Hard Drive Data Recovery

RAID stands for Redundant Array of Inexpensive Disks. This technology is typically a reliable storage option for computer users and has better read/write speeds vs. single drive servers. If a drive fails, they also have better fault tolerance and usually, superior data protection. However, there are times when you could be faced with a data raid recovery situation.

Why are these systems so ideal for data protection? They allow data to be written to multiple hard disk drives so that a failure of any one drive in the array does not result in the loss of any data. As a result, many businesses rely on them to handle critical data such as financial information and business system data such as email, database application data, etc. Although they are typically safer than other storage media, these systems are still susceptible to total system failures. How? Multiple drives can experience simultaneous problems. And the problem with this type of data loss issue? The business can come to a screeching halt because data stored on the RAID array is usually business critical. That's a big problem.

History

The RAID idea was developed at the UC Berkeley by researchers, David A. Patterson, Garth Gibson, and Randy H. Katz. They were working to produce prototypes of five levels of these types of storage systems. Their ideas laid the groundwork and formed the genesis of today's complex RAID storage systems.

What were the researchers design goals? To provide performance improvements, storage reliability and recovery, and scalability. The redundancy concept employed in these types of systems is special. It helps to recover if one drive should fail within the system. But no worries - if one drive is off-line, RAID controller cards can continue to read and write data

Levels

Level 0 provides what is called data striping. This essentially spreads out blocks of each file across multiple disks, but no redundancy. This is great for performance; however, it's weak on delivering fault tolerance. With the collection of drives in a RAID Level 0, data can be accessed from multiple drives in parallel. Why? This type of array has data organized in stripes across the multiple drives,

Level 1 provides an ingenious idea - disk mirroring. With this concept, data is written to two duplicate disks at the same time. If one of the disk drives fails, the system can switch to the other disk without any loss of data or service. RAID 1 enhances read performance, but the improved performance and fault tolerance are at the expense of available capacity in the drives used.

Of all the levels. level 5 is the most frequently implemented. It provides data striping at the byte level and also stripe error correction information which dramatically improves performance and helps to recover any lost data when a single drive fails.

Data recovery providers can fix broken RAIDs, don't allow your IT team to fix the system by relying on the original configuration, or documented administrative procedures. Also, don't force a RAID controller into a particular configuration. This could result in even greater damage to your data. Data recovery specialists typically figure out the RAID manually by looking at every sector of data across all of the drives in a system to put it back together. The original configuration may have flaws in it. Knowing that, they rebuild distributed data blocks, and drive order and data symmetry, until it is restored. Specialists can even work on these types of systems if the original hard drive has failed by reconstructing the RAID virtually. An advantage of data raid recovery is its ability to get back the most recent files versus the most recent backups. This is important to know because RAIDs often store the highest value data.

Data recovery services are in great demand nowadays. More and more people have a computer as their working tool. We are more or less forced to start working and knowing computers.

But what happens when one morning, when trying to open your computer, it simply doesn't boot? It doesn't seem to be able to recognize your hard disk drive. Desperate and full of hope, you take the hard disk and insert it into your friend's computer. Unfortunately, it's the same story. And you had all your work on that hard drive. Work which you forgot to burn on a cd or dvd. Now what?

It's easy. You call a data recovery company. On your friend's computer (you can't use yours, remember?) search the internet for available data recovery companies in your area. You will probably find a phone number at which you will be able to call. You will be asked a few questions, so before you call, you need to know some technical details.

The first one is the model of your hard disk. You need to take a look at it and see the company which produced it, as well as the model. If you knew how to get it out of the computer, you will surely know that. If your friend did it though, just take a look at it or check the documentations which came with the computer.

Then, you will have to tell the data recovery assistant what operating system you were using. Now, because I don't want to advertise, your operating system's name is what appears when your computer starts, and it often has the name of a component of your house. You know what I'm talking about.

Finally, you will need to provide the names and types of the files that you really want recovered. You see, each file has a name and an extension. For example, text files created with notepad have the .txt extension. If you are working with the almighty program created by the company responsible for the operating system, those files have .doc extension.

When you provide the company with your hard drive, an evaluation is made which will tell you the amount of damage your hard drive has sustained. Taking that into consideration, a priced is set for the recovery of your losses.

