Compact flash cards stopped mounting to Imac and macbook pro. I have tried both a reader and directly from the camera.
I am a photographer, and I do the same thing every single time I load pictures, I use a Targus card reader for my compact flash cards and load them that way. I have a 2011 Imac. and a Nikon d700 camera. I use a variety of compact fash cards. I purchased a macbook pro 3 weeks ago. Yesterday, I tried to unload my photos using the card reader to the macbook pro, and it wouldnt mount, so I hooked the camera directly to the computer, still wouldn't mount. When I got home I tried it on my imac, same issue. I have done this literally hundreds of times and now there is nothing. I have checked all the tabs in finder, and all appropriate items are checked. Nothing should have changed since I last uploaded photos, but nothing will work now. I have tried 3 different usb cables, and many different cf cards. Nothing will work on either mac, However, it all works on my crappy old gateway laptop. Any help would be appreciated. I am at a loss, and I need this to work for my business! I will warn you I am pretty un-knowledgeable when it comes to macs and anything very advanced.
iMac, OS X Mountain Lion (10.8.2), same issue on Macbook Pro
