• Make sure the card reader has been properly connected to a USB
connector on your computer' s system board.
• Try a different memory card of the same type in the same slot. If the
different memory card works, the card reader is functioning and the
original memory card is damaged or defective and should be replaced.
• Shine a flashlight into the empty card slots. Look to see if any of the pins
inside the slots are bent. If so, turn off and unplug your computer, then
straighten bent pins with the tip of a mechanical pencil or safety pin.
Replace the memory card reader if a pin has been bent to the point of
touching another pin.
• Make sure the memory card is fully inserted into the appropriate card slot
on the reader.
• Try a different memory card of the same type in the same slot. If the
different memory card works, the card reader is functioning and the
original memory card is damaged or defective and should be replaced.
• Some cards have a read/write security switch on them. Make sure that
this switch is not in the lock position before attempting to write data to
the card.
• Make sure that the amount of data you are attempting to write to the
card does not exceed the amount of available free space on the card.
• Inspect the ends of the memory card for dirt and dust, which may be
covering a metal contact. Clean the contacts with a lint-free cloth and
small amounts of isopropyl alcohol. Replace the memory card if
necessary.
• If errors persist, replace the memory card.
