Built in SD Card Reader Stopped Working
I have been using the built in SD Card Reader on my MacBook Pro 13" (mid 2009) with numerous SDHCs--from Class 4s to 6s, from Kingston to generic ones. Today it stopped working for no reason. A few days ago, I needed to reinsert a card multiple times before my laptop recognized it. Today, it stopped recognizing the card at all--no errors whatsoever.
But when I use an external card reader, my MBP is able to mount it. I tried numerous cards, but no luck: all are unmountable from the built in card reader but readable from my DSLR or Wii or USB card reader. Could I have a faulty built in SD card slot? Repairing permissions didn't help. I ran a quick AHT but didn't find any errors. I'm doing an extended test in Apple Hardware Test at the moment.
For the skeptics, yes I made sure that the cards were inserted properly. I recently upgraded to 10.6.3 if that makes any difference. I hadn't had this problem in 10.6.2.
