Superformatting
Superformatting is the process of formatting a floppy disk at a capacity that the disk is not designed for. It can ruin a floppy disk, but it is used in some floppy-based Linux distros to increase the room for applications and utilities. muLinux is a notable example of this technique. Another common use (which is not as popular nowadays) was to format low-density 3.5-inch or 5.25-inch floppies as high-density, or in the case of 3.5-inch disks, even extra-high density (HD-36). "Notched" disks will usually turn up a lot of bad sectors, especially if the formatted capacity is a considerable (1.5 to 3) number of times higher than intended. Superformatting is usually done with a low-level format (such as "FORMAT /U" in DOS and "fdformat Fdformat is the name of two unrelated programs: * A command-line tool for Linux that " low-level formats" a floppy disk. * A DOS tool written in Pascal by Christoph H.

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Computer Application
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MuLinux
muLinux is an Italy, Italian, English language, English-language lightweight Linux distribution maintained by mathematics and physics professor Michele Andreoli, meant to allow very old and obsolete computers (80386, 80486 and Pentium Pro hardware dating from 1986 through 1998) to be used as basic intranet/Internet servers or text-based workstations with a UNIX-Unix-like, like operating system. It was also designed for quickly turning any 80386 or later computer into a temporary, powerful Linux machine, along with system repair, education, forensic analysis and what the developer called ''proselytizing''. In 2004 reviewer Paul Zimmer wrote, "Although there are several other single-floppy Linux distributions, none can match muLinux's extensive and unique combination of useful features."Zimmer, Paul, muLinux: A Brief Introduction', The Linux Information Project, 2004, retrieved 16 August 2008 The last version update was in 2004, when further development of this "linux-on-a-floppy" dis ...

Floppy Disk Format
Floppy disk format and density refer to the logical and physical layout of data stored on a floppy disk. Since their introduction, there have been many popular and rare floppy disk types, densities, and formats used in computing, leading to much confusion over their differences. In the early 2000s, most floppy disk types and formats became obsolete, leaving the -inch disk, using an IBM PC compatible format of 1440 KB, as the only remaining popular format. Different floppy disk types had different recording characteristics, with varying magnetic coercivity (measured in oersteds, or in modern SI units in amperes per meter), ferrite grain size, and tracks per inch (TPI). TPI was not a part of the physical manufacturing process; it was a certification of how closely tracks of data could be spaced on the medium safely. The term density has a double meaning for floppy disks. Originally, single density and double density indicated a difference in logical encoding on the same t ...

Fdformat
Fdformat is the name of two unrelated programs: * A command-line tool for Linux that " low-level formats" a floppy disk. * A DOS tool written in Pascal by Christoph H. Hochstätter that allows users to format floppy disks to a higher than usual density, enabling the user to store up to 300 kilobytes more data on a normal high density 3.5" floppy disk. It also increases the speed of diskette I/O on these specially formatted disks using a technique called "Sector Sliding". In this technique, the physical sectors on the disk are ordered in such a way that when the drive advances to the next track, the next logical sector waiting to be read is immediately available to the read head. See also * 2M, a similar program that offers even higher capacity * DMF, a high-density diskette format used by Microsoft * VGA-Copy VGA-Copy is an MS-DOS program to copy floppy disks. It is able to read defective floppy disks. Development VGA-Copy was created by the German software develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
