what are the differences in the abilities of windows xp, vista, and 7 to resize partitions?

Creation of split up accessible storage areas on a secondary computer storage device

GParted is a popular utility used for disk sectionalisation

Disk sectionalisation or disk slicing ^[ane] is the creation of one or more than regions on secondary storage, and so that each region can be managed separately.^[2] These regions are called partitions. Information technology is typically the first step of preparing a newly installed disk, before any file system is created. The deejay stores the information about the partitions' locations and sizes in an expanse known equally the partition table that the operating organization reads before any other role of the disk. Each segmentation then appears to the operating system as a distinct "logical" disk that uses office of the bodily deejay. System administrators use a programme called a partition editor to create, resize, delete, and manipulate the partitions.^[3] Partitioning allows the apply of unlike filesystems to be installed for dissimilar kinds of files. Separating user data from organization data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier. A disadvantage is that information technology can be difficult to properly size partitions, resulting in having one partition with too much complimentary infinite and another nearly totally allocated.

History [edit]

IBM in its 1983 release of PC DOS version two.0 was an early if not beginning use of the term partition to depict dividing a block storage device such as an HDD into concrete segments. The term's usage is now ubiquitous. Other terms used in the fine art have included logical deejay,^[iv] minidisk,^[5] portions,^[half-dozen] pseudo-disk,^[6] section,^[6] slice ^[7] and virtual drive.^[eight]

I of the earliest such segmentation of a disk drive was IBM'due south 1966^[9] usage in its CP-67 operating arrangement of minidisk as a carve up segment of a hard disk.^[5]

Segmentation schemes [edit]

DOS, Windows, and OS/2 [edit]

With DOS, Microsoft Windows, and OS/2, a common practice is to use i principal partition for the active file organization that volition contain the operating organisation, the page/bandy file, all utilities, applications, and user data. On virtually Windows consumer computers, the drive alphabetic character C: is routinely assigned to this main division. Other partitions may exist on the HDD that may or may not be visible every bit drives, such as recovery partitions or partitions with diagnostic tools or data. (Windows drive messages do not correspond to partitions in a one-to-i fashion, then there may be more or fewer bulldoze messages than partitions.)

Microsoft Windows 2000, XP, Vista, and Windows 7 include a 'Disk Management' plan which allows for the cosmos, deletion and resizing of FAT and NTFS partitions. The Windows Disk Manager in Windows Vista and Windows vii utilizes a one MB partition alignment scheme which is fundamentally incompatible with Windows 2000, XP, OS/2, DOS likewise as many other operating systems.

Unix-like systems [edit]

On Unix-based and Unix-like operating systems such as Linux, macOS, BSD, and Solaris, it is possible to use multiple partitions on a disk device. Each partition tin be formatted with a file system or as a bandy segmentation.

Multiple partitions allow directories such equally /boot, /tmp, /usr, /var, or /home to be allocated their own filesystems. Such a scheme has a number of advantages:

• If one file arrangement gets corrupted, the data outside that filesystem/partition may stay intact, minimizing data loss.
• Specific file systems tin be mounted with unlike parameters, due east.one thousand., read-merely, or with the execution of setuid files disabled.
• A runaway program that uses up all available space on a not-organization filesystem does non fill upwardly critical filesystems.
• Keeping user data such as documents carve up from organisation files allows the system to be updated with lessened risk of agonizing the data.

A common minimal configuration for Linux systems is to use three partitions: one holding the arrangement files mounted on "/" (the root directory), ane holding user configuration files and data mounted on /habitation (home directory), and a bandy division.

By default, macOS systems also apply a single partition for the entire filesystem and utilise a swap file inside the file arrangement (similar Windows) rather than a swap partition.

In Solaris, partitions are sometimes known as slices. This is a conceptual reference to the slicing of a cake into several pieces.

The term "slice" is used in the FreeBSD operating organization to refer to Chief Kick Record partitions, to avoid defoliation with FreeBSD'southward own disklabel-based partitioning scheme. Yet, GUID Partition Table partitions are referred to every bit "partition" worldwide.

Multi-kicking systems [edit]

Multi-boot systems are computers where the user can kicking into more than than one singled-out operating system (OS) stored in separate storage devices or in carve up partitions of the same storage device. In such systems a bill of fare at startup gives a choice of which Os to boot/start (and just one Os at a time is loaded).

This is distinct from virtual operating systems, in which one operating system is run equally a self-contained virtual "program" within another already-running operating system. (An instance is a Windows OS "virtual machine" running from within a Linux OS.)

