So I have a friends Mac book pro here and it's not recognizing the hard drive. When I turn it on and I get the folder with the the question mark on it. So wiped the drive because my friend told me he had everything backed up on his external but that didn't do anything. It still not recognizing the drive. I bought a new hard drive cable thinking maybe the cable went bad and I installed it and it's still not recognizing the drive. At this point I don't know what else it can be. If anybody can help thank you

the ? mark doesn't mean the HDD is not being recognized, it means there is no OS on the HDD. Boot off of a Mac Install DVD or USB Flash Drive, and go to OS X Utilities/Disk Utilities and see if the HDD is shown, If it is a new HDD you can partition and format (erase) it here. Or if it has an OS on it, you can Repair the Disk Permissions.

I read two articles online that said the question mark meant it was the hd that not was being recognizing that's why I thought that what it was. I ran a DPS-test on the hd on a desktop I have and it passed. I was able to get to the OS X utilities screen and I click on reinstall OS X but it's not picking up the hard drive. Nothing shows up.

If the HDD tests fine in another computer but doesn't show up In Disk Utilities from the Boot Disk, then there is an issue with the Cable, or the Controller on the motherboard.
