MBP a1278 Hard Driver replacement

Hello!

I'm looking for some help. hoping for a good Samaritan to help me out with some advice.

Check this out: I have a Mac book Pro A1278 13'. The hard drive crashed, can't be accessible anymore so I bought another HD, kind of the same, but without the logo apple on it... has the S-ATA HD be compatible with mac?

My MBP has this hd installed: Momentus 5400.6 500Gb PN: 9KAG34-041 with a Apple logo close to the bar code.

And the one I got, hasn't the MAC logo on it... has to?

-- When I put my OS setup disk, if the old HD is installed, I am able to see it on the Hard Drive Utility, but when I install the new one or any other SATA HD, like for example a 250Gb Sata HD, it just doesn't even recognize that there is a Hard Drive.

I do not understand what could be wrong, been googling and seems like any SATA HD 2.5" should work on my mac, but, I can only see the old HD.

By the way: after I saw it wasn't being recognized on my mac, I got the new hard drive and I partition it in another MAC book air using a USB SATA adapter and I was able to access it, mount it, copy a file and unmount from the OS. So the new HD is working great. The old one, can't be erase, partition or formatted.

any help? Thanks in advance.

PD. I am attaching a couple of pics with my two hard drives.

Wao, no answers for me!! so sad.

well, for those that might help... I found that my new hard drive is completely compatible with my MAC, here:

But I wonder, if I need to do something in the MBP Bios, like in the PCS, that something is possible to change... any ideas of why my new hard drive doesn't appear available on my computer? I installed a different one, SATA 250Gb and as well, nothing, doesn't appear.

HELP!!! please.

I just find out that this could be the problem.

I am buying a cable for my computer, then I will let you know, but I think that's the major problem, thanks!!!
