I have a problem where the Yosemite install does not see 240GB Mercury 6G Electra SSD during an install from the USB drive.
I'm using a USB thumb drive installer. It boots up fine. Except that when I get to the page where it asks you what drive to install to, all I see is the USB drive itself, and no SSD.
I triple checked that the SSD is installed correctly. I put it into the machine straight of the box, brand new.
