Just installed a lacie usb 3 pci express card in my mac pro running OSX 10.7.4, in order to use a lacie minimus usb 3 2tb external hard drive. I installed the driver for the card, and it shows up in the system profiler, but once the hard drive is connected and turned on, it does not mount on the desktop or in disk utility. Lacie desktop manager also does not recognize it. got the HD from amazon. Pci card brand new from amazon. LACie HD did mount once briefly the first tim I plugged it in. Thats when I realized i had no usb 3 ports, so i got some. Still no mount. wat do?
