Make sure you are root when using gparted.  A couple more things:  After
you plug in the card, check the last few lines from the "dmesg" command. 
Linux may change it to read only if it encounters errors from the device.

Also try running "mount" with no arguments.  It should show you if the
device is mounted read only (ro)
