I am trying to add a SSD to my computer for a DIY fusion drive. I'm using a 250gb Samsung 830, and the OWC cable kit. After I installed the drive, my computer refused to boot. If I disconnect the SSD, the iMac will boot normally. I tested the SSD in a USB enclosure, so I know it's not faulty. I disconnected my optical drive and tried plugging the SSD into those terminals on the motherboard, but got the same results. Has anyone had similar issues?
