Ontrack Disk Manager
Disk Manager is a discontinued software (that was a popular 1980s and 1990s) and documentation package for MS-DOS and PC DOS computers, useful for self-installing personal computer Hard disk drive, hard disks. It was written by Ontrack, a company that is now part of KLDiscovery. Installation covered different aspects: * explaining personal computer hardware concepts * documenting switches of many of the existing disks * putting into place custom device drivers which circumvented Enhanced BIOS, BIOS limitations, notably those related to maximum disk or partition size and logical block addressing * providing testing and informational utilities Drivers could be either DOS-type, or replacement master boot record code. Diskettes with Disk Manager were provided by some disk manufacturers (e.g. IBM), in custom OEM versions, supporting all of their models. Not long after launching in 1985, Ontrack also started providing computer disk data recovery services as ''Ontrack Data Recovery''. ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Computer Hardware
Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random-access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. By contrast, software is a set of written instructions that can be stored and run by hardware. Hardware derived its name from the fact it is '' hard'' or rigid with respect to changes, whereas software is ''soft'' because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. History Early computing devices were more complicated than the ancient abacus date to the seventeenth century. French mathematician Blaise Pascal designed a gear-based device that could add and subtract, selling around 50 models. The steppe ...

Device Driver
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface. Purpose The main purpose of device drivers is to provide abstraction b ...

Enhanced BIOS
Logical block addressing (LBA) is a common scheme used for specifying the location of blocks of data stored on computer storage devices, generally secondary storage systems such as hard disk drives. LBA is a particularly simple linear addressing scheme; blocks are located by an integer index, with the first block being LBA 0, the second LBA 1, and so on. The IDE standard included 22-bit LBA as an option, which was further extended to 28-bit with the release of ATA-1 (1994) and to 48-bit with the release of ATA-6 (2003), whereas the size of entries in on-disk and in-memory data structures holding the address is typically 32 or 64 bits. Most hard disk drives released after 1996 implement logical block addressing. Overview In logical block addressing, only one number is used to address data, and each linear base address describes a single block. The LBA scheme replaces earlier schemes which exposed the physical details of the storage device to the software of the operating sys ...

Master Boot Record
A master boot record (MBR) is a type of boot sector in the first block of disk partitioning, partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0. The MBR holds the information on how the disc's sectors (A.K.A. "blocks") are divided into partitions, each partition notionally containing a file system. The MBR also contains executable code to function as a loader for the installed operating system—usually by passing control over to the loader's second stage, or in conjunction with each partition's volume boot record (VBR). This MBR code is usually referred to as a boot loader. The organization of the partition table in the MBR limits the maximum addressable storage space of a partitioned disk to 2 Tebibyte, TiB . Approaches to slightly raise this limit utilizing 32-bit arithmetic or 4096-byte sectors are not officially s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpeedStor
Storage Dimensions, Inc., was an American computer company active from 1985 to 1998 and based in Milpitas, California. The company sold data storage hardware—chiefly magnetic-tape- and hard-drive-based storage subsystems (with the hardware manufactured by other companies)—and developed server software for businesses. The company was perhaps best known for their SpeedStor disk utility software for MS-DOS and Windows. From 1987 to 1992, the company was a subsidiary of Maxtor. History Storage Dimensions was founded by David A. Eeg and Gene E. Bowles in Los Gatos, California, in 1985. Both Eeg and Bowles had worked for Atasi Corporation, a San Jose–based maker of 5.25-inch hard disk drives that was acquired by Tandon in 1987. After leaving Atasi, the two founded Storage Dimensions with their own savings. The company's first product was the AT160F, a hard disk drive subsystem for the IBM Personal Computer AT and compatibles that comprised one or two 160-MB HDDs manufactured b ...
