Reasons of Data Loss

Published by admin under Data Recovery

Those who have suffered data loss can actually understand the real essence of data. I think most of the users – whether home user or corporate user – have faced data loss due to various reasons. Those users who haven’t faced any data loss situation may also face it in the future. Computers being complex multi component devices with various moving parts are prone to failures. These failures result in data loss from the hard drive. The most common reasons for data loss from a hard drive are discussed as follows:

Operating system failure

An operating system is system software that enables communication between hardware and software of a computer system. In any case, if an operating system is corrupted, it might lead to data loss. The data loss might occur due to lost clusters, file system corruption, invalid file directories and more.

Virus attacks

A virus has the capability to corrupt or update system files, call operating system internal components and thus take control; it can do more damages that can cause serious data loss. There are in the wild viruses which are active. The others are not that common though more harmful like BIOS viruses, Boot sector viruses etc. These viruses are applications, which do not allow the system programs to work normally. A virus generally enters systems which are connected to a network especially broadband like while downloading something.

Accidental Deletion of files

Data loss might occur due to accidental deletion. Performing Shift and Delete operation or emptying the Recycle Bin leads to deletion of the files. Also, there is always a possibility that any other user intentionally deletes your important data.

Hard Drive failure

Hardware failure is the most common reason for data loss. Below are main reasons for a hard drive failure:

•    Head crash
•    Electrical failure
•    Natural disasters
•    Improper handling

Firmware corruption

A firmware is a software program, which manages all the processes performed by a hard drive. If this software program fails due to any reason, the computer system will not be able to access the data from the hard drive.

In case the data is lost due to operating system failure, accidental or intentional deletion or logical error, then the user needs to use efficient data recovery software. In case of hardware corruption or physical damage of hard drive, the user needs to take help of data recovery services to recover the lost data.

Significant Instructions about the Computer Hard Drive

Published by admin under Data Recovery

Computers have primarily changed the means in which we work, entertain ourselves, plan our trip, and go shopping. We store vast amount of data and information on our computer hard drive.

The storage capacity of hard drive was literally increasing over past 20 years. Modern hard drives come with up to 1 TB of storage capacity. It means you could store all of your music files, computer games, movies, databases, account information and other data on a single hard drive.

You could easily find cheap hard drives for your computer through a number of online stores. There are varying factors to judge while purchasing a hard drive. The only thing, which most people consider is storage capacity. Today hard drives of up to 250 GB storage capacity have become very obvious.

Another important factor is the hard drive speed. It is measured in RPM and you can have it around 7200 RPM. The permanently stored data from the hard drive is brought to main memory for quicker access. Internal hard drives come with high RPM speed as compared to external hard drives.

The most important thing that you should see about the hard drive is the reliability. You should always purchase a hard drive manufactured by an established and experienced company.

Due to moving internal parts, hard drives are very prone to failure. You may face a number of issues with the hard drive like head crash, motor stop, circuit board burning and so forth.

Nevertheless the cause of failure, hard drive failure is never a welcoming situation and it comes with a number of adverse effects. No business can accept the hard drive failure as it causes to the nightmare of data loss.

Some Valuable Learning About Data Recovery

Published by admin under Data Recovery

Today or some other day, hard drive will surely fail and so data recovery requirement is a set future forecast. The most general symptoms that the user sees today are the weird and audible repetitive clicking sounds when the power is supplied to the hard drive, BIOS inability to recognize the hard drive, even a floppy is unable to boot it or a completely dead drive with no power of spinning. The most peculiar incidents responsible for the hard drive failure dilemma are the natural disasters, which require a quality data recovery approach from the reputed source.

If your hard drive is delivering strange noises, then most probably the heads have gone bad and are being unable to read the drive’s information. No data recovery is possible when the magnetic material has got scraped off from the platter’s surface. If you continue running the head drive after a head crash, it could destroy the written data with the scratching act. Just indulge in the contract of reliable data recovery service, where your failed hard drive will be opened in the Clean Room environment and affected heads will be replaced. An expert data recovery engineer will perform some meticulous tasks to again set the heads into a perfect alignment and make it operable to read out data.

Hard drives are available with the incredible spinning speed, which on one side offer a great data accessing power, while slowly creates data loss situation on the other side. Electrical issues are also the major concerns due to natural reasons like lightening, manufacturing reasons like poor power supplies and accidental reasons like power outages. Be it a Maxtor, Quantum or Western Digital hard drives, a burnt out of a single chip can make the hard drive to stop.

A common misconception says that the users believe it is easy to handle electrical problems by just replacing the board. The user may say “Data recovery is a fix as I’ll swap the failed electric board with the one of the same hard drive model”. But, let me clear you a hidden fact that under a same hard drive model, there may exist many electric board revisions and this fact makes board swapping a complex job.

Data recovery engineers undergo a stepwise task. Upon receiving the failed hard drive, if it is feasible, then they make the hard drive operational and make a sector by sector copy of data to avoid further mistakes. This frees the data recovery experts to have some changes on data and test some data recovery utilities, which can be otherwise harmful for the original data.

