Problems with SDHC Cards in MPB
I have an early 2011 Core i7 MacBook Pro that will not read SanDisk 16GB Class 10 (30mb/s) memory cards via the card reader. I can read PNY 16GB Class 10 (20mb/s) memory cards via the card reader without any problems... and can read the SanDisk cards in my MBP via an external USB card reader.
I have gone around and around with Apple (via AppleCare, Genius Bar and the Apple forums), but have been unable to resolve this issue. Based on my experience, I believe this is a software/driver issue and not a hardware problem... and there are many others with similar experiences described on the Apple forums. Some have even stated that one of Apple's upgrades cause this issue to manifest. I cannot confirm that part of the story, but who knows? And Apple is playing dumb - as they are wont do to with this kind of issue until they have it resolved - then they can ride in on their white horse and save the day...
One question that was raised was, that if it is a software issue, might it be resolved with OSX 10.7 (Lion)... so my question - is there anyone here running a beta release of Lion that could check this out for me? If this issue will be resolved with Lion, I can live with the issue for now. If not, I need to figure out how to proceed... I love the fast, high capacity memory cards for my Nikon DSLR, and would hate to have to use slower cards just to accommodate my MBP.
Anyone able to test this for me?
