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.

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 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.

NOTE: It is not necessary to run Disk Defragmenter on solid-state drives.

To run Disk Defragmenter:

1. Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.

2. Click Defragment disk.

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

software, 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.

To run Disk Cleanup:

1. Select Start > All Programs > Accessories > System Tools > Disk Cleanup.

2. Follow the on-screen instructions.

Using HP 3D DriveGuard

HP 3D DriveGuard protects the hard drive by parking the drive and halting I/O requests under either of

the following conditions:

●

You drop the computer.

●

You move the computer with the display closed while the computer is running on battery power.

A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal

operation.

NOTE: Solid-state drives lack rotating parts, so protection by HP 3D DriveGuard is unnecessary.

NOTE: If the upgrade bay contains a hard drive, the hard drive is protected by HP 3D DriveGuard.

Hard drives installed in optional docking devices or connected to USB ports are not protected by HP 3D

DriveGuard.

For more information, refer to the HP 3D DriveGuard software Help.
