So I purchased a new 2TB drive (Samsung model #ST2000LM003) for my 13" MacBook Pro. No issues with the old one, just getting close to capacity. I connected it with a SATA/USB adapter, formatted it, and copied everything over with Carbon Copy Cloner. The transfer completed successfully, and the recovery partition was cloned successfully as well. I then verified the disk (no problems) and permissions (a few problems found and repaired successfully). The new drive boots fine over the SATA/USB adapter, but behaves very strangely when installed.
If I try booting normally, I get the folder with flashing question mark logo. Resetting the PRAM doesn't help, and it's not an issue with the SATA cable or logic board since the old drive still boots fine internally. If I hold alt/option while booting, the only choice provided is Internet Recovery. Even if another bootable USB drive is connected (including the old hard drive), Internet Recovery is the only option. I looked in Disk Utility through Internet Recovery -- the new drive (installed internally) does show up there, but its partition scheme is listed as Master Boot Record which is wrong (it's definitely GUID). Rather than the 2TB partition I created, it shows a single 250GB partition with a generic name. The verification buttons for the disk and the partition are all greyed out.
At this point I'm completely stumped, any help would be greatly appreciated.
Thank You
