| available disks | 使用可能なディスク (A storage pool that exposes physical disks that are currently available for inclusion in a storage pool on a particular storage subsystem) |
| basic disk | ベーシック ディスク (A physical disk that can be accessed by MS-DOS and all Windows-based operating systems. Basic disks can contain up to four primary partitions, or three primary partitions and an extended partition with multiple logical drives) |
| boot disk | ブート ディスク (A floppy disk that contains key system files from a PC-compatible operating system that can boot, or start, the PC. A boot disk must be inserted in the primary floppy disk drive (usually drive A:) and is used when there is some problem with starting the PC from the hard disk, from which the computer generally boots) |
| cluster disk resource | クラスター ディスク リソース (A disk on a cluster storage device) |
| digital video disk | デジタル ビデオ ディスク (A form of storage characterized by high capacity (roughly 650 MB) and the use of laser optics rather than magnetic means for reading data. Optical disk storage commonly used for audio, video, and computer data. DVDs range in capacity from 4.7 GB to 17 GB, and can store significantly more than a CD-ROM) |
| disk access time | ディスク アクセス タイム (The time needed for a read/write head in a disk drive to locate a track on a disk. Access time is usually measured in milliseconds and is used as a performance measure for hard disks and CD-ROM drives) |
| disk-based web site | ディスクベース Web サイト (A web site hosted on a local computer) |
| disk bottleneck | ディスクのボトルネック (A condition that occurs when disk performance is reduced to the extent that overall system performance is affected) |
| disk cache | ディスク キャッシュ (A portion of a computer's random access memory (RAM) set aside for temporarily holding information read from disk. A disk cache does not hold entire files, as does a RAM disk (a portion of memory that acts as if it were a disk drive). Instead, a disk cache is used to hold information that either has recently been requested from disk or has previously been written to disk. If the required information remains in a disk cache, access time is considerably faster than if the program must wait for the disk drive mechanism to fetch the information from disk) |
| disk configuration information | ディスク構成情報 (Information in the Windows registry on assigned drive letters, simple volumes, striped volumes, mirrored volumes, spanned volumes, and RAID-5 volumes. You can change the disk configuration by using Disk Management) |
| disk controller | ディスク コントローラー (A special-purpose chip and associated circuitry that directs and controls reading from and writing to a computer's disk drive. A disk controller handles such tasks as positioning the read/write head, mediating between the drive and the microprocessor, and controlling the transfer of information to and from memory. Disk controllers are used with floppy disk drives and hard disks and can either be built into the system or be part of a card that plugs into an expansion slot) |
| disk drive | ディスク ドライブ (A hardware device that reads data from and writes data to floppy disks) |
| disk duplication | ディスク複製 (The process of using third-party hardware or software to copy a full master Windows installation onto the hard disks of multiple destination computers. The master computer and destination computers must have compatible hardware abstraction layers (HALs). The destination computer can be delivered directly to customers, or it might require additional processing on the factory production line) |
| disk extent | ディスク拡張 (A contiguous run of sectors on one disk) |
| disk partition | ディスク パーティション (A section of space on a physical disk that functions as if it were a separate disk) |
| disk space | ディスク領域 (The amount of data that can be stored on a disk, usually measured in bytes) |
| double-density disk | 倍密度ディスク (A disk created to hold data at twice the density (bits per inch) of a previous generation of disks. Early IBM PC floppy disks held 180 KB of data. Double-density disks increased that capacity to 360 KB. Double-density disks use modified frequency modulation encoding for storing data) |
| dynamic disk | ダイナミック ディスク (A physical disk that provides features that basic disks do not, such as support for volumes that span multiple disks. Dynamic disks use a hidden database to track information about dynamic volumes on the disk and other dynamic disks in the computer. You convert basic disks to dynamic by using the Disk Management snap-in or the DiskPart command-line tool. When you convert a basic disk to dynamic, all existing basic volumes become dynamic volumes) |
| Dynamic Disk Fair Share | ダイナミック ディスク フェア シェア (A feature that prevents sessions from over-utilizing disk usage by equal distribution of disk I/O among sessions) |
| Edit Virtual Hard Disk Wizard | 仮想ハード ディスクの編集ウィザード (A wizard that is used by advanced users to perform specific operations on their existing virtual hard disks such as compacting their virtual hard disk, merging it, converting it to another type or expanding its size) |
| floppy disk | フロッピー ディスク (A reusable magnetic storage medium. The floppy disk used today is the rigid 3.5-inch microfloppy that holds 1.44 MB. It is called floppy because the first varieties were housed in bendable jackets) |