Due to the daily adding features, hard drives are becoming threatening. High competition, less margins and zest of delivering fast are making the inexpensive hard drives and fallible hard drives as a result. But parallel attempts of data recovery experts are in continuous move to separate off the dreadful data loss situations.

Data recovery experts of Stellar Information Systems Limited devote time, endeavors and skills to extract the lost data. So go for it and through the Class 100 Clean Room availed data recovery services, get the valuable data recovery done. Here, you will find each data recovery solution.

What to Do When BIOS Does Not Recognize the Hard Drive?

Published by admin under Data Recovery

During POST or Power On Self Test, computer BIOS attempts to get information regarding all of the devices attached to your computer system. After examining the processor and primary memory (RAM), it checks for the devices like hard drive, CD ROM etc and shows them with messages on screen like ‘Found Primary Master’ and ‘detecting IDE drives’ etc.

-> POST (Power On Self Test) is the first thing done by BIOS when your computer first boots up. POST is an in-built diagnostic program, which examines the hardware of your computer system to make sure that everything is available and working properly.

Many times, the BIOS of your computer just declines to recognize the hard drive, basically makes it unusable- there is no way in which your operating system will recognize the hard drive if BIOS can not. Let’s observe why all this happens.

The most frequent reason of this problem is a badly connected or loose data cable. You should first ensure that data cable is properly plugged in, both into the motherboard as well as the hard drive.

The same thing goes for the power cable, so you should check it as well. You should also make sure that red lines on data cable and the power cable are contiguous to one another.

Once you have ruled out the cable problems, you need to check out the jumper settings on hard drives. If two hard drives are attached to a port, ensure that one is set as masters and other as slave.

Next, ensure that the hard drive controllers on motherboard are not disabled. These hard drive controllers control the IDE devices and without them BIOS could not detect the hard drives.

If any of the above mentioned methods does not work, you need to search for a data recovery expert to cure your hard drive. It seems that hard drive has some internal problems, which can not be cured without opening it. And you are not recommended to open your hard drive at your own.

Data recovery experts are highly qualified and trained professionals, who know all ins and outs of the hard drive and are able to fix most of the physical hard drive problems. To ensure absolute and safe data recovery, always go for the experienced and reliable data recovery company.

Stellar Information Systems Limited is the most trustworthy and leading data Recovery Company, having more than 15 years of rich experience. Stellar’s personalized data recovery services is offered by highly trained data recovery specialists through Class 100 Clean Rooms.

Why Can’t a Novice Perform Physical Data Recovery?

Published by admin under Data Recovery

Novice user can’t perform data recovery from the physically failed hard drive, that’s a fact and the subsequent details will support this statement. However, the logically failed drive is under control of data recovery by a layman as data recovery software don’t offer any sort of operational difficulty for the user. But, the rule gets totally flipped, when it comes to physical data recovery. Complexity and technicality that’s what a physically failed drive asks for data recovery.

Data recovery service is an intricate part of science and this has been analyzed that after years of regular efforts, this has sprouted as an individual Information technology industry, which entirely moves around different ways of data recovery. Now the ways, in which a drive gets failed and affects which are drawn on, are different from case to case and so no two data recovery methods complement each other exactly. The natural emergencies such as flood, fire, earthquake and others have heavy impacts, which may even render the drive unrecoverable, while, a mere component failure is less threatening to the data.

Data recovery services is available for all storage media like hard drives, CDs, DVDs, floppy disks etc., but this has been found that majority of users experiment their data recovery techniques only on hard drives. This may be due to the fact that hard drives appear sturdier than any other. Moreover, there are more physical components to play. But, let me clear to you that as soon as you open your hard drive, its sensitive facet steps in.

The internals of hard drive are extremely fragile to the dirt like particles of environment and the suitable protection can only be given, when treated under Clean Room surroundings. Physical data recovery may be followed by logical data recovery, but if it can be successfully repaired, no such recovery is required.

Hard drive structure is complex, comprising of bundle of components, which may appear tricky to understand for a novice. Read/write head, circuit board, actuator arm, platters, shaft, motor and list goes on, these parts are pretty complicated in their design, but a data recovery expert knows how to deal. Practices, like freezing the drive, shaking it vibrantly and trying to run it, are venomous to the data.

Data recovery is not what you get from the set of books, but it’s the practical application of comprehensive and technically built tools and techniques. So, this is completely a fantasy that a non-expert person can come out with complete success. But for data recovery companies, this is possible and hence you should choose the correct company for getting your data back.

At Stellar Information Systems Limited, you would find the maximum data recovery chances as of the well-built tools and procedures. Class 100 Clean Rooms add to the power and data recovery experts make it feasible with the possible results. Stellar has a solution of each data loss circumstance.

Opting The Correct Hard Disk Recovery Solution

Published by admin under Data Recovery

Need of hard disk recovery is a possibility for everyone, who is engaged in some type of deal with computers. May be not right now, but this evil can empower the computer owner anytime. Even the precautions like backup may not prove fruitful to yield complete data and then hard disk recovery, which actually picks your pockets, is the only defense against critical situations.

