I have a friends I-Mac 27" 2011 that I am trying to get running after the HD died.
I installed a new one. new drive is a 4TB SATA 6Gb/s 3.5-inch. I installed it with an "In-line digital thermal sensor for IMac 2011" When I try to start it up it seems to be going normally and when the startup is complete the screen goes black for a second then to a blank white/grey screen. I have tried starting it from a bootable flash drive, and using internet recovery. Both yield the same results, ends up in the blank white/grey screen. I have an original Snow Leopard instal disc that I tried, but it reads the disk for a while and then ejects it. I connected it to my computer using target disk mode and formatted the HD. The HD seems to be operating normally when I have it in target disk mode connected to my computer.
I have an external HD with a good Time Machine backup of his old HD. I also have another external HD with a clone of his bad HD that I made while it was still working, but I'm not sure it's any good. The old HD had bad sectors on it.
