Using HP 3D DriveGuard

HP 3D DriveGuard protects a hard drive by parking the drive and halting data 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: Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary.

NOTE: Hard drives in the primary hard drive bay or in the secondary hard drive bay are protected by HP 3D DriveGuard. Hard drives connected to USB ports are not covered by HP 3D DriveGuard.

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

Using Disk Defragmenter

As you use your computer over time, the files on the hard drive become fragmented. A fragmented drive means data on your drive is not contiguous (sequential) and, because of this, the hard drive works harder to locate files, thus slowing down the computer. Disk Defragmenter consolidates (or physically reorganizes) 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. However, depending on the size of your hard drive and the number of fragmented files, Disk Defragmenter may take more than an hour to complete.

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.

To run Disk Defragmenter:

1.Connect the computer to AC power.

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

3.Follow the on-screen instructions.

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 run more efficiently.

To run Disk Cleanup:

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

2.Follow the on-screen instructions.
