Fragmentation makes your hard
disk do extra work that can slow down your computer. Removable storage
devices such as USB
flash drives can also become fragmented. Disk Defragmenter 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:
Under Current status, select the disk you
want to defragment.
To determine if the disk needs to be defragmented or not, click
Analyze disk. If you are
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. If the number is above 10%, you
should defragment the disk.
Click Defragment disk. If you are
prompted for an administrator password or confirmation, type the password or
provide confirmation.
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.
Notes
If the disk is already in exclusive use by another program, or if
the disk is formatted using a file system other than NTFS
file system, FAT, or FAT32,
it can't be defragmented.
Network locations can't be defragmented.
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. You should try to repair the disk first, then return to Disk
Defragmenter to try again. See Check your hard
disk for errors for more information.
