- Disk management tools
New data and files are generally written to the first available space on a disk drive. Over time, files are changed, re-wriiten, or deleted, and open up new areas of available disk space. This open space may in turn be used by another application or file for storage creating a scattered, or fragmented structure to related data. This creates a situation where the disk heads are required to increase travel for reading and writing data and efficiency suffers.
The DEFRAG utility is used to analyze the fragmentation of files and folders on local drives and reconstruct the data into contiguous order.

NTBACKUP is a built-in backup application introduced in Windows NT and included with Windows 2000, Windows XP Pro, Windows 8, as well as Windows Server versions 2003, 2008, and 2012. NTBACKUP is not installed by default in XP Home Edition.
How To Use The Backup Utility In Windows XP
How to install NTBACKUP on Windows XP Home
Manually Edit Ntbackup.exe Selection Script Files
The ntbackup command is not available in Windows Vista or Windows Server 2008. Instead, you should use the wbadmin command and subcommands to back up and restore your computer and files from a command prompt.
You cannot recover backups that you created with ntbackup by using wbadmin. However, a version of ntbackup is available as a download for Windows Server 2008 and Windows Vista users who want to recover backups that they created using ntbackup. This downloadable version of ntbackup enables you to perform recoveries only of legacy backups, and it cannot be used on computers running Windows Server 2008 or Windows Vista to create new backups. To download this version of ntbackup, see Windows NT Backup - Restore Utility.
- Check Disk
The chkdsk or “Check Disk” utility is used in Windows to locate and repair logical file system errors or check the disk surface for physical errors and bad sectors.
- /f : Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.
- /r : Locates bad sectors and recovers readable information. The disk must be locked.

- Active, primary, extended and logical partitions
There are two types of partitions, primary and extended. A primary partition is one into which you can install the files needed to load an operating system. A primary partition is formatted for a particular file system and is assigned a drive letter. Having multiple primary partitions enables you to install and start operating systems that do not use the same file system. You can have as many as four primary partitions on a hard disk.
You can have one extended partition on a hard disk. An extended partition is effectively a logical disk. Unlike a primary partition, you do not format the extended partition, nor does it get assigned a drive letter. Instead, you can create one or more logical drives within the extended partition, and each logical drive is assigned a drive letter. You format each logical drive for a particular file system. An extended partition is a method for configuring a hard disk into more than four logical areas. If you have an extended partition on the disk, you can have up to three primary partitions.

- FAT32 and NTFS
The FAT file system is a better choice than NTFS for volumes that are smaller than approximately 400-500 MB, because of the amount of disk space overhead involved in NTFS, but is very inefficient for volumes larger than 1 gigabyte (GB). This overhead is in the form of NTFS system files and the log file, which can use a large percentage of the total disk space on a small volume.
Windows 95 OSR2, Windows 98, Windows 2000, and Windows Me are the only Microsoft operating systems that can access FAT32 volumes.
The NTFS file system is best for use on volumes of about 400 MB or more, because performance does not degrade as much on larger NTFS volumes as compared to larger FAT volumes. However, if you want to use features that are available only on NTFS, such as file security or compression, you can use NTFS on smaller volumes.
NTFS is a proprietary file system for Windows XP, Vista, NT, and Windows 7.
