Macbook pro cannot read my CF cards
I am using 10.7.5 I am using a USB 3.0 RAW STEEL UDMA reader and I cannot import any photos. I am getting a message that says the card cannot be read. It does not matter what brand card I use. The images are on my camera but when I try to import into lightroom or just find the drive in finder, they are not there. I format my cards in camera every time I use them. There is obviously something going on that is causing this problem with many photographers, as I have seen many other people having the same issue. Any help would be greatly appreciated.