Without getting into more technical details, it must be said that having your data recovered can be a life saver. It can be your work for a period of time which is at stake. Although, it must be said, when all your work is centered around one computer, you really need to create a back-up option.

Imagine the first scenario (the one in which you lose all your data) and a scenario in which you simply take a cd from your drawer. The miraculous cd has all your work, because you are very careful and you save your work from time to time on it. Now, tell me, isn't that the best data recovery method?

With the advent of the computer age, our generation is inevitably linked with computer technology. Whether we like it or not, computers loom everywhere. They run and facilitate every industry. Be it in the train we take to go to work, the credit card we charged our payments with, atm cards, banks, electric power facilities, plants, etc. - name it and computer will come to mind.

It is imperative then that we take all necessary steps to ensure that computer data are well-protected. It is a well-known fact that several threats to our computer systems exist. Take for example the infamous i-love-you virus. Released on the eve of Valentines Day, this virus wreaked havoc to the worlds most complex, protected and highly developed computer systems. Banks, companies even the organizations like UN, Pentagon and FBI proved no match against its venom. And that is just one virus. A number of disasters stemming from other viruses could also plague the computer. Added to this are the threats of natural disaster, electro-magnetic failures, and computer crimes could befall. Virus though is not the number one reason for hard disk failure. Surprisingly, it is the avoidable user error.

For any computer user, the word hard disk failure is a nightmare! No one would want to be in this position. The amount of time, money and effort spent in the resulting file recovery is simply not worth it. To prevent this situation, one of the most important points every computer user should bear in mind then is to always back up computer data.

If one failed to adopt preventive measures through back-up files, hard drive recovery would be the next best option. Data recovery is another necessary tool to counter computer threats. Data recovery, simply put, is regaining damaged or corrupted files. But the amount of effort behind this endeavor cannot be branded as simple. Data recovery is a very time-consuming process and the cost is prohibitive. And it is necessary to approach the right hard disk recovery experts for this task. Data recovery cannot be left to chance.

If the problem is simple deletion of files, hard drive recovery software could be used. The cost is minimal. But hard drive recovery software merely goes through the file system and offer to recover deleted files. Data recovery softwares use is limited. The hard drive recovery software is not effective in all cases though. In more complicated cases like total hard disk failure, it would be wise to solicit help from hard disk recovery experts.

Hard disk recovery experts have different techniques in addressing hard disk failure. They could use off-the-shelf hard drive recovery software. Or, software that is custom-made. Going to hard disk recovery experts though, as a last resort, will not guarantee file recovery. Sometimes, hard drive recovery for total hard disk failure is a lost cause. Data recovery is not always possible. It is wise then to prepare for the worst. Before hard drive recovery occurs, preventive measures must be adopted.

If more people would commit time and resources to ensuring good back-up, hard drive recovery would have been unnecessary.

With several companies and businesses relying on computers for storing their reports, files, and information sheets, protecting systems is no longer enough to emerge at the top of the industry. Data recovery is the latest in counteracting loss of data whether its due to bad weather, hardware failure, malicious intent, or human failure.

Before, much confusion and inconsistencies in information about data loss made data loss and data recovery the most misunderstood concept in the computer industry. Because of this, many users and experts often consider lost data as permanently damaged with no way of retrieving it. But now, with the advent of new facts on data recovery and loss, computer whiz and experts are now focusing more on restoring data into the systems as a new way of overcoming data loss or corruption.

The discovery of the concept of file retrieval led to several data recovery experts offering their online services. The services offered by these experts range from hard drive recovery, software or program retrieval, mailbox file retrieval, and more. Data recovery services are practically endless with numerous experts coming up with more and more ways of recovering important files and programs that are lost.

So what exactly is data recovery?

Data recovery, according to the word sleuths and recovery experts, is the process of salvaging of deleted or inaccessible data stored on damaged media like magnetic disks and computer hard drives, optical devices, and tape cartridges. A large number of file retrieval software and data recovery service is designed to help users retrieve their files at the event of a computer crash or viral infection.

How does data recovery work?

