How to Defrag a Network Driveby Garrett Genet
Regularly defragmenting your hard drives keeps them in top working condition. A hard drive becomes fragmented when over the course of time the information stored on it becomes scattered throughout the disk. When you defragment a drive, you rearrange the drive so that all files relating to a specific task or program are located close together; this prevents the system from having to scan the entire disk for the data it needs.
Log into the computer sharing the drive.
Open your "Start" menu and select "All Programs."
Click "Accessories" then "System Tools."
Click "Disk Defragmenter."
Select the network drive and click "Defragment disks."
