Currently Being ModeratedOct 18, 2010 7:33 PM (in response to sig)You missed the part of my post that reads, *"None of the cards are locked."*
However, I have found a solution, and it seems the problem is the SD card slot itself.
On all the SD cards, if I keep the lock slider in between Locked and Unlocked, the computer will see it as read/write. If it's fully at unlocked, it'll be read only.
Locked ___:-:___ Unlocked
Kinda odd. But upon searching deeper, I'm not the only one with this issue. I'll call Apple and have them fix it.

Currently Being ModeratedOct 28, 2010 7:46 PM (in response to skatalite13)skatalite13, have you found an permanent/satisfying resolution to this issue? I'm having the same problem now with both my MacBook and my iMac.

Currently Being ModeratedDec 10, 2010 12:52 PM (in response to skatalite13)Unbelievable.. I don't have a built-in SD slot, but this turned out to be the same problem for me.. more or less.
Only difference is I had my SD card in a USB SD card reader.
The SD card was:
- read-only with the SD card switch locked (duh!)
- read-only with the SD card switch unlocked
- unrecognised by my Mac with the SD card switch half-way
- read/write (TADA!) with the SD card switch nudged a micrometer towards the unlocked position
So I guess some SD card reading hardware is just dodgy and you gotta try different positions of the card's locked/unlocked switch if it's telling you it's read-only!MacBook5,1, Mac OS X (10.6.5)

I had the same problem.
Fiddling with the little metal switch inside the reader with a needle a little fixed it.MacBook Pro 13", Mac OS X (10.6.6)
Currently Being ModeratedFeb 12, 2011 10:26 AM (in response to skatalite13)What worked for me is moving the switch to lock on the sd card, putting it in my reader, ejecting it, moving the switch back to unlock, putting it in the reader. After I did that I had read/write access again. This was on a 2010 macbook pro i7 15 with the internal reader.Mac OS X (10.6.6), iMac iPhone

Tried what Mike said and it worked. Have no idea why but thanks! This was on a late 2009 Macbook Pro 2.8GHz with 10.6.7.

After ejecting it and putting it back in.. wen't back to read only. Unbelievable.

I'll be calling AppleCare sometime this week. I have two SD cards, Sandisk 2GB, one's black and one is blue.
The blue one will work with the switch in the middle, the black won't. The blue one worked with the switch in the middle through 5 ejects, then with the switch in unlocked worked, but after ejecting and remounting it was locked again.
The cards both work no problem in my parent's HP desktops built in reader. This laptop is "old" by industry standards but it was $$$$$ and I just bought an iPad a couple weeks ago. I feel like I own a Xoom =(

Weirdest thing ever. Put my sd card lock switch between lock and unlock and BANG...

I am having a similar but different problem and would appreciate if you guys can chime in on mine..
I opened a new thread:
But in my case, all SD cards, both methods of connection tested (via card reader or camera connected to USB) lead to read-only SD card, making me believe there is a problem with my MBP (I have not been able to test on another computer)

I had the same result; I took a needle and bent the last 0.5mm about 90° and was able to hook it around the back of the metal pressure switch on the left side of the inside of the slot, allowing me to pull it out lightly just a bit. This worked, where compressed air and brushes didn't. Be gentle, and turn off the machine while you do this, just in case you accidentally cross the "reading/power" contacts inside there!
