Hard Drive Failure - What Goes Wrong & Can You Rely on Data Recovery?

The hard disk drive in your computer is the place where the data is stored, and the data is at its most current. So, if it fails and there is not a current backup then it can be a very serious problem.

Why will a disk fail?

Data Collection Tools

Data on a hard drive is stored on a circular platter that spins at anything from 5400 rpm to 15,000 rpm., with a read/write head mounted on an arm that positions it across the platter to access data. This head "floats" very close to the surface by dint of an aerodynamic effect, add to this movement and proximity the potential for heat generation and there is suddenly a lot that can go wrong.

Head Crash

This is when the head touches the surface of the platter whilst it is spinning, this could be the result of an impact or a mechanical failure within the HDA (HDA is the Head Disk Assembly which comprises the head/platter combination).

It is not too difficult to imaging the consequence of such contact, in the worst cases it can strip away the entire recorded surface of the platter leaving just the base material, usually glass.

Media Failure

Hard disk drives "hide" any instance of media failure to maintain a perfectly readable disk, and prevent operating system problems as the result of unreadable sectors. What they do is maintain a set of spare sectors, and when failures occur they reallocate data to one of these spares.

There can come a point where the spares are all used up and the errors begin. Normally the disk is in quite a sever state of failure by now and if the disk is kept working the problems will rapidly multiply.

Electronic Failure

Hard drives are controlled by circuitry that is susceptible to damage from electrostatic discharge or electrical surge. If a component is on the brink of failing then quite a minor electrical "blip" will push it over the edge.

The complexity with a hard drive is that there is code and information stored within memory devices on the drive controller and this is created when the drive is first formatted, so just replacing the electronics will not help.

Alignment failure and head failure.

If any of the read heads within the drive fail, and can no longer turn the magnetic signal going past into something that can be decoded by the drive electronics then again the disk drive has failed. Even if the heads have not failed but mechanical wear means that positioning to the correct place to find data is just not happening, then you can have lots of perfectly well recorded data but not means of accessing it.

Bearing seizure

Platter rotation has to be nice and smooth, any undue vibration can cause positional problems. Following an impact, or just after prolonged use, the bearings that allow the platter to rotate can crumble and seize. The drive cannot spin the platter and no data can be read.

Data Failures

Sometimes the problem lies not with the disk but with the person or system that is using it. The disappearance of a partition or files might actually be user error or the result of an application error, the disk might still be working perfectly well.

Hard Drive Data Recovery

This is the general term for a collection of techniques for getting the data of a failed device and finding a way of returning it in a usable form. This can range from quite a straightforward process, to a highly complex on, and in the worst case an impossible task.

It is tempting to depend on the general reliability combined with a belief that in the unlikely event of a failure a data recovery professional can help. Many firms cite 95% + success rates so why worry? First, the only statistic that matters is whether your disk can be recovered from, 500 other disks might have been recovered from 100%, but if yours has crashed beyond redemption then your data has gone.

Second, even a low cost data recovery will cost more than a 500GB USB disk, so why risk everything to save virtually nothing?

Hard Drive Data Recovery is an option, sometimes a business or marriage saver, but by taking a bit of care it can be an option that you do not need.

Computer Forensics Tools

In general, a computer forensic investigator will use a tool in order to gather data from a system (e.g. a computer or computer network) without altering the data on that system. This aspect of an investigation, the care taken to avoid altering the original data, is a fundamental principle of computer forensic examination and some of the tools available include functionality specifically designed to uphold this principle. In reality it is not always easy to gather data without altering the system in some way (even the act of shutting a computer down in order to transport it will most likely cause changes to the data on that system) but an experienced investigator will always strive to protect the integrity of the original data whenever possible. In order to do this, many computer forensic examinations involve the making of an exact copy of all the data on a disk. This copy is called an image and the process of making an image is often referred to as imaging. It is this image which is usually the subject of subsequent examination.

Another key concept is that deleted data, or parts thereof, may be recoverable. Generally speaking, when data is deleted it is not physically wiped from the system but rather only a reference to the location of the data (on a hard disk or other medium) is removed. Thus the data may still be present but the operating system of the computer no longer "knows" about it. By imaging and examining all of the data on a disk, rather than just the parts known to the operating system, it may be possible to recover data which has been accidentally or purposefully deleted.

