Replaced hard drive and now new drive is not booting up
Hi, I have a MacBook 13" intel Core Duo processor. I previous had a 120gb fujistu hard drive installed. I purchased a 320gb western digital hard drive to replace it. I cloned the drive and followed the procedure to replace the drive and when I placed the new drive in, it did not recognize the drive. I placed the original drive back and it also did not recognize the drive. I placed the new drive in an enclosure and it booted up from the USB port.
Does this mean that the HD cable to the logic board is bad or is there another process that i'm missing.
Is this a good question?
