i insert my card reader on the comp then when i click it on my computer it says i need to format it then when i click okay it says that WINDOWS UNABLE TO FORMAT.what should i do?
Is the card that is inserted locked? Most SD cards have a safety lock so that you can't remove anything from them accidentally. Try taking it out of the reader, and look for a small switch on one side. This can be moved up or down. On one end it might say lock. This is a very, very small switch, and it is somewhat hard to describe! Sorry Hope that helps!
