Last week, my Macbook Pro (13", Mid-2009 model) froze. I held the power button to shut it down, and when I tried to start it back up, it gave me the blinking folder of death. I tried to boot using my Snow Leopard disk to try and repair the disk, but there was no drive except my DVD drive found. So, I brought it into a local Apple store, and the "geniuses" told me my hard drive had failed and that they could replace it for $300 (I'm 1 month out of warranty, no AppleCare). I declined the offer and bought myself a hard drive off NewEgg for $50 (Western Digital Scorpio Blue 500GB). I opened the computer up, took out the old hd and put in the new one. I booted to my Snow Leopard disk to install it, and again there was no hard drive found. I tried to go through Disk Utility as well and there was no listed hd. Is it the logic board? The hd cable seemed completely fine. Anybody got an idea? Thanks.
