I am having problems reading some of my Compact Flash Cards with my SandDisk Extreme Firewire reader and my MacBook Pro I7 I work as a full time professional photographer. This problem has only came about in the last few days and is very frustrating.
I format the cards using the 5dmark II.
I then shoot as normal but when I connect some of my cards to the firewire reader it wont read them or mount them for some reason. When I connect these cards to the usb reader they work fine and I can down load the photos but it is very slow.
I use all Sandisk Cards, mostly the Extreme Compact Flash 60mbs 8gb cards.
What is annoying me is that some cards work and others don’t.
I have reset the PRAM on the mac but it makes no difference. I have changed the cable and it still doesn’t fix the problem.
Any other suggestions or feed back would be appreciated.
