How do I unlock the hard drive bays in Mac Pro Early 2008
This morning I opened up my MacPro to replace one of the four hard drives. The drawer was very stiff, and I started playing with the grey tab above the bay. Next thing I knew, there was an orange color showing next to all the handles for all the bays. I'm assumning I somehow have locked them, but there is no info online of how to unlock.
Mac Pro, OS X Mountain Lion (10.8.5)
