So I bought a new 1TB Seagate SSHD (hybrid) drive for my 2010 13" MacBook Pro and after cloning and installing it won't boot. I am stuck with the folder with the question mark on it. Here were my steps: 1. Mount the new drive into a SATA USB dock and connect to MacBook 2. Formatted new drive as OSX Extended Journaled 3. Used SuperDuper to clone existing drive 4. Rebooted MacBook holding down Option key and selected the "external" Seagate drive. It booted just fine. 5. Swapped out drives and it won't boot. It doesn't feel or sound like the new drive is spinning up. I put my old drive back into the MBP and it boots up fine. With no drive in the MBP but the new one in the dock I can hold down the Option key and it shows up as a bootable drive Any suggestions at all??? Thanks.
