I'm trying to write to an sd card which I formatted in my nook color but can't get beyond permissions denied. I formated the card in the nook and also erased all data but when I access it via disk utility on the mac every option like to reformat or erase is greyed out. When I try to burn the data via the command line with dd it shows it as a read only device.

I guess my question is how to change it to read/write....

    You checked that the write-protect switch on the card isn't set, right?

    I have experienced this exact problem, while trying to burn a disc image to sd for my Nook on my Macbook OSX 10.6.8. The funny thing is that I had preformed this same operation 6 months ago and it worked perfectly. Now I get the permission denied error, and every card I've plugged into my usb card reader, registers read only in Disk Utility. There must be something in an update, that is now preventing me from writing to sd cards.

    This needs to be addressed or I will have to bail on Apple. FAIL

    Had this issue just now and the write-protect switch on the card was OFF. But somehow the switch must've been stuck or something: I inserted the card a few times into the slot, it always appeared as "read-only" to the machine. Setting the write-protect switch to ON and then OFF again did not help - I had to  repeat this a few times until the card was finally recognized as read-write. So, SD-Card FAIL, the OS wasn't the issue in my case.
