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.

To run Disk Defragmenter:

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

2.Click Defragment now.

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 Windows 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 ProtectSmart Hard Drive Protection

HP ProtectSmart Hard Drive Protection 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 ProtectSmart Hard Drive Protection returns the hard drive to normal operation.

NOTE: Because solid-state drives (SSDs) lack moving parts, HP ProtectSmart Hard Drive Protection is unnecessary.

NOTE: Hard drives connected to USB ports are not protected by HP ProtectSmart Hard Drive Protection.

For more information, refer to the HP ProtectSmart Hard Drive Protection software Help.
