mounting hard drives , mac pro I Just installed my new western digital 640GB as my maine boot drive. On my shinny new mac pro, works like a charm. With my stock 320, I gave her a patron. One for storage and one for a virgin install of leopard and soon my first windows os in 10 years. With both my wife and my kids clamoring over who gets to use the new mac. I felt it's best. Just to unmount the other disks to avoid any confusion or accidental corruption or loss of data. Is their any way to get these to mount and be seen by the mac pro with out restarting.
