Since a week, I can’t get my MacBook Pro to recognize my HDD. When I use the install dvd, i can’t select my HDD and with Disk Utilities, i also can’t see the HDD. I tried another new HDD but it didn’t work also. Both drives work when I use it in an USB SATA external drive. What part do I need to replace for my MBP? Update Just replaced the HDD cable but with no luck. It must be the logic board then. Thank you for your time guys!
Replacing the hard drive cable may solve your problem. Here’s the one for the 2009 model: MacBook Pro 13" Unibody (Mid 2009-Mid 2010) Hard Drive Cable
C Ata - did you have to replace the logic board? Is that the same as the motherboard … if so how much was that?
