File, Drive, and PC Card Problems

For information about compatible cards, visit our Web site at

• Try removing and reinserting the card.

Try inserting the card in the other card slot to check the connector.
• Try removing a PC card from the other card slot, if another card is present.
• For a data storage card, check that you’re using the correct drive letter.
