Hard Drive not recognized, even after replacing HDD cable
Ok, so here's a weird question for you all! Normally I don't do these forum things, but I am backed into a corner!
First my MacBook Pro won't show the Apple logo, second, it doesn't see ANY hard drive EXCEPT Windows NTFS drives! I know right!? VERY WEIRD!
So I bought a brand new cable, installed it and low and behold, NOTHING changed! Still doesn't see any Apple HDD and ONLY see's a HDD with Windows OS installed, and no it won't boot to anything!
I insert my Yosemite install USB, it goes through the first install point with the Apple logo and install progress bar, then goes back to blank grey screen. Nothing else happens.
Install DVD with Snow Leopard on it, insert it, it does the same thing, goes through the spinning wheel thingy, then goes to a grey blank screen.
I have reset all PRAM, NVRAM, SMC settings, the whole nine yards. So at this point, I am pointing towards the logic board as the issue!
It turns on, NO APPLE LOGO, does the hardware OK normal Apple chime, then does nothing unless you are holding down OPTION at boot to select a drive.
I reformatted three known working HDD's three different manufacturers, and two 5400RPM's and one 7200RPM drive. I have not tried an SSD, I have three, but only one to try.
Is this a good question?
