MacBook Pro does not recognize my HDD
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!
