1 Identifying installed drives

On models with a secondary hard drive (drive D), the optical drive becomes drive E. The next drive
added to the system, such as a new USB drive, will be assigned the next available drive letter.

2 Handling drives
Drives are fragile computer components that must be handled with care. Refer to the following cautions
before handling drives. Additional cautions are included with the procedures to which they apply.
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 or external hard drive from one location to another, initiate Sleep,
and allow the screen to clear.
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 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 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
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.
