Extra SSD Not Recognized
iMac mid 2011 EMC 2429
I just finished install a WD Blue SATA 6Gb/s 2.5 Inch 500GB Internal SSD Solid State Drive (WDS500G1B0A) in my iMac in the optical drive bay. I booted the computer and it is not being recognized. Any ideas as to what's going on? It's pretty simple as far as connecting the cables. I followed both he iFixit and MacSales install instructions.
