- Added a term: file allocation table (FAT): An area on a hard disk or floppy disk where information is stored about the physical location of each piece of every file on the disk and about the location of unusable areas of the disk.Read more: http://www.answers.com/topic/file-allocation-table#ixzz1fVWnz49P
- marked the description of file allocation table (FAT) as not a spoiler
- Added a term: Cluster: Also called an "allocation unit" or "file allocation unit," it is some number of disk sectors that are treated as a unit. A cluster is the smallest unit of storage the operating system's file system can manage. That means if a 1KB file is stored in a system with a 32KB cluster (see table below), the 1KB file takes up 32KB of disk space.Read more: http://www.answers.com/topic/tone-cluster#ixzz1fVXdxLZL

- Added a term: fragmentation: The scattering of parts of a file throughout a disk, as when the operating system breaks up the file and fits it into the spaces left vacant by previously deleted files.Read more: http://www.answers.com/topic/fragmentation#ixzz1fVY9rPRY
- marked the description of fragmentation as not a spoiler
- Added a term: New Technology File System: The primary Windows file system, starting with Windows NT. NTFS is required to implement various security and administrative features in Windows. For example, NTFS supports Active Directory domain names and provides file encryption. Permissions can be set at the file level rather than by folder, and individual users can be assigned disk space quotasRead more: http://www.answers.com/topic/ntfs#ixzz1fVYXdCPw

- Added a term: dynamic disk: A Windows 2000 feature that allows a single disk reference to span more than one physical disk volume. It also allows the disk to be resized without rebooting (resized "dynamically"). When formatted as a dynamic disk, the volume does not contain partitions. A regular disk partition is called a "basic" disk.Read more: http://www.answers.com/topic/dynamic-disk#ixzz1fVTf9Ano
- marked the description of dynamic disk as not a spoiler
- Added a term: page file: In storage, a pagefile is a reserved portion of a hard disk that is used as an extension of random access memory (RAM) for data in RAM that hasn't been used recently. A pagefile can be read from the hard disk as one contiguous chunk of data and thus faster than re-reading data from many different original locations. Windows NT administrators or users can reset the system-provided default size value of the pagefile to meet their particular needs. In other operating systems, the pagefile is called a swap file or a swap partition.http://searchcio-midmarket.techtarget.com/definition/pagefile

- Added a term: Disk Management: Disk Management is an extension of the Microsoft Management Console that allows full management of the disk-based hardware recognized by Windows.Disk Management is used to manage the drives installed in a computer - like hard disk drives (internal and external), optical disk drives, and flash drives.about.com

- Added a term: partition: a portion of a computer’s hard disk that is treated by the computer as if it were a separate disk drive. A very large drive is more efficient if partitioned because the file clusters are smaller (so that small files do not waste so much space) and because the computer does not have to search as large an area for data. Communication between partitions, however, is more cumbersome. Read more: http://www.answers.com/topic/partition#ixzz1fVOMs6Rh

- Added a term: format: •To divide (a disk) into marked sectors so that it may store data.Read more: http://www.answers.com/topic/format#ixzz1fVOhSJ51
- marked the description of format as not a spoiler
- Added a term: file system: The method for storing and retrieving files on a disk. It is system software that takes commands from the operating system to read and write the disk clusters (groups of sectors). The file system manages a folder/directory structure, which provides an index to the files, and it defines the syntax used to access them (how the "path" to the file is coded). File systems dictate how files are named as well as the maximum size of a file or volume. There are numerous file systems in use; for example, FAT32 and NTFS are Windows file systems, and HFS is used on Macs. Linux uses ext2, ext3 and FAT32. Unix systems use UFS, ext2, ext3 and ZFS.Read more: http://www.answers.com/topic/file-system#ixzz1fVOzJAij

- Added a term: master boot record: is a type of boot sector popularized by the IBM Personal Computer.<1> It consists of a sequence of 512 bytes located at the first sector of a data storage device such as a hard disk. MBRs are usually placed on storage devices intended for use with IBM PC-compatible systems.The MBR may be used for one or more of the following:•Holding a partition table, which describes the partitions of a storage device. In this context the boot sector may also be called a partition sector.•Bootstrapping an operating system. The BIOS built into a PC-compatible computer loads the MBR from the storage device and passes execution to machine code instructions at the beginning of the MBR.•Uniquely identifying individual disk media, with a 32-bit disk signature, even though it may never be used by the operating system.Read more: http://www.answers.com/topic/master-boot-record#ixzz1fVQDQQGt
- marked the description of master boot record as not a spoiler
- Added a term: partition table: In DOS and Windows, it is a part of the master boot record (MBR) that describes how the disk is partitioned. The MBR reads the partition table to determine which partition is active (contains the operating system) and where its boot sector is located.Read more: http://www.answers.com/topic/partition-table-1#ixzz1fVQfZsKl

- Added a term: logical drives: A data storage unit, such as a subpartition of a hard drive or an array of storage units, recognized and handled according to the logic of the operating system like a single physical drive. --------------------------------------------------------------------------------Read more: http://www.answers.com/topic/logical-drive#ixzz1fVRIn5xU
- marked the description of logical drives as not a spoiler
- Added a term: volume boot sector: is the first sector of a data storage device that has not been partitioned, or the first sector of an individual partition on a data storage device that has been partitioned. It may contain code to load and invoke an operating system (or other standalone program) installed on that device or within that partition.Read more: http://www.answers.com/topic/boot-sector#ixzz1fVS0HPkq

- Added a term: Registry: The configuration database in all 32-bit versions of Windows that contains settings for the hardware and software in the PC it is installed in. The Registry is made up of the SYSTEM.DAT and USER.DAT files. Many settings previously stored in the WIN.INI and SYSTEM.INI files in 16-bit Windows (Windows 3.x) are in the Registry. The Registry can be edited directly, but that is usually only done for very technical enhancements or as a last resort. Routine access is done via the Control Panels in My Computer or any Properties menu. Right clicking almost every icon in Windows brings you the Properties menu for that object. A PC with many applications that has been used for a while can easily have a hundred thousand or more Registry entries. See Win Registry and Registry cleaner.Read more: http://www.answers.com/topic/registry#ixzz1fP8082Lw
