However during Snow Leopard install I get an error message about 10 min into it saying Install Failed OS X could not be installed on your machine. I was able to find the drive under disk utilities and partition with GUID no problems. The install went fine and I had a Snow Leopard disk in the drawer to boot with. I did have my drive backed up on Time Machine, but the new SSD had to be installed cold turkey. I looked over reviews and decided on the Samsung 850 EVO SSD. My hard drive failed on my 2009 MacBook Pro last week.
