Memory card appears in My Computer, but errors occur when writing or reading.

Cause

Solution

You are using an adapter for a type of memory card not supported by the reader.

Consult the manufacturer of the adapter for help. Be sure that the memory card is one of the supported types: CompactFlash (1, 2, and Microdrive), Memory Stick, MultiMedia, Secure Digital, or SmartMedia memory cards.

The memory card is not properly inserted.

Make sure that the memory card is fully inserted into the slot.

The internal memory card reader pin is bent.

Shine a flashlight into the empty card slots. Check whether any pins inside are bent. Disconnect the computer from power and straighten the bent pins with the end of a mechanical pencil. If a pin has bent to the point where it is touching another pin, replace the memory card reader or have the computer serviced.
