Hi Guys,
I have a 13" a1278 MBP unibody mid-2009. 2.16 Ghz Core Duo
When I power up my MBP, it hangs at the grey screen. There was a time I could occasionally get it to boot into OS X, but it would hang before I could get anything useful done. And I do mean HANG. Nothing worked at all, not the mouse, not Finder. It didn't even detect a kernel panic. Just nothing.
I was able to loot all the data on the HDD using target disk mode, but when I try to boot using the HDD, it just hangs on grey. It does not give the folder with question mark icon, it either shows nothing but grey or it hangs on the apple logo with the spinning icon. I was once able to run diag from the OS X install DVD, but no more. I cannot even boot to the install DVD. (Diag found nothing wrong).
I tried disconnecting the HDD, but still could not boot to the install DVD. I also was not able to boot to the install DVD over firewire using the working disk drive on another mac in target disk mode. (I put another mac in target disk mode, ran a firewire, but could not boot my MBP to the install DVD on the other mac.)
This problem seems to be getting worse and it seems to be a problem with both the HDD and the disk drive. Is it the I/O controller or the HDD? Could it possibly be the disk drive?
I've reset the PRAM and SMC without any luck.
It also took several tries to get all the data off the HDD in target disk mode, as both computers hung one time, and other times there were problems with permissions.
I want to say its the HDD, but wouldn't I be able to boot to DVD with the HDD disconnected?
Please help?