GUID Partition Table [edit]

The GUID Partition Table (Grandlobally Unique IDentifier) is a office of the Unified Extensible Firmware Interface (UEFI) standard for the layout of the partition table on a physical hard disk drive. Many operating systems now support this standard. Notwithstanding, Windows doesn't support this on BIOS based computers.^[10]

Partition recovery [edit]

When a partition is deleted, its entry is removed from a table and the data is no longer attainable. The data remains on the disk until being overwritten. Specialized recovery utilities may be able to locate lost file systems and recreate a partition table which includes entries for these recovered file systems. Some disk utilities may overwrite a number of beginning sectors of a partitioning they delete. For example, if Windows Deejay Management (Windows 2000/XP, etc.) is used to delete a partition, it will overwrite the starting time sector (relative sector 0) of the sectionalisation earlier removing information technology. Information technology still may be possible to restore a FAT or NTFS partition if a backup kicking sector is bachelor.

Compressed disks [edit]

HDDs can be compressed to create additional space. In DOS and early Microsoft Windows, programs such every bit Stacker (DR-DOS except 6.0), SuperStor (DR DOS vi.0), DoubleSpace (MS-DOS half dozen.0–6.two), or DriveSpace (MS-DOS 6.22, Windows 9x) were used. This compression was washed by creating a very large file on the partition, then storing the disk's data in this file. At startup, device drivers opened this file and assigned information technology a split letter of the alphabet. Oft, to avert defoliation, the original partition and the compressed bulldoze had their messages swapped, then that the compressed disk is C:, and the uncompressed area (ofttimes containing system files) is given a higher name.

Versions of Windows using the NT kernel, including the most contempo version, Windows 10, contain intrinsic deejay compression capability. The apply of split disk compression utilities has declined sharply.

Partitioning tabular array [edit]

A partition table is a table maintained on a deejay by the operating system that outlines and describes the partitions on that disk.^[11] The terms partition table and sectionalization map are similar terms and tin can used interchangeably. The term is most ordinarily associated with the MBR partition table of a Master Boot Tape (MBR) in PCs, simply it may be used generically to refer to other formats that dissever a deejay drive into partitions, such as: GUID Partition Tabular array (GPT), Apple partition map (APM),^[12] or BSD disklabel.^[13]

PC partition types [edit]

MBR [edit]

This department describes the master kicking record (MBR) partitioning scheme, as used historically in DOS, Microsoft Windows and Linux (among others) on PC-compatible calculator systems. As of the mid-2010s, most new computers use the GUID Sectionalisation Table (GPT) partitioning scheme instead. For examples of other partition schemes, see the general article on segmentation tables.

The full data storage infinite of a PC HDD on which MBR partitioning is implemented can contain at about four master partitions, or alternatively three primary partitions and an extended partition. The Partition Table, located in the main boot record, contains 16-byte entries, each of which describes a partition.

The partition type is identified by a one-byte code found in its partition table entry. Some of these codes (such as 0x05 and 0x0F) may be used to signal the presence of an extended sectionalisation. Most are used by an operating arrangement's bootloader (that examines partition tables) to decide if a sectionalization contains a file system that tin can be mounted / accessed for reading or writing information.

Master partition [edit]

A main sectionalization contains one file system. In DOS and all early versions of Microsoft Windows systems, Microsoft required what it called the organization partitioning to be the first partition. All Windows operating systems from Windows 95 onwards can be located on (most) any partition, merely the boot files (io.sys, bootmgr, ntldr, etc.) must reside on a primary partition. Even so, other factors, such every bit a PC's BIOS (see Boot sequence on standard PC) may also impose specific requirements as to which partition must contain the master OS.

The partition type code for a main sectionalisation can either represent to a file system contained within (e.1000., 0x07 ways either an NTFS or an OS/ii HPFS file system) or indicate that the partition has a special use (e.g., code 0x82 usually indicates a Linux bandy partition). The FAT16 and FAT32 file systems accept fabricated utilize of a number of partition type codes due to the limits of diverse DOS and Windows Bone versions. Though a Linux operating organisation may recognize a number of different file systems (ext4, ext3, ext2, ReiserFS, etc.), they have all consistently used the same partition blazon code: 0x83 (Linux native file organisation).

Extended sectionalization [edit]

An HDD may contain but i extended partition, just that extended division can be subdivided into multiple logical partitions. DOS/Windows systems may then assign a unique drive letter to each logical sectionalization. GUID partition table (GPT) just has the main partition, doesn't have the extended partition and the logical sectionalisation.

Boot partitions [edit]

BIOS boot partition [edit]

BIOS kicking sectionalization (BIOS BP) is a share of the storage device used to keep software that boots the operating organization, a bootloader. It may be an operating organisation kernel image or bootloader or a completely separate piece of software.^{[14] [fifteen] : 136}

EFI system partition [edit]

EFI system segmentation is the same equally BIOS BP, but is loaded by EFI firmware instead of BIOS.^{[xiv] [15] : 136}
