SD card reader problem

Hoping for some help with this one... I have a mid-2009 13" MBP (2.26, 4 gigs, 1TB HDD, SL 10.6.4) and the SD card reader is not recognizing any of my SD cards (won't mount and also not seen in Disk Utility). The cards are recognized when using a USB adaptor, and also work fine in my wife's MBP SD card reader, so I know it's not the cards. System Profiler recognizes the internal card reader on my system:

Copied from Apple System Profiler:

USB High-Speed Bus:

Host Controller Location: Built-in USB
Host Controller Driver: AppleUSBEHCI
PCI Device ID: 0x0aa9
PCI Revision ID: 0x00b1
PCI Vendor ID: 0x10de
Bus Number: 0x26

Internal Memory Card Reader:

Product ID: 0x8403
Vendor ID: 0x05ac (Apple Inc.)
Version: 98.33
Serial Number: 000000009833
Speed: Up to 480 Mb/sec
Manufacturer: Apple
Location ID: 0x26500000
Current Available (mA): 500
Current Required (mA): 500

Also, the card reader is recognized in Windows, but still doesn't detect the card when inserted.

This one has me stumped, so any help is very much appreciated.

MBP, Mac OS X (10.6.4)

SOLUTION WITH CONTACT CLEANER


Hi.


I also had this problem with my MacBook. I tried compressed air and twisting the card, but nothing work. I finaly gave it a good soak of some good contact cleaner, and BINGO! it finaly brought my sd-card reader back to life. I noticed that if i press the card fully in, it not work.

I had successfully repaired my SD card reading problem.

There are a few possibilities:


1. Card contact point or dust issue.

- This is unlikely to happen with your new MBP and the contact point for newer MBP is pretty tight.


2. Broken SD card adapter

- Make sure you use a descent adapter.


3. Still connected with your VM

- For example: VirtualBox VM, make sure you:

- disconnect any USB device in VM and shut down properly.

- unmount any virtual disk in virtual machine.

- in Setting > Ports > USB > Enable USB 2.0 (EHCI) Controller, uncheck it.


4. Nothing happened with the step you tried?

- quit VM entirely and open Utility > Console.app

- see the log file and troubleshoot any irregularities.


5. Repeat step 1 - 4.

I have only had this problem for 2 days, thought it might be a software issue but tried all the solutions suggested on here, the only one that worked for me was cleaning out the SD card reader as best I could with compressed air, and then putting the card in gently (not forced in all the way)


Hopefully this solves it for someone else too!

Similar to other suggestions on here, the mechanical solution worked for me. I hadn't been able to get my Mac to read any SD cards in months, and all the terminal and safe boot suggestions hadn't worked. So finally I folded up a piece of card and pushed that in there a few times, combined with lots of blowing air into the slot, and finally pushing on the little switches with the end of a paper clip. Success!

Incredible! it works!, it didn‘t work the first time, but then from the secnd try it started working.


In the past it used to work normally, it doesn't anymore.


Even after having success with this trick, if I put it normally it still doesn't work.


The moral of the storyis that raw force does solve issues some times! 😝


Thank you Docsilo for sharing your solution!
