13" MBP 2008 2.53 GHz 4GB RAM I believe my internal HHD's cable has failed, I've tried two drives, along with the standard Apple HDD that came w/ my MBP and it's not finding any of them during the startup disk search. I took it to the Apple store today and the rep told me it was the HDD, which it isn't, is there any other way to tell/test the HDD cable? I purchased a new 250GB HDD to test it out and that wasn't found by the laptop either. I found the replacement cable at Fix-it.com >http://www.ifixit.com/Guide/Repair/Installing-MacBook-Pro-13-Inch-Unibody-Hard-Drive-Cable/1340/1 I'll purchase it if and try that if all else fails. Thanks for your help!