Due to reasons like comparatively lower prices, easy to use, less time consuming etc., the hard disk recovery software may appear as first line of defense. Actually they are, but not in the cases like head crash, natural disaster strike or any other in which the physical data loss is there.

Hard disk recovery software address basic problems of data loss like retrieving deleted file due to owner’s mistake or virus attack, recovering data after disk formatting and so on. Advanced software are competent to avail data recovery after file system damage. But, data recovery surety is not with each one in the market as many of them come with the limited success.

Not all hard disk recovery software are the answers of each logical data loss problem, some of them are designed to resolve only file deletion issues. So, differentiate amongst them before coming to any decision. The manufacturer’s website will prove a good deal for the same.

On the other hand, when physical crash is there, hard disk recovery service opens its doors. When the damaged disk components start bothering you, benefit hard disk recovery with the reliable data recovery tools of technicians. The more serious incidents require top-notch quality techniques to recover, which only an experienced technician can offer. If the company has devised Clean Rooms, this adds to the power of data recovery and actually is a must to have assets to provide maximum data recovery.

Hard disk recovery technicians see the data loss problem from different angles which make data recovery hopeful.

Do It Yourself Data Recovery- Last Resort Technologies

Published by admin under Data Recovery

Is Do It Yourself data recovery possible in case of physical damage? The probable answer of this question is no, unless you do not have sound technical skills and experience in handling computer hardware issues. However, there are some thing you could attempt to perform Do It Yourself data recovery from a failed hard drive.

You should always bear in mind that none of the below mentioned methods are a good primary alternative. If your data are extremely sensitive and highly important from business point of view, you should never attempt these methods, as they may further damage the drive.

Data recovery preparation

To get ready for data recovery, you will need a healthy computer and will have to connect your affected hard drive to it. The healthy drive should have enough space to store the data recovered from the failed hard drive.

The secondary hard disk can also be the internal hard drive of your computer. You should always know that there are hazards involved with attaching the failed hard drive to any of the healthy computer.

Solitary Chance

In some cases, you will possibly can get chance to access your hard drive and data after attaching to the healthy computer. If you are fortunate and are able to access the data, just save it to another hard drive.

Logical Board swapping

It consists of removing the failed circuit board from the hard drive and replacing it with the new one of any working hard drive.

It is not sure that this process will give you the desired results. If the process becomes unsuccessful, you may fall in grave situations and your hard drive might become irreparable.

Repeated booting

Why Does Hard Disk Crash Out?

Published by admin under Data Recovery

When you first bought the hard disk, the provider assured you about its reliability and data maintenance capacity, but what happened suddenly that it broke and you needed data recovery. Was it your harsh behave or some other hidden fact from manufacturer’s side? Let’s discover it here.

No doubt, computer hard drives offer data storage for long run, but there is a limited shelf life. The main motive behind its creation was to ease the users with less susceptibility, but the idea flawed when some imperfect engineering concepts rose and became responsible for hard drive failure. Most of these faults have not yet been covered with the recent developments, though regular efforts are being put in.

Initially, there were lots of concepts which merged to give a hard disk and then the further developments, at regular intervals, enhanced its power. The idea was to make a rigid piece, which is stiff with the metal casing, air-tight to avoid dust particles and other contaminants, spins so as to give better data access etc. But, due to some unconsidered facts, the concept suffered drawbacks which ultimately lead to hard drive failure.

In contrary to the external appearance, the internals of the hard drive are very sensitive to even the high heat impacts. Hard disk stores data on the magnetically coated platters, which memorize data with the alignments of the magnetic particles. Read/write head senses this alignment and lets you access the data. This head is suspended at about negligible height that even a dust particles is too big to enter in. But, if it enters, head gets crashed. Moreover, the head accesses data in the random fashion and at a high pace, which can in turn bring disasters to the hard drive. The actuator arm which suspends it can become highly stressed with these swiftly performed data accessing operations and may burst out with the malfunction.

The high-spinning platters can become so indulged in their work that can generate extensive heat, causing harms to the internals. The scratches or the disturbance in magnetic alignments can separate your data forever as data recovery declares ‘no recovery’ when the platter coating has got destroyed.

The electric components of the hard drive like controller and circuit board are prone to the electrical damage which becomes another cause for the hard drive to fail. The electric surge can destroy the circuitry.

All these factors, either individually or as the combination can cause data loss for which data recovery is the cure. But, in any of the case, you should not continue working with the system and perform any operation like freezing or opening the hard drive which can damage it further. Seek data recovery professional help and assist data surviving.

Data recovery service is not an ordinary process, but instead is the specialized and skilled work of the professionals. Data recovery associates undergo a precise treatment in the sterilized environment with the high-tech tools and procedures.

However, the best data recovery help is given at Stellar Information Systems Limited. This is a company with the proven track record of offering data recovery services in each physical crash case. Class 100 Clean Rooms and the set of high-ending tools and procedures make Stellar’s data recovery service as an effective measure.
