Back up your information. 2. Remove all optical discs and all external media cards, such as digital cards and ExpressCards. Ä To reduce the risk of damage to the computer, damage to a drive, or loss of information, remove the media from a drive before removing the drive from a drive bay, and before shipping, storing, or traveling with a drive. 3. Turn off and then disconnect all external devices. 4. Shut down the computer. ■ Take along a backup of your information. Keep the backup separate from the computer. ■ When traveling by air, carry the computer as hand luggage, and do not check it in with the rest of your bags. Ä CAUTION: Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walk-through devices and security wands. The airport security devices that check carry-on luggage, such as conveyor belts, use X-rays instead of magnetism and will not damage a drive. 10 Getting Started
