Multiple issues wikify March 2012 orphan February 2009 unreferenced August 2007 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 inch or 5 inch floppies as high density, or in the case of 3.5 disks, even extended density HD 36. Notched disks will usually turn up a lot of bad sectors, especially if the formatted capacity is considerably 1.5 to 3 times higher than intended. Superformatting is usually done with a low level format such as format u in DOS and fdformat in Linux. Category Floppy disk drives ... more details

F6 disk is a colloquial name for a floppy disk containing a Microsoft Windows NT device driver for a SCSI or RAID system. F6 disks are used by all NT based versions of Windows, including Windows 2000 , Windows Server 2003 , and Windows XP . Starting with Windows Vista , floppy F6 disks are obsolete its setup process supports loading third party drivers from USB flash drive USB drives and CD ROM CD ROMs . Usage An F6 disk is named after the manner in which it is used. During the installation process for Windows, the Setup program must load device drivers for the disk system on which Windows will be installed. Unless the disk system has been established on the market before the finalization of the particular Windows release being installed, the drivers are not included on the Windows installation discs, and they must be loaded by means of an F6 disk. An F6 disk is loaded in Windows setup by pressing the Function key F6 key immediately when Windows Setup starts. The message Press F6 if you need to install a third party SCSI or RAID driver... is briefly flashed on the screen every time Windows Setup starts. An F6 disk contains device drivers in its root directory . Prior to Windows Vista, F6 disks were always floppy disks because, at the point the F6 prompt is shown, Windows Setup has not loaded the drivers for any media type other than floppy disks. Support for USB drives and CD ROMs was added in Windows Vista. Device drivers for RAID and other disk controllers are often provided on CD ROMs by the manufacturers, but they must be copied to an F6 disk if they are to be used during Windows Setup. An alternative approach is to slipstream computing slipstream the required SATA SCSI SAS RAID EIDE drivers into the Windows installation files directory e.g. i386 for the x86 variety by means of software like nLite and then create an ISO image that can be burned to CD or DVD media.

otheruses http www.auspex inc.com Auspex, Inc. was founded 1985 by Michael Henney , Burt Brockman and Terry Kisner to develop SCADA software systems. In 1986, Rich Newell joined Auspex and the company started providing software support for SGM, Inc. s RCS 7 line of SCADA products. In 1987 Auspex acquired the RCS 7 product line from SGM, Inc.. In 2005, Auspex started marketing LeakTrack 2000, a liquid pipeline leak detections system. Auspex Systems was founded in 1987 by Larry Boucher , CEO of Adaptec , introduced the first network attached storage NAS devices. One of the unique features of their systems was the ease with which volumes could be transparently mirrored and migrated between physical disks. They became a leading provider of enterprise storage in the mid 1990s but fell behind NetApp in the field. Early cabinet rack models held sets of 3 4gb disks the size of small shoeboxes. Their 4Front or NS2000 model, initially offered in 1999 as a stackable system, held drawers of disks and was plagued by Mylex RAID controller issues which contributed to their bankruptcy in June 2003. Their last product, the NSc3000, was the first multi vendor SAN NAS gateway and essentially kept the same NAS front end but could connect via fibre channel to any SAN disk array. When the company was liquidated in 2003, its patent portfolio was acquired by NetApp and its services business went to GlassHouse Technologies .

Orphan date February 2009 Crazy Boot is a computer virus that infects the Microsoft Windows operating systems causing no physical damage nor direct loss of information it would be known as a hoax to some. If the host computer is Booting booted from an infected floppy disk , this virus makes it look as though all physical hard drives have been lost. Crazy Boot spreads through unprotected disks easily. It spreads only on diskettes, not by file distribution. The virus resides in memory, it infects the master boot record s of all physical hard disks and infects the boot sector s of floppy disks. If Crazy Boot is in memory, any access to the boot record is rerouted to a copy of the original boot sector. When the virus infects a hard drive , it makes a copy of the partition table an important part of the system area , writes the copy, and deletes the original partition table. To read the partition information, Crazy Boot must be active in memory. If users boot from a floppy disk not infected by this virus in order to avoid it, all physical hard drives are inaccessible by normal means.

First introduced in the early 1990s, random orbit sanders combine the speed and aggressiveness of a belt sander with the ability to produce a finer finish than that available from a standard, slow speed orbital finishing sander . The random orbit sanding pattern is produced by simultaneously spinning the sanding disk and moving it in an ellipse. This ensures that no single part of the abrasive material travels the same path twice. Because of this unique random sanding action, the tool does not leave swirl marks , and is not sensitive to the direction of the wood grain . This makes it useful when sanding two pieces of wood that meet at right angle s. Random orbital sanders use sandpaper disks, and many include integrated Dust collection system dust collectors . Disks are attached using either pressure sensitive adhesives or a hook and loop system. On models equipped with a dust collection feature, a vacuum effect sucks sanding dust through holes in the paper and pad, feeding it to a bag or canister.

