Abstract This paper examines how Redundant Array of Independent Disks (RAID) describes array configuration and applications for multiple, inexpensive hard disks, providing fault tolerance (redundancy) and improved access rates (RAID concept). RAID provides a way to access multiple individual disks as if the array were one larger disk, spreading data access out over these multiple disks, reducing the risk of losing all data if one drive fails, and improving access time. It looks at how RAID is commonly used in large file servers, transaction of application servers, where data accessibility is critical and fault tolerance is required, and explores ten types of RAID, presenting a myriad of feature trade-offs that must be appropriately mapped to critical implementation requirements.
From the Paper "RAID 1 allows two or more disks to mirror each other (Achieving fault tolerance by using RAID). This configuration produces slow writes, but relatively quick reads, and facilitates high data availability on servers because a single disk can be lost without any loss of data. When more than two disks make up the mirror, the RAID 1 array can lose multiple disks as long as a complete mirrored pair is not lost. On the downside, the amount of physical disk space required is twice the space required to store the data. Therefore, Level 1 is most often used for applications that require very high data availability."
Abstract Herniated disks can be treated in a variety of ways since doctors seem to like some methods better than others. The conventional method of treatment is hot/cold treatment with stretch exercises. The best method of treatment is prevention.
Abstract This paper discusses the magnetic hard disk drive and how it works, from its creation to the present day. It also discusses possible future technological advances. It then discusses the varied uses of hard drives and the impact the device has had on society over the past few decades.
From the Paper "Personal computer technology has grown exponentially over the past few decades, but at its core, construction remains focused on certain necessary components. The magnetic hard disk drive is one of those components. Despite its importance and widespread use, many casual computer users know little about the history of or workings of this device. The magnetic hard disk drive, or simply hard drive, as it is known by most computer users, has come a long way and evolved over fifty years to become the ubiquitous storage device the world knows today."

From the Paper "The Hard Disk Drive is a mechanical device that uses electromagnetism to store data in a form of binary magnetic codes. It is in the HDD that all of the computer programs and data are accessed by the user. HDD is known as a permanent storage device as distinguished from the semiconductor's temporary memory devices. There are other types of permanent storage used in computers, the others being the floppy disks, compact disks, digital memory tapes and lately, the solid state devices (SSD) which are commonly called as USB memory devices or Flash Drives. The hard disk differs from the others primarily in three ways: physical size (usually larger dimensions), speed (usually faster data seek time), capacity (more amount of memory that can be stored), permanence (usually is permanent and is not removable), and storage mechanism. Storage mechanism refers to how the data is stored and retrieved for future use."
Abstract This paper discusses RAID, the Redundant Array of Independent or Inexpensive Disks. The paper describes this as a type of computer disk drive or storage media that uses two or more drives in association for fault tolerance and performance. The paper contends that RAID is important because the sudden eventuality of data losses can be overcome by an organization so that information and data can be securely recovered. The paper explains that RAID is used to provide real-time, around-the-clock backup of the hard disk.
From the Paper "RAID stands for Redundant Array of Independent or Inexpensive Disks, a type of Computer Disk drives or storage media that uses two or more drives in association for fault tolerance and performance. The use of RAID disk drives are normally made on servers in a computer network environment. (RAID: www.webopedia.com) Fault tolerance is the capability to react smoothly and thereafter recover from a sudden hardware or software breakdown. Several stages of fault tolerance exist, the lowest stage being the capability to continue running the system in the event of power disruption. A lot of fault-tolerant computer systems emulate every function which indicates every function is executed on two or more identical systems, such that in the event of breakdown of a particular system the other one can continue operation from that stage onwards."
Abstract This study explores impacts of mergers and acquisitions (M&A) processes on non-executive employees within merging and/or recently-merged companies. The particular subject of this study was the Hitachi Global Storage Technologies (HGST) hard disk drive (HDD) manufacturing company and the impact on its lower-ranked (i.e. non-executive and non-managerial) employees of the two-year-old (at the time of this study) merger process of HDD manufacturing entities at IBM and Hitachi Ltd., that ultimately formed the present company. Hitachi Global Storage Technologies (HGST) as it now exists, was formed in two separate mergers and acquisitions (M&A) stages: (1) the June 2002 merger of the existing Hard Disk Drive (HDD) units of IBM and Hitachi Ltd. (2) By the January 2003 total absorption by Hitachi Ltd. of IBM's remaining HDD facilities.

