SDHC card locked?

[Bruce Labitt]

I recently bought a Flash Air III SDHC card.   I wanted to copy my data 
from another SDHC card to it.  The card seems to be locked, and is 
preventing writing to the card - although the little slider is set to 
the unlocked position.  Short of returning the card, which may be my 
best option, what can I do to check that the card is actually ok, or my 
laptop's SD card reader is at fault.

I checked the properties of the card - it is set to user - 
read/write/execute

$ getfacl /media/bruce/647E-E27B2

Thanks,
