2010 Mac Pro hard drive not seating
Hello all...I have a 5,1 model 2010 Mac Pro, and I'm trying to add a couple of hard drives to it. The drives are from external drives that I tore down. They look like typical SATA drives and are Western Digital Caviar series 3.5".
They mount on the sleds fine, and slide in, but don't seat into the connectors. almost as if there's a misalignment.
Any insights?