The holes are placed on each disk at equal angled radial lines and a given distance from the centre but they do not align with each other. A sample of phosphorescent material is placed in between the two disks. Light coming in through a hole in one of the discs excites the phosphorescent material which then emits light for a short amount of time. The disks are then rotated and by changing their speed the length of time the material glows can be determined.

dablink Discworld , spelled with a c , is a series of novels by Terry Pratchett and its fictional setting. Image Diskworld1.jpg thumb Cover to Diskworld issue 1 1988 Diskworld ISSN 0899 4838 was a disk magazine for the Apple Macintosh computer system, published by Softdisk beginning in 1988. It was a sister publication of Softdisk disk magazine Softdisk for the Apple II , Loadstar for the Commodore 64 , and Big Blue Disk for the IBM PC . Diskworld was originally designed and created by Sean Golden Managing Editor , Jeff Billings Senior Programmer and Lynda Fowler Junior Programmer . Sean Golden wrote the original Diskworld shell program which provided access to the monthly disk contents. He also wrote most of the editorial content each month. Jeff Billings and Lynda Fowler developed monthly productivity, utility or game programs which were published on the disk. Jeff and Lynda also provided some editorial content, and Sean also contributed programs. Free lance programmers also provided content for a fee. The product was broken down into editorials, articles, reviews, artwork and software, all presented with the custom shell program which allowed users to run the disk without having to swap out system disks on the original Macintosh. The early issues were published on 400K disks, but moved to 800K disks when the 400K disks become obsolete. Eventually the shell program was able to remove the Mac OS when hard drives became commonplace. That allowed for more content to be published on each disk. Jeff Billings left the company and Lynda Fowler became Senior Programmer. When Sean Golden was promoted to Softdisk Publishing, Inc. Publisher, Lynda Fowler became Managing Editor of Diskworld. Later, Diskworld was renamed Softdisk for Mac , but it ceased publication by the end of the 1990s along with the other disk magazines published by Softdisk other than Loadstar , which broke off as an independent company and continued into the 2000s as the company moved more into Internet ... more details

Unreferenced auto yes date December 2009 The IBM e X tended D ensity F ormat XDF is a way of formatting standard high density 3.5 and 5.25 floppy disk s to larger than standard capacities. It is supported natively by IBM s PC DOS versions 7 and 2000 and by OS 2 Warp 3 onward, using the XDF and XDFCOPY commands directly in OS 2 . When formatted as XDF disks, 3.5 floppies can hold 1860 abbr title 1024 bytes KB abbr , and 5.25 floppies can hold 1540 KB, using different number of sectors as well as different sector size per track not all sectors in the same track are of the same size . However, the first cylinder uses standard formatting, providing a small FAT12 section that can be accessed without XDF support and on which can be put a README ReadMe file or the XDF drivers. Floppy distributions of OS 2 3.0, PC DOS 7 and onward used XDF formatting for most of the media set. Floppy disks formatted using XDF can only be read in floppy disk drives that are attached directly to the system by way of a Floppy disk controller FDC . Thus, USB attached floppy drives cannot read XDF formatted media.

Unreferenced stub auto yes date December 2009 Stable storage is a classification of computer Computer data storage data storage technology that guarantees atomicity database systems atomicity for any given write operation and allows software to be written that is robustness computer science robust against some hardware and power failures. To be considered atomic, upon reading back a just written to portion of the disk, the storage subsystem must return either the write data or the data that was on that portion of the disk before the write operation. Most computer hard disk drive disk drives are not considered stable storage because they do not guarantee atomic write an error could be returned upon subsequent read of the disk where it was just written to in lieu of either the new or prior data. Implementation Multiple techniques have been developed to achieve the atomic property from weakly atomic devices such as disks. Writing data to a disk in two places in a specific way is one technique and can be done by application software . Most often though, stable storage functionality is achieved by Disk mirroring mirroring data on separate disks via RAID technology level 1 or greater . The RAID controller implements the disk writing computer algorithm algorithms that enable separate disks to act as stable storage. The RAID technique is robust against some single Hard disk failure disk failure in an array of disks whereas the software technique of writing to separate areas of the same disk only protects against some kinds of internal disk media failures such as bad Disk sector sectors in single disk arrangements.

Inappropriate tone date February 2008 The SparQ drive was a removable drive made by SyQuest Technology The drive was available as an internal version with Integrated Drive Electronics IDE interface, and an external version for the parallel port . The Cartridge electronics cartridge could store 1 Gigabyte GB of data and, as removable disk hard drive , contained a solid hard disk platter on which the data are stored. When the SparQ drive was launched, it was primarily noticed for its relatively low price. Compared to the Zip drive , a 100 MB disk could cost 22 USD while a 1 GB SparQ disk could cost 39 USD. Just a few months after the launch, people began to complain that the drives had serious quality issues, causing them to break down. The damage to its public image and warranty obligations of Syquest were major factors behind the company s bankruptcy. After the bankruptcy, SyQuest kept its rights to make and sell the drive, which it continued to sell directly to consumers via its web site. The price increased compared to when the drive was launched, so it is primarily for businesses that still rely on the drive and people who want to read old SparQ disks. As of October 2008, the web site was no longer active. The SparQ was noteworthy for a serious failure mode which damaged SparQ disks in a way that caused them to damage subsequent SparQ drives in which they were placed. Simply, putting a broken disk in a SparQ drive will cause the drive to break any new disks placed in that drive. These broken disks could break additional drives, breaking most of the drives in an office in short order.
