Handling drives
CAUTION:Drives are fragile computer components that must be handled with care. see the
following cautions before handling drives. Additional cautions are included with the procedures to
which they apply.
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 an 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.

							Using hard drives
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.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
After you start Disk Defragmenter, it works without supervision. Depending on the size of your hard
drive and the number of fragmented files, Disk Defragmenter may take more than an hour to
complete. You may want to set it to run during the night or at another time when you do not need
access to your computer.
HP recommends defragmenting your hard drive at least once a month. You may set Disk
Defragmenter to run on a monthly schedule, but you can defragment your computer manually at any
time.
