Replaced Hard drive w/ SSD, now it won't start up!
I just replaced my 15" 2008 MacBook Pro core 2 Duo (200GB) hard drive with a (500GB) Samsung 840 series SSD.
I did all the data migration, and followed the iFixit manuals.
It started up fine once, so I shut it down to reconnect my printer and an external hard drive i use for backups. Now, I get as far as the gray apple screen, and then a super-quick flash of a progress bar before it shuts down again.
Putting the old hard drive back in fixes it, but that hard drive is on it's way out and I was hoping to replace it before it goes.
Any advice is greatly appreciated.
Is this a good question?
