Maintaining Disks, Partitions, and Volumes tutorials

In this lesson we will discuss about

  • What is Disk Fragmentation.

  • Defragmenting a disk

  • Disk Quotas.


Disk Fragmentation

  • When you create a volume, Format It and then start using it by creating new files, folders & sub-folders on the available free space, Initially data written and maintained in contiguous blocks.

  • As you use disk for Creating new files, Modifing it, Deleting contineously, fragmentation of file system occurs. Similarly as volume fills up with data and other files, contiguous area of free space reduces. This forces the Hard-disk to save remainder of files in non-contiguous area.

  • While referring those fragmented files, Hard-disk Read/Write head have to shift head position from one sector to another sector - leading into performance delay. Although NTFS file system is more efficient at handling disk fragmentation than earlier file systems, this fragmentation still causes performance problem.

  • Window helps in reducing impact of Disk Fragmentation. It optimize volume and rearranges fragemented data in optimal method by joining fragmented files.


Exercise : Disk Defragmentation

  1. Press Windows Key and E, it opens Computer, Select Disk Drive you want to Defragment, Right Click - Properties, Select Tool and click Optimize button.

  2. To verify that a disk requires defragmentation, select the disk partition you want to defragment and then click Analyse option. If the number is high, defragment the disk.

  3. You also can schedule disk-defragmentation. By default Schedule Defragmentation is on. It perform it weekly, you can change it to Daily, Weekly or monthly.

  4. You can also get notification if three consecutive scheduled run are missed.

  5. NOTE :- Defragmentation of disk may take from several minutes to few hours.
