Handling drives
CAUTION: Drives are fragile computer components that must be handled with care. Refer to the following
cautions before handling drives. Do not drop a drive, place items on it, or expose it to liquids, or temperature
or humidity extremes.
Observe these precautions when handling drives:
● Before removing or installing 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.
● Before handling a drive, discharge static electricity by touching a grounded surface.
● Do not touch the connector pins on a removable drive or on the computer.
● Do not use excessive force when inserting a drive into a drive bay.
● 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. Airport conveyer belts and similar security devices that check
carry-on baggage use X-rays instead of magnetism and do not damage drives.
● Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping, or
storing a drive.
● Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The write
process is sensitive to vibration.
● 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.
Using hard drives
CAUTION: To prevent information loss or an unresponsive system:
Save your work and shut down the computer before adding or replacing a memory module or hard drive.
If you are not sure whether the computer is off, turn the computer on by pressing the power button. Then
shut down the computer through the operating system.
Intel Smart Response Technology (select models only)
Intel® Smart Response Technology (SRT) is an Intel® Rapid Storage Technology (RST) caching feature that
significantly enhances computer system performance. SRT allows computers with an SSD mSATA module to
be used as cache memory between the system memory and hard disk drive. This provides the advantage of
having a hard disk drive (or a RAID volume) for maximum storage capacity while simultaneously delivering
SSD enhanced system performance experience.
If you add or upgrade a hard drive and intend to set a RAID volume, you must temporarily disable SRT, set the
RAID volume, and then enable SRT. To temporarily disable SRT:
