Chosen Solution
Hi guys! I hope you can help. I upgraded my macbook pro (mbp) with a 128 Crucial M4 SSD. So I moved the stock-320gb HDD into the optibay. This combination worked very well for a few months, but then the mbp just was not able to find the SSD anymore (like from one day to the other). The SSD is working perfectly (I tried it in another PC) and also the stock HDD can’t be found when I put it in the original harddrive place. All the cables are plugged in correctly. Also the sleep LED and the IR-sensor are working just as they should. So to sum up: Only the hdd/ssd in the optibay is recognized by the mbp. So what could be the problem? My only explanation would be that the S-ATA cable is broken, but I am not sure. And as they are pretty expensive, I better ask here. Please excuse my English, it is not my first language.
Could be the cable but you may have also burned out the controller on the logic board. Try a new cable first.
If English is not your native language then what is? Spanish meaby? I speak spanish! Anyway! Tengo el mismo problema que tú, sin embargo a mí me pasa que le instalé un nuevo SSD ya que dejó de reconocerme el HDD (que hace medio año me lo cambiaron dentro de la garantía,por lo que llevo 2 HDD hasta la cuenta);y bueno, le instalé el SSD de OWC 120G y nada,no lo reconoce mi macbook pro early 2011,i5. Yo pienso que debe ser lo mismo que pasa en tu caso.Dicen en los blogs que las early 2011 tienen ese defecto en los cables SATA,ya que fueron los primeros en incorporar SATA3…Ni modo. Update sorry, i have the same problem in my MBP PRO EARLY 2011. A week ago my macbook stopped recognizing my HDD, and then bought a 120gb OWC SSD. When installing the new SSD could not recognize, and the SSD was new and made especially for mac. I just bought the SATA cable, I arrive in a few days and I can tell you if my problem was solved. Many people say the problem is the cable and have it replaced by another and so have solved your problem. IF you have a macbook pro 13’’ early, i5, model A1278, you should read this. http://www.llegalemapas.com/beta/1.5/?t=… This is the same macbook that I have.
After almost twice a months of buying HDD cable replacement in Ebay, I finally found a permanent solution for this problem. One time I suddenly tried to look for this hdd cable replacement in Lazada, since eBay is already getting costly, I found this Generic Apple Macbook Pro Unibody 2nd Hdd Ssd Sata Hard Drive Caddy Optibay Superdrive It’s a caddy, additional drive for MacBook pro using DVD Rom drive of your mac. What a bright Idea, I never use my DVD drive so what the heck, I bought it and now Its permanent. I am using this caddy and install my SSD drive into it and remove my DVD Drive. DONE!!! FIXED!!! Hope this helps…
