Hi all, just wondering if anyone else has had this problem. I know there are dozens of posts about SD cards not working with MacBook pros, but mine seems to have started when I installed the latest Lion update.

The SD card on my Nintendo 3DS was not working. I had to replace it so that I could play the games I had downloaded via the eStore. The repair was a challenge mainly because I stripped a couple of the small screws when trying to get inside. I finally had to use a drill to get past those 2 screws.

I have a high-end 13' early 2011 MBP and the cards I'm having trouble with are all Sandisk 4GB SDHC. Two are 'Extreme III's' and one is an Extreme II. The card reader is showing up in System Profiler, and a really old 2GB Sandisk card gets read fine, so there doesn't seem to be anything wrong with the MBP hardware.

Similarly, I can read the cards fine via a USB adapter, so it's not the cards that are causing the problem.

I had successfully imported photos from the cards before upgrading to Lion, and also before installing the 10.7.1 update. So, it looks like the problem may be linked with the update, but this is purely an educated guess.

I've tried resetting the SMC to no avail.

Has anyone else experienced something like this?
