MacBook Pro 17" Core i7, OS 10.7.4 - I have been trying to upload photos from a SanDisk Extreme CF card (60MB/S) 16GB card. I have had both for some time with no issues. I have not changed hardware. When I plug in the reader the little blue light comes on. When I plug in the CF card the light responds normally at first and then begins to strobe - it is never recognized in Finder and will not mount. I have restarted the computer holding down the command/control/P/R keys, I have run disk utility. Nothing seems to work. I tried it on another computer and nothing there either. I tried a new firewire 800 cord and no change either. The CF card continues to work normally in the Canon 5D MkII - no signs of corruption. What can I do? Is there some way to reset something internally that might work? This reader has been terriffic and I don’t want to lose it.
I have just encountered exact the same problem - has been working fine until now.
Any help would be much appreciated - have just landed in Cambodia for work and it is so slow downloading off the camera.
Thanks for any advice out there!