Data Collection Tools

Although most real world tools are designed to carry out a specific task (the hammer to hammer nails, the screwdriver to turn a screw, etc.) some tools are designed to be multi-functional. Similarly some computer forensic tools are designed with only one purpose in mind whereas others may offer a whole range of functionality. The unique nature of every investigation will determine which tool from the investigator's toolkit is the most appropriate for the task in hand.

As well as differing in functionality and complexity, computer forensic tools also differ in cost. Some of the market-leading commercial products cost thousands of dollars while other tools are completely free. Again, the nature of the forensic examination and the goal of the investigation will determine the most appropriate tools to be used.

The collection of tools available to the investigator continues to expand and many tools are regularly updated by their developers to enable them to work with the latest technologies. Furthermore, some tools provide similar functionality but a different user interface, whereas others are unique in the information they provide to the examiner. Against this background it is the task of the computer forensic examiner to judge which tools are the most appropriate for an investigation, bearing in mind the nature of the evidence which needs to be collected and the fact that it may at some stage be presented to a court of law. Without doubt, the growing number of both civil and criminal cases where computer forensic tools play a significant role makes this a fascinating field for all those involved.

Importance Of Data Mining In Today's Business World

What is Data Mining? Well, it can be defined as the process of getting hidden information from the piles of databases for analysis purposes. Data Mining is also known as Knowledge Discovery in Databases (KDD). It is nothing but extraction of data from large databases for some specialized work.

Data Mining is largely used in several applications such as understanding consumer research marketing, product analysis, demand and supply analysis, e-commerce, investment trend in stocks & real estates, telecommunications and so on. Data Mining is based on mathematical algorithm and analytical skills to drive the desired results from the huge database collection.

Data Collection Tools

Data Mining has great importance in today's highly competitive business environment. A new concept of Business Intelligence data mining has evolved now, which is widely used by leading corporate houses to stay ahead of their competitors. Business Intelligence (BI) can help in providing latest information and used for competition analysis, market research, economical trends, consume behavior, industry research, geographical information analysis and so on. Business Intelligence Data Mining helps in decision-making.

Data Mining applications are widely used in direct marketing, health industry, e-commerce, customer relationship management (CRM), FMCG industry, telecommunication industry and financial sector. Data mining is available in various forms like text mining, web mining, audio & video data mining, pictorial data mining, relational databases, and social networks data mining.

Data mining, however, is a crucial process and requires lots of time and patience in collecting desired data due to complexity and of the databases. This could also be possible that you need to look for help from outsourcing companies. These outsourcing companies are specialized in extracting or mining the data, filtering it and then keeping them in order for analysis. Data Mining has been used in different context but is being commonly used for business and organizational needs for analytical purposes

Usually data mining requires lots of manual job such as collecting information, assessing data, using internet to look for more details etc. The second option is to make software that will scan the internet to find relevant details and information. Software option could be the best for data mining as this will save tremendous amount of time and labor. Some of the popular data mining software programs available are Connexor Machines, Free Text Software Technologies, Megaputer Text Analyst, SAS Text Miner, LexiQuest, WordStat, Lextek Profiling Engine.

However, this could be possible that you won't get appropriate software which will be suitable for your work or finding the suitable programmer would also be difficult or they may charge hefty amount for their services. Even if you are using the best software, you will still need human help in completion of projects. In that case, outsourcing data mining job will be advisable.

Inside the Interface: Optimizing Search with Mathematica

Inside the Interface: Optimizing Search with Mathematica Tube. Duration : 3.60 Mins.

As a research analyst at BondDesk Group LLC, Joel Drouillard analyzes the way clients use the company's platform to search for fixed income securities. Recently, he started using Mathematica to go even deeper inside the interface to break down certain properties of searches. Using DatabaseLink, an industrial-strength Mathematica application that allows convenient integration of Mathematica with database management systems, Drouillard can easily retrieve all of BondDesk's click data. Once the data is in Mathematica, he can use the system's large collection of functions for numerical and symbolic computation and data processing to analyze and visualize clients' search behavior. Drouillard says, "I derive an immense amount of benefit from the tools Mathematica offers for mounting structures onto data. Visually, it's a big step forward, too." Drouillard says that with Mathematica's integrated approach to data handling, he can get a clearer picture of search activity on the company's interface and focus more on answering questions and optimizing the system. "One of the biggest advantages that I've derived from switching to Mathematica is its ability to operate in a vector sense or on a set sense rather than having to loop through everything. That's going to be relatively breakthrough in terms of my ability to now answer questions in a matter of minutes as opposed to...hours or days."
