Defragmentation can improve data access performance for HDDs that store information on disk platters, whereas it can cause SSDs that use flash memory to wear out faster.
The term defragment refers to rearranging file segments on a storage device in contiguous order so the file is no longer fragmented. Fragmentation makes your computer work harder and perform slower. When a computer saves a file to a hard drive, it uses whatever space is available -- if there is not enough consecutive free space to hold the file as a whole, the hard drive splits the file into multiple parts and store those parts in available open spaces.
A non-contiguous file is called a fragmented file. If your computer's running slower than normal, you might be able to speed things back up by defragmenting that hard drive. Defragmenting is beneficial for HDDs because it brings files together instead of scattering them so that the device's read-write head doesn't have to move around as much when accessing files.
Two things affect how quickly a hard drive recalls data: seek time and read speed which relate to the time it takes to move the controller arm to the data location and how long it takes to read the data. Defragmenting improves load times by reducing how frequently the hard drive has to seek data. Removable storage devices such as USB flash drives can also become fragmented.
Disk Defragmenter in Windows rearranges fragmented data so your disks and drives can work more efficiently. Disk Defragmenter runs on a schedule, but you can also analyze and defragment your disks and drives manually. To do this, follow these steps:.
Open Disk Defragmenter by clicking the Start button. In the search box, type Disk Defragmenter , and then, in the list of results, click Disk Defragmenter. To determine if the disk needs to be defragmented or not, click Analyze disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Run column. Click Defragment disk. Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk.
You can still use your computer during the defragmentation process. If a disk that you're expecting to see under Current status is not showing up there, it might be because it contains an error. Try to repair the disk first, then return to Disk Defragmenter to try again.
