Leave the 120 GB HDD in your machine for now.
Put the new 750 GB HDD in the enclosure you received from OWC. And attach it to your Black Book via USB. Open Disk Utility and format the 750 GB drive as HFS+ using the GUID scheme. Leave it in the enclosure for now.
Next, go here
and download|install Carbon Copy Cloner on your old hard drive. (It's donation ware) Now use CCC to clone your old hard drive to the new 750 GB in the enclosure. CCC will make the new drive bootable.
Next... See if you can boot the machine from the 750 GB drive in the enclosure. Reboot, hold down OPTION key and choose the external to boot from. If it boots OK, proceed.....
Remove your old 120 GB hard drive from the machine and replace it with the 750 GB HDD. Reboot. If you've done everything correctly, the machine should boot normally from the now new internal 750 GB hard drive.
Just make sure that when removing the old drive and replacing it with the new one that you don't break anything. Be real careful.
Let us know.
