Apple MacBook Pro will not read SDHC memory cards

->> There seems to be a problem going around with SDHC cards and the latest Mac OS X 10.7.1 (Lion) update or possibly some other update on Lion. Active thread here on Apple's website, there are related threads on the right-hand sidebar of that page. https://discussions.apple.com/thread/3275447
I've got a late 2010 MacBook Pro unibody running Mac OS 10.7.1 on it. I installed the 10.7.1 updated most likely on 8/17/11 the day after it was released by Apple. Since then I was able to read SDHC cards as I shot a number of photos and videos to my cards and they worked fine.
I'm not sure what has changed since then, it wasn't as simple as the 10.7.1 update then it didn't work. This is the problem I'm having below, just started to experience this on 9/2/11. I tested with two 32GB SDHC cards, one 16GB SDHC card and one 2GB SD card. All cards were manufactured by Transcend.
Anyone else have this problem?
FAIL:
* SDHC cards (16GB and 32GB) will not mount and aren't recognized by the MBP via the built-in SD card slot
* SDHC cards (16GB and 32GB) will not mount and aren't recognized by the MBP via SanDisk 2.0 card reader connected via a short USB cable.
* If I put any SDHC card into a SanDisk USB 2.0 reader that is connected to my USB hub (I gave it a try in case there was a power problem with the MBP USB system) the card is not recognized either.
* Even Disk Utility will not see the card when inserted via built-in card slot or a reader.
SUCCESS:
* SD cards (2GB) mount fine when inserted either in the built-in SD card slot or via my SanDisk USB 2.0 reader.
* If I leave the SDHC card in my camera (Canon 60D) and connect the camera to my MBP via USB I can import the images via Aperture.
* If I put the SDHC card into the memory card slot reader of my HP inkjet printer (it has multiple card slots for different types) the card will mount normally like it is supposed to via the two failed methods above. |

| ->> Baron, I've used the SanDisk Extreme Pro 16GB SDHC UHS-1 with my 2010 Unibody MBP 13" and i regularly use the SD slot on the side. The camera i use it in is a Fuji X100. Works fine for me, and yes, I'm running 10.7.1 |

->> Yeah, worked fine for me up until Friday. I don't recall Apple pushing out any updates since then that would affect this. Seems like it forgot how to read SDHC cards or maybe power on a certain pin got shut-off via software bug.
Cards have been formatted, low-level formatted several times for these tests. I've tried
*UPDATE* I just tried the SDHC card via a cheap freebie SD card reader that slots into the USB port and the 32GB card reads right up as normal. So there's something going on via maybe one of the controller chips that doesn't recognize the SDHC format. 32GB card still won't read in the built-in card slot. |
