Primary Master Hard Disk Failure IDE Hard Disk Error and Recovery

IDE (Integrated Drive Electronics) is a commonly used hard drive interface. Motherboards are generally provided with two IDE connectors, IDE0 (Primary IDE) and IDE1 (Secondary IDE). To each of the IDE connector, we can attach two devices at the maximum, where one is given the highest priority and referred as Master Drive while the second one is given low priority and is referred as Slave drive. But sometimes, system prompts that it can't recognize the IDE hard drive as it has failed. These are the cases when Hard Disk Recovery becomes necessary to retrieve lost data.

One of the symptoms that it shows, while hard disk failure is the occurrence of error messages as:
"Primary Master Hard Disk Failure"

As the error message suggests, system is referring to failure of primary master hard drive. It is also sometimes denoted as drive 0, which is entirely dependent upon number of drives installed and BIOS type.

Primary Master Hard Disk Failure IDE Hard Disk Error and Recovery

Cause of Error Message:

Hard disk has failed to correctly communicate with the system, most likely due to physical failure. The corresponding causes could be: read/write head crash, actuator arm failure, spindle motor crash, disk controller problems, firmware corruption or electronic issues. In few cases, bad cabling could also be a root cause for this error message. These cables may turn faulty due to issues like heat, wear and tear etc.

Solution

Users are required to consider following solutions:
o If hard disk has gone physically bad, system user should immediately turn it off. The hard drive should be replaced with a new one and data can be restored from a recent backup on the new drive. If backup is unavailable or faulty, Data Recovery service can serve the purpose of optimum recovery.

o If bad cabling is the issue, user can replace the faulty cables with new ones.

Computer Forensics Jobs

Computer forensics is a fast-growing career field, offering immense potential for jobs in law enforcement, military, intelligence agencies, corporations, and businesses. The job opportunities are skyrocketing, commensurate with the rapid spurt in computer crimes.

Computer crimes, in the beginning, had only a sporadic occurrence. Now, it has become a fact of life that has to be dealt with by law enforcement agencies. As computer applications and the Internet have become inseparable parts of life, the instances of wrong-doing with the help of computers are the order of the day.

For tackling crimes, the computers themselves have to be scanned thoroughly to determine whether they have been used for illegal or unauthorized activities or frauds.

Computer Forensics Jobs

This can be done only by computer forensic experts who gain the tools through on-the-job experience, certification programs, and other qualifications.

Computer forensic professionals are known by many titles, such as computer forensic investigators, digital media analysts, and digital forensics detectives. Each one describes the same career as it is concerned with the investigation of digital media.

A computer forensic specialist earns salaries ranging from ,000 to 0,000 per year, depending upon one's skills and experience and the company and organizations he works for. Private companies offer more lucrative salaries than law enforcement agencies.

A graduate degree in computer forensics can help advance the career, making one eligible for positions as forensic team leaders or bureau supervisors. Fifty percent of FBI jobs require computer forensic applications.

Consulting is an attractive field for computer forensic professionals, as they are independent and free agents. They take up assignments at will and charge hefty sums for their time spent on the job. They bill the client per hour. The hourly remuneration ranges from 5 to 0, depending upon the kind of job they complete.

There will be an ever-increasing demand for qualified security and computer forensic professionals. Computer and networking skills no longer suffice as security is of prime importance for the server, work station, or router.

Computer History and Impact of Computers to the World

Personal computers have completely revolutionized the way the world, lives, works and conducts business. Strictly-speaking, computers arrived on the scene way back in 1936 when one Konrad Zuse produced what was then called the Z1 computer. This was a cumbersome machine that could perform simple calculations and also crunch simple data. This was not as sophisticated as what we have today but it served to set the foundation for further research and in 1944, John Atanasoff and Clifford Berry from Iowa University built on this model and produced several innovations of the computer which was capable of producing arithmetic calculations, parallel [processing, memory regeneration and other simple computing tasks. The research was taken further at Harvard University, then IBM, the business conglomerate joined the fray and in 1953 produced what was then the world's first sophisticated computer. Even then, it was still large, occupying entire floors and consuming untold power.

As we have mentioned, computers have completely changed the way we live and work. Today, computers are in almost every office. There are still offices in some parts of the world which still don't have computers but this is now rare because without computers, work is inefficient and cumbersome. Take for instance calculations. It would take days for companies to do simple calculations not to mention companies that deal with lots of material and inventory. Computers make this work simple and allow businesses to become more efficient on a day to day basis.

Another use of computers is communication. With computers has come the wondrous world of the Internet or what is called in other circles, the World Wide Web or Information Superhighway. As much as computer has changed the way we work, they have also revolutionized the way we communicate. The term "the world is a smaller place" or phrases like "global market place". This is because the Internet has made communication so easy and seamless that there has people can communicate instantaneously regardless of what part of the globe they are located. The world of email, although it hasn't completely resulted in the eradication of snail mail, has nevertheless caused a decline in visits to the post office or the purchase of stamps. All this is because people now sit behind a computer and email back and forth. To go even further, specialized Internet software run by many major companies such as Microsoft, Yahoo and Google has made it possible to chat in real time with someone on the other side of the globe. Video conferencing has also been made possible. This has completely changed the way we conduct meetings. Businesses can now even open branches in other countries faster because the top level management can communicate with lower management via video conferencing. People can actually see each other regardless of where they are located and all this is courtesy of the advent of computers and the Internet. Computers have evolved a lot since and are now in almost half of all US households and most offices in the rest of the world.

Cybercrime and How to Prevent It

The growth of e-commerce has given rise to a new concern for security, cyber crime. Concerns regarding the same are constantly rising all over the world. Viruses are no more the only threat to one's computer; even a simple download from an illegitimate site can destroy your system and perhaps steal away all your hard earned money. The new kid on the block, internet banking fraud, is making its name on the scene. It is one of the most dreaded forms of cyber crime, leaving people clutching for their money.

The first level of the security problem starts from the developing stage i.e. when the web site is being designed. If the developers leave any sort of a loop-hole, an eventual hacker can extract confidential information from the website. To fix this problem the website planners must ensure their script is very well planned and tested, especially those which deal with private info. In such cases, using a Digital Certificate (Digital ID) in conjunction with SSL encryption provides complete security for all parties involved in a transaction.

The second layer of the problem lies with the users, who generally end up giving their vital information to various sites which are not verified. In fact, major crimes happen due this very reason! Also, we should spare a thought to the most common cyber foe: viruses. Viruses are known to make their ways into a computer most inconspicuously, often disguised. One needs to take a lot of care to avoid these deadly pc-killers. The users should avoid p2p networks (peer-to-peer). One should try and download only from a known & trusted source, or else, you may end up granting free passage to malware.

Cybercrime and How to Prevent It

For cracking down on viruses there are many good anti virus applications, including NOD 32, AVG, and Norton Antivirus. Although they tend to take a toll on the processing speed, they are necessary. Firewalls are also used to further enhance the security of the computers, by posing as a security "check gate" for your computer. Every year, there is an increased number of reports of cyber crime related cases. From a small credit fraud, to a major bank heist, it's all been done. Let's just hope it doesn't go any further.
