logic Board. On all standard Macbook Pro's there is a cable running from the standard hard drive bay to the Logic Board (the Logic Board is the Motherboard, main component in any computer). This cables fail on many model MBPs. If you put a drive of any type, SSD or standard drive, in the Main Bay and the OS does not see it then the cable has failed. Or the SATA controller or socket that cable is connect to has failed which is unlikely.

Oops - my bad - I had set the ifixit page to my own model!


Yes, if you've a 13" early 2011, that's the cable you will need.


Sorry for my misdirection!
