Improving hard drive performance

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.
