CAUTION: To reduce the risk of damage to the computer, damage to a drive, or loss of information, observe these precautions: Before you move a computer that is connected to an external hard drive, initiate Sleep and allow the screen to clear, or properly disconnect the external hard drive. Before handling a drive, discharge static electricity by touching the unpainted metal surface of the drive. Do not touch the connector pins on a removable drive or on the computer. Handle a drive carefully; do not drop a drive or place items on it. Before removing or inserting a drive, shut down the computer. If you are unsure whether the computer is off, in the Sleep state, or in Hibernation, turn the computer on and then shut it down through the operating system. Do not use excessive force when inserting a drive into a drive bay. Do not type on the keyboard or move the computer while the optical drive (select models only) is writing to a disc. The write process is sensitive to vibration. When the battery is the only source of power, be sure that the battery is sufficiently charged before writing to media. Avoid exposing a drive to temperature or humidity extremes. Avoid exposing a drive to liquids. Do not spray the drive with cleaning products. Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping, or storing a drive. If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package "FRAGILE." Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walkthrough devices and security wands. The airport security devices that check carry-on luggage, such as conveyor belts, use X-rays instead of magnetism and does not damage a drive. Improving hard drive performance Using Disk Defragmenter As you use the computer, files on the hard drive become fragmented. Disk Defragmenter consolidates the fragmented files and folders on the hard drive so that the system can run more efficiently. To run Disk Defragmenter: 1. Select Start > All Programs > Accessories > System Tools > Disk Defragmenter. 2. Click Defragment now. NOTE: Windows® includes the User Account Control feature to improve the security of your computer. You may be prompted for your permission or password for tasks such as installing applications, running utilities, or changing Windows settings. Refer to Help and Support for more information. For additional information, access the Disk Defragmenter software Help. Using Disk Cleanup Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk space and help the computer to run more efficiently. Drives 55
