5 Utilities for Repairing Bad Sectors in Mac Hard Drives

Apple is held in high regard for a number of things: branding, design, innovation and security. All these apply to their entire line of products. What cannot be denied, however, is that there is no device that runs flawlessly. Even Apple’s high-end computers—the desktop workstation Mac Pro and the laptop MacBook Pro—can still run into problems that plague every hard drive-based computer. This article aims to help in the repair of one specific problem: bad sectors. What are bad sectors? These are parts of the hard drive that cannot be read or written on for new data. The data stored in those sectors either vanished or got corrupted. Bad sectors also contribute to major slowdown of the computer even in simple processes. They can spread if they are still used, eventually destroying the entire hard disk. What are the causes of this problem? Hard drives are fragile pieces of equipment. It cannot take much impact or stand in high temperatures without getting damaged. When the disk inside the drive touches the head due to shock, it can lead to problems. Power outages that occur during data writing can also be a cause. Bad sectors caused by physical damage are called hard bad sectors, and they cannot be repaired. Another cause of bad sector is the parity bits that got corrupted by malware, resulting in the data not matching when...

The Roots of Social Networking – Where It Began

Social networking sites like Facebook and MySpace have dominated the Internet as the most visited websites in the last seven or eight years, beating out information centric sites such as Wikipedia and the search engines Google and Yahoo.  As it turns out, people have attempted to connect with each other through computers since the very early days of personal computing. Early Nineteen Seventies The earliest social networks were in the form of bulletin boards.  These bulletin boards were not like our current Internet bulletin board systems like online product help forums and online topical forum sites.  The first computer bulletin board was set up in Leopold’s Records in Berkley California in 1972.  This electronic bulletin board was set up as a computer terminal that actually sat next to the community bulletin board within the record store.  Users would come in and hang flyers for the sale of their Volkswagen Bus on the corkboard and then type in their for sale advertisement into the “Community Memory” machine, as they called it.  The Community Memory system hosted local advertisements, questions and advice concerning cost saving measures and requests for the best restaurants in the area.  While this computer system was not connected to a larger online network of computers, the central location of this system being located in a central community hub allowed Community Memory to connect several people in the...

2012 Future of Cloud Computing Survey Results

The results of the 2012 Future of Cloud Computing Survey are in, and the outlook is extremely optimistic. The survey projects cloud-computing technology is poised for a new level of growth and increasing consumer confidence across all platforms. The survey, conducted by venture capital firm North Bridge’s analyst Michael J. Skock, garnered 785 survey respondents, including a mix of C-level executive, IT and other respondents. The results do match up with similar research from IDC, Gartner and other industry analyst firms that found high growth trends. Here are some of the more interesting results from North Bridge’s survey: -Confidence in the Cloud for mission-critical business applications is up from 13 percent in North Bridge’s 2011 survey to 50 percent in their 2012 survey. -Around 85 percent of all new software will be delivered via the Cloud/Software as a Service (SaaS). These results are consistent with IDC’s forecast. -Fifty-five percent of CIOs who responded to the survey will increase spending on SaaS in 2012. -The top three areas in which cloud technologies are most popular (or, as the survey says, where “cloud formations” are coming together) are: backup and archiving (43 percent), business continuity (25 percent), collaboration tools (22 percent), and big data processing (19 percent). -Only 3 percent of respondents view the Cloud as ‘too risky,’ a significant drop from the 10 percent of respondents last year who cited this as a concern. -Venture...