| floppy disk drive | フロッピー ディスク ドライブ (A hardware device that reads data from and writes data to floppy disks) |
| hard disk | ハード ディスク (An inflexible platter coated with material in which data can be recorded magnetically with read/write heads) |
| hard disk drive | ハード ディスク ドライブ (A hardware device, or a logical partition of it, that reads data from and writes data to hard disks) |
| high-density disk | 高密度ディスク (A floppy disk that can hold up to 1.44 MB) |
| hybrid disk | ハイブリッド ディスク (A hard disk that contains a small amount of solid-state nonvolatile memory which, when used as a cache, can realize significant benefits such as faster booting, extended battery life, and a more rugged PC) |
| hybrid hard disk | ハイブリッド ハード ディスク (A hard disk that contains a small amount of solid-state nonvolatile memory which, when used as a cache, can realize significant benefits such as faster booting, extended battery life, and a more rugged PC) |
| leaf disk | リーフ ディスク (The last disk in a chain with no child disks attached to it) |
| MBR disk | MBR ディスク (A disk that uses the master boot record (MBR) partition style) |
| Microsoft Disk Operating System | Microsoft ディスク オペレーティング システム (A Microsoft computer operating system with a command-line interface that is used to control many internal computer functions, such as running programs and organizing and maintaining files) |
| New Virtual Hard Disk Wizard | 仮想ハード ディスクの新規作成ウィザード (A wizard that is used by advanced users to create custom virtual hard disks for virtual machines. The purpose of the New Virtual Hard Disk Wizard is to gather the basic information from the user necessary to create a new virtual hard disk) |
| physical disk resource | 物理ディスク リソース (A disk on a cluster storage device. Physical disks are supported as cluster resources by a Resource DLL) |
| Primary disk | プライマリ ディスク (The hard disk drive that contains the system and boot partitions used to start Windows) |
| quorum disk | クォーラム ディスク (The cluster disk on which configuration data is maintained in the quorum log, cluster database checkpoint, and resource checkpoints. The quorum disk is managed by the quorum resource, which is usually a special kind of physical disk resource) |
| RAM disk | RAM ディスク (A simulated disk drive whose data is actually stored in RAM memory. A special program allows the operating system to read from and write to the simulated device as if it were a disk drive. RAM disks are extremely fast, but they require that system memory be given up for their use. Also, RAM disks usually use volatile memory, so the data stored on them disappears when power is turned off. Many portables offer RAM disks that use battery-backed CMOS RAM to avoid this problem) |
| removable disk | リムーバブル ディスク (A disk that can be removed from a disk drive. Floppy disks are removable; hard disks usually are not) |
| setup disk | セットアップ ディスク (A disk that contains an operating system and can be used to boot a computer) |
| startup disk | 起動ディスク (A disk that contains an operating system and can be used to boot a computer) |
| system disk | システム ディスク (A disk that contains an operating system and can be used to boot a computer) |
| unallocated disk space | 未割り当てディスク領域 (Any unpartitioned and unformatted space on a hard disk) |
| undo disk | 復元ディスク (A virtual hard disk that stores the changes made to a virtual machine's guest operating system and data after the Undo Disks feature has been enabled for the virtual machine. Changes accumulate in the undo disk (.vud) file until you commit or discard the changes. Each time you shut down or turn off a virtual machine, you decide whether to keep, commit, or discard the changes) |
| Universal Disk Format | ユニバーサル ディスク フォーマット (A file system defined by the Optical Storage Technology Association (OSTA) that is the successor to the CD-ROM file system (CDFS). UDF is used for removable disk media like DVD, CD, and magneto-optic (MO) disks) |

| Virtual Disk Service | 仮想ディスク サービス (A set of application programming interfaces (APIs) that provides a single interface for managing disks. VDS uses two sets of providers to manage storage devices. The built-in VDS software providers enable the management of disks and volumes at the operating system level. The VDS hardware providers enable the management of disk storage subsystems and are supplied by the hardware vendor) |
| Windows Disk Diagnostic | Windows ディスク診断 (Feature of Windows that proactively detects impending disk failures and can alert the support center to replace the failing hard disk before total failure occurs. For administrators, this feature will guide them through the process of backing up their data so the hard disk can be replaced without data loss) |
| Windows Disk Protection | Windows ディスク保護 (A feature that helps protect the Windows partition that contains the Windows operating system and other programs from being permanently modified from user session to user session) |
| witness disk | 監視ディスク (For a failover cluster, a disk in the cluster storage that is designated to hold a copy of the cluster configuration database. A failover cluster has a witness disk only if this is specified as part of the quorum configuration) |
| zero power optical disk drive | ゼロ パワー光ディスク ドライブ (Pertaining to the ability to reduce the power consumption of optical disk drives in the operating system to zero to save energy when the drives are not in use) |
