Sharing Memory Cards
If you plan to share your memory card between your VAIO ® computer and devices such as a digital camera or music player,
the card must be formatted properly.
 Format the memory card by using it in the device first. See the information supplied with the device for details how
to format the memory card.
 If your device does not recognize memory card that has been formatted by your computer, follow these steps:
1. Save the card's contents to your hard disk drive.
2. Reformat the memory card using the device, not your computer.