Conclusions
From the Paper "Currently HGST, based in San Jose, California, in the far-western region of the United States, has nine manufacturing bases worldwide, and over 24,000 employees, most of whom were transferred from either IBM (about 18,000 transferred employees) or Hitachi Ltd. (about 6,000 transferred employees). Merger processes began early in 2002, when Hitachi Ltd. first purchased a 2 billion dollar share of IBM's HDD unit. Those merger processes were completed on January 6, 2003, when Hitachi then purchased the remaining portion of IBM's HDD business from IBM. HGST is now a separate hard disk drive manufacturer, owned in full by Hitachi Ltd. The study was undertaken with the goal of better understanding how such mergers and acquisitions (M&A) processes (both these in particular, and by association, other such processes) typically impact attitudes, morale, and job commitment of rank and file employees, during the various stages (i.e., beginning, middle, and end) of such merging and acquiring processes."
Abstract The paper relates that in the summer of 1992, computer gadgets company Hewlett-Packard launched onto the market the smallest hard disk ever made, the Kittyhawk. The paper describes the success of this design but reveals the disk's short-term success and the closing of the Kittyhawk project. The paper explains the failures regarding the target market and the costs involved. The paper concludes that the short success told Hewlett-Packard that they could do it, but the failure showed them they must increase their efforts in order to succeed.
From the Paper "In the summer of 1992, computer gadgets company Hewlett-Packard launched onto the market the smallest hard disk ever made, the Kittyhawk. It was 1.3 inches in diameter and had a storage capacity of 20 megabytes, representing the latest innovation of those times. That year, HP's Disk Memory Division, responsible for the creation of the Kittyhawk registered a total of $519 million sales revenues, when the industry leaders, IBM and Seagate Technology registered $4 billion and $5 billion from selling their hard drives."

A review of the article 'The Iron Cage Revisited: Institutional Isomorphism and Collective Rationality in Organizational Fields' by Paul J. DiMaggio and Walter W. Powell.
Abstract This paper explores industries that best illustrate the concepts in DiMaggio and Powell's article, 'The Iron Cage Revisited: Institutional Isomorphism and Collective Rationality in Organizational Fields'. According to the paper, isomorphism's illustration in the disk drive industry is analyzed from the coercive, mimetic and normative mechanisms that the authors analyze and present in their article.

Isomorphism & Storage Technologies: Made for Each Other
Exploring the Facets of Institutional Isomorphism as it Relates to the Storage Industry
From the Paper "In terms of coercive isomorphism, the disk drives' industry has at times be hypocritical in their practices on the one hand and their reliance on government intervention on the one hand. When Japanese manufacturers were the first to generate the highest densities and the lowest cost per GB and in turn beat other nations; manufacturers to the next level of performance, US and westernized nations aggressively used anti-dumping policies through their governments in an attempt to slow down the technological leads in other nations. Yet these same disk drive manufacturers would load up their channels and report shipped storage products as sold on their balance sheets when they had merely been sent to distribution partners. This level of coercive isomorphism became heightened and was driven by manufacturers looking for differentiation through public policy, having exhausted product-related differentiation as products at this point were different only on price and their date of availability."
Abstract The paper relates that Hewlett-Packard's Kittyhawk project for the emerging handheld computing market never succeeded in the commercial market due to unforeseen events and mistakes. The paper explains the main reason for the failure, which involved the handheld computing market, project expectations, the design limitation and the project's resource allocation. The paper then discusses the actions that the Disk Memory Division (DMD)and the Kittyhawk team could have taken to prevent the failure of the project and the department.

