www.gateway.com 3 Click Check Now, then click Start. Your drive is checked for errors. This process may take several minutes. Important Error checking cannot scan a drive while the drive is being used. If you try to check your hard drive for errors, you see a prompt asking you if you want to scan the hard drive later (the next time you restart your computer). If you see this prompt, click Schedule disc check. After Windows has finished checking the drive for errors, it provides a summary of the problems that it found. 4 Correct any problems that are found by following the on-screen instructions. 5 Click OK. Help For more information about checking the hard drive for errors, click Start, then click Help and Support. Type checking for disk errors in the Search Help box, then press ENTER. Defragmenting the hard drive When working with files, sometimes Windows divides the file information into pieces and stores them in different places on the hard drive. This is called fragmentation, and it is normal. In order for your computer to use a file, Windows must search for the pieces of the file and put them back together. This process slows the hard drive performance. Disk Defragmenter organizes the data on the drive so each file is stored as one unit rather than as multiple pieces scattered across different areas of the drive. Defragmenting the information stored on the drive can improve hard drive performance. While Disk Defragmenter is running, do not use your keyboard or mouse because using them may continuously stop and restart the defragmenting process. Also, if you are connected to a network, log off before starting Disk Defragmenter. Network communication may stop the defragmentation process and cause it to start over. Tip Because defragmenting a drive may take hours to complete (depending on the size of the drive being defragmented), consider starting the process when you will not need the computer for several hours. 61
