Internal Seagate 1TB Hybrid boot drive not recognized
I'm trying to install a new hybrid drive in a Macbook's standard HDD bay. I formatted it on a Core i3 iMac, and installed Mavericks. It works fine externally (via USB) and will boot on the iMac. But the Macbook Pro (Core 2 Duo) does not recognize the boot partition, and just shows the folder [?] on startup.
There are two partitions on the drive (300GB and 700GB). Seagate says the SATA III is backwards compatible, but Mayer here suggested using a jumper to drop the transfer speed. I'm not sure how best to do that (can I just fashion a jumper from a paperclip?) or if it would work on this model.
Is it possible the Core 2 Duo will not support a drive this large? Thanks for any responses.
Es esta una buena pregunta?

UPDATE: I was able to startup the Macbook from this new drive externally) (using my iFixit USB adapter!). So it is not a compatibility issue, but a problem with the internal connection I would think.
The original hard drive had mechanical failure after being dropped. Could that have damaged the internal cable as well? Seems a remote possibility.

ADDITIONAL UPDATE:
- Installing a new HD cable did not solve the problem.
- An older HD (SATA I) worked fine when installed in the drive bay.
- Putting a jumper on the 2 leftmost pins of the 1TB Seagate drive did not solve problem.
I am reluctant to reformat the 1TB drive as a single partition, but that's the last possibility I can think of. I'll probably put it into an external case and get a smaller, slower drive for internal use.

SUCCESS AT LAST: Seagate drive working as intended. The SATA cable and connection are fine. Must conclude that the problem was in the drive itself, and the way it was initially formatted. Further comments below.
