Hard Drives are not showing up
I have a Mac Pro Tower 2009. It will boot to a Yosemite install USB drive. BUT, when I open disk utility, no hard drives are showing up, just the USB device and DVD drive.
I have tried two different drives, in all 4 internal bays. Nothing shows up.
I have a second Mac Pro tower, fully working, I put the drives into this tower and they are recognized in disk utility right away.
Is anyone familiar with this issue?
