I am trying to swap out my current internal 160GB SATA HD from my Macbook 13in unibody late 2008 (macbook 5.1) to a WD 500GB SATA HD. I have been looking at instructional videos as well as reading on how to "clone" my old 160GB and transfer the data onto the new 500GB HD. I have been using a sabrent usb to sata cable to connect my new 500Gb via usb to my macbook with Super Duper. I have followed the steps on how to prepare my HD by going into disc utilities and erasing the drive, making sure its formatted to Mac OS extended journaled. Once everything is complete I test it out to see if it boots up from the new 500GB using the sabrent cable, and works fine with no problems. Now I can actually install the 500GB into my macbook and boot up from there without any problems right? Well when I boot up I get the flashing folder with a question mark. I was thinking maybe I did something wrong so i tried it again and i get the same results. I even used Carbon copy and still the same issue. I am I doing something wrong here or forgot a step?
