I am upgrading my HDD on my 2011 Macbook pro, with a 750Gb Toshiba MK7559GSXP I used CCC and SD to clone the drive , the cloning process finish with out any flaws, afterwards I tested the Clone HDD by restarting the computer and pressing the option and booting from the Clone HDD, it work fine, I proceed it to install the HDD on my 13" Macbook pro, I restarted the computer and after 60 seconds all I get is the Flashing folder with the question mark, I remove the HDD and install the old HDD and boots fine.
can this be related to the open firmware password?
