Author Info Last Updated: April 28, Understanding Defragmentation. Know why a hard drive gets fragmented.
When a hard drive is freshly formatted, the system files are located at the beginning of the drive, and the rest is a large block of free space. This space is optimally filled as new data is added to the drive. As files are altered, deleted, and moved around the hard drive, pieces of data and small blocks of free space get left behind. Learn how fragmentation affects performance. As the amount of fragments increase in the drive, performance starts to deteriorate.
The drive will take longer to find files, and free space on the drive will be misreported. Know how to prevent fragmentation. Many modern file systems are built to limit the amount of fragmentation that occurs. Solid state drives flash memory do not require defragmentation, as there is no mechanical read mechanism.
Defragmenting a solid state drive will actually cause it to fail sooner, because data can only be written a certain number of times. Method 1. Open the Disk Defragmenter utility. Select Disk Defragmenter from the list. You will need to have administrator access to run the Disk Defragment utility. You can also open the Disk Defragmenter utility by clicking Start then Search. Select your drive. There will be a list of drives that are attached to your computer. Select the drive that you would like to defragment.
This is typically the C: or D: drive. Click the Analyze button to see if the drive needs to be defragmented. Thank you! Any more feedback? The more you tell us the more we can help.