Avoiding Failure
Conclusion
From the Paper "The Kittyhawk project was initiated to help HP become a major player in the hard disk industry in the long run. Although HP has been selling disk drives since 1984 it was still a niche player in the industry by 1991. Bruce Spenner, the general manager of HP's Disk Memory Division (DMD), believed that HP needed to develop a new hard disk that would "take the computing market by storm" (Rogers 1997, p 51) if it was to achieve its goal of becoming a big player in the hard disk industry. Therefore the Kittyhawk project set out to develop a new small and robust hard disk for the emerging handheld computing market. Although the hard disk was completed, it never succeeded in the commercial market due to unforeseen events and mistakes."
Abstract This paper explains the hypotheses of this project, which are: (1) Little can be done to impact a solution's floppy disk speed, (2) SCSI disks no longer affect performance, and (3) much can be done to affect a system's 10th-percentile instruction rate. The author reports, running "Sackbut" on commodity operating systems, such as LeOS and Minix, the experiments proved that exo-kernelizing the saturated online algorithms was more effective than monitoring them. This paper concludes that the author's system sets a precedent for the visualization of robots, and it is expected that cryptographers will improve on Sackbut for years to come. Tables.

Conclusion
From the Paper "Contrarily, this solution is fraught with difficulty, largely due to digital-to-analog converters. Predictably, Sackbut constructs fiber-optic cables. Existing constant-time and classical heuristics use extensible technology to develop the intuitive unification of the partition table and the Turing machine. We view steganography as following a cycle of four phases: synthesis, construction, storage, and emulation. Such a hypothesis is entirely an unfortunate mission but has ample historical precedence. The basic tenet of this solution is the important unification of linked lists and A* search. Combined with the Ethernet, such a claim constructs an analysis of the transistor."
Abstract This paper discusses various facets of computers and information processing, including the choice of best input or output methods for various situations, the best storage devices to use for different information storage needs, and the role of RAM, clock speed, and data storage medium in computer speed.
From the Paper "Different methods of data input are appropriate for different situations. For example the best way to input printed questionnaires is by keying in the data because scanning it in is likely to result in errors ..."

Abstract This paper describes the business activities of Seagate Technology - one of the world's largest manufacturers of computer disk drives and related data storage devices. When its stock price was undervalued, the management of Seagate worked with a private equity firm to plan a restructure of the company. The author gives a detailed account, together with tables and charts, of the leveraged buyout of Seagate's disk drive operations, finishing with an account of the company's position in the market today.

Aftermath
From the Paper "By undertaking this transaction, Seagate is hoping to allow its shareholders to realize full value for the company, by distributing the VERITAS stock tax-free and by selling the disk drive operation at a fair market value. It is necessary to divest the VERITAS shares in a separate transaction since this is done through a tax-free stock swap. If the company simply sells its VERITAS stock and buys back some shares of its own stock, it will have to pay for the tax; besides, the ability of Seagate to sell off its VERITAS stake was limited by its prior agreement with VERITAS. Previously, Seagate tried repurchasing its own stock in the market to raise its stock price; however, this had little impact on the stock price.
"As a result of this leveraged buyout, Seagate and its shareholders are the obvious winners as they were saved from tax liabilities. VERITAS and Silver Lake Partners are also benefactors of this transaction. Silver Lake stands to make a huge profit from this restructuring and VERITAS stakeholders received an attractive gain from the buyout. The ultimate loser from this transaction is the government because of the millions lost in tax revenue."
Abstract This paper is about Preston Tucker: his life details, his products and his company. It also describes his dreams, as depicted in the movie "Tucker" and how he embraces the entrepreneurial aspects of American business.
From the paper:
"Preston Tucker was a car salesman and inventor. Anticipating WW II, he created a high-speed armored car with a gun on a turret. The army thought that the car was too fast but loved the turret, confiscated the patents and used them during the war. Tucker was given contracts to build turrets for bombers and made his fortune. Tucker dreamed of building a passenger car with innovations such as seat belts, disk brakes, rear engine, safety glass, pop-out windshields, a fully automatic transmission, and self-correcting headlights. The car that he designed and produced was ahead of its time in terms of safety and performance."

Abstract This paper discusses the history and the development of the computer from the first primary abacus to the super fast Internet. It looks at how people's lives have changed and the effect on the quality of life and the workplace.
From the Paper "People everywhere in the world are using computers right now. They use them in cars, on planes, and even to add, subtract, multiply, and divide billions of problems in seconds. You may have used a computer today and never even knew it.
"The word computer comes from its root word compute, which means to solve problems. The first computer was made over 2000 years ago. It is called the abacus. This wooden rack has horizontal wires with a set of beads attached to it. Each set represents either the ones, tens, hundreds, or thousands place. The beads are moved along the wires according to the numbers being counted or added, making it easy to solve regular arithmetic problem."
