MacBook Pro doesn't recognize replacement hard drive.
I am having a very weird problem with my MacBook Pro 15'' Mid 2009 model.
I recently damaged my hard drive, so I decided to buy a new one, which is exactly the same model as the one that I had. A Seagate ST9500420AS 500 GB 7,200 rpm.
Now the thing is that, although my previous drive is damaged, it can still be recognized by the disk utility when I boot from the Snow Leopard Installation DVD. On the other hand, for some reason, the new one is not recognized by the Disk Utility! What's more, I connected an older hard drive that I had, with Leopard installed in it and still it doesn't recognize it. But If I connect it to the USB, it recognizes it and it can boot normally to MacOS....
Isn't it weird? To recognize only the damaged hard drive?
Does anyone have any suggestions? I am dying to get my laptop working because I have many things to do this period. I appreciate your help.
Is this a good question?