The first step of the process of data recovery service usually involves evaluation where the initial analysis of the extent of the data lost is determined. After the prognosis, the data recovery experts and technicians would then proceed in cloning or copying the media and queuing it into their systems. The actual file retrieval process occurs when the technicians secure and extract the data from the copy of the damaged media.

Hardware and Software Teams

A damaged media has the data locked within it and it is the job of highly experienced hardware and software engineers to unlock it. These two teams of experts work very closely together throughout the project, combining all their experiences in their respective fields to solve the problem quickly and surely.

For safety measures, hardware engineers access as much of the disk as they can to produce the copy which they then share with the software specialists. The bulk of the file retrieval process lies on the software team as they are the ones who do the actual extraction using complicated software programs designed especially for recovery work. The ensuing data are then filed and written onto a new, undamaged media.

Data recovery has become an essential part of the computer industry. Many companies offering data recovery service invest heavily on research and development to ensure efficiency in the whole spectrum of data recovery.

Hard drive recovery is an important tool to combat data loss. Many threats to computers could lessen data accessibility. It could be as simple as file deletion. Or, as catastrophic as hard disk failure. Whatever it may be, the necessity for hard drive recovery in both circumstances is foremost.

The number one rule in hard disk recovery is if you accidentally delete files; do not to write anything more to the hard drive. This data recovery rule applies in every circumstance. If you delete a partition, do not create another. Leave it blank instead. If you happen to delete files in the recycle bin which you consider important, do not save anything to the drive. This data recovery suggestion may sound puzzling but the reason for this is that hard disk do not delete anything, whether data or partition. When you delete a file, the data is still in the drive. What happened is that the operating system marks the physical area of the disc as available for future use while leaving the original data there. The computer hides the file so you can no longer get to it. Its still there until a new data is written over it. So if you save another data to the drive, it will consider files marked deleted as empty space and copy over them. If that happens, then the deleted data is in trouble in turn affecting hard disk recovery procedures.

The same rule applies to partition. If there is no partition information, the operating system cannot read any data. But that does not mean that the data is not there. Only, you cant read it. If you have just one partition and the operating system does not function, the best option is to transfer the drive to another computer.

Transferring the drive to another computer prevents the drive from being accidentally written over and potentially allows you to access the data in turn implement hard drive recovery by using Windows Explorer. If you erased essential operating system files, the drive can still be read from another operating system. If you cannot transfer the hard disk, resist the temptation of re-installing the operating system.

The simplest method to hard disk recovery with single partition with damaged operating system is to boot your computer with DOS boot disk. Then use a DOS compatible file recovery program.

Installing your had drive into another computer or putting a new drive with separate operating system into your current machine will enable you to attempt access to you data through Windows File Explorer. And you can safely try data recovery since you have a completely separate hard drive. Freeware hard disk recovery programs are also available to facilitate the task of recovery. One can choose from various options.

The hard drive recovery tools suggested above are meant to facilitate hard drive recovery efforts. If all else fails, a hard drive recovery service could be the last option. Hard drive recovery service could be much more expensive but data saved could be worth it.

Every data recovery plan starts with a corporate policy, which would outline what comprises a critical system.

Whatever constitutes a critical system, the need to identify it decides what action you need to take to prevent massive system failures and ensure an efficient data recovery process.

Once these policies have been specified and agreed upon, they must be turned into actions by the corporate IT department.

The first step of the process usually involves evaluation where the initial analysis of the extent of the data lost is determined. After the prognosis, the experts and technicians would then proceed in cloning or copying the media and queuing it into their systems. The actual data recovery process occurs when the technicians secure and extract the data from the copy of the damaged media.

For many companies, the first step of disaster recovery and data recovery is having a back up plan.

Back up processes are a cycle that usually includes supplementary back ups daily, full back ups weekly, monthly, quarterly, and annually. Many more ways are available and whatever you choose, you must make sure that the maximum amount of data lost is equivalent to that of data created or stored in a single day. This way, the whole recovery process will be simplified and much easier to manage.

Aside from back ups, there is also a need to ensure protraction of equipment and the ability to read and run media over time. The safest way to do this is to keep continuous updates on the type of media used for storing back ups. If the backup media cannot be read because the only hardware capable of doing so is too outmoded or is no longer in production, then your disaster recovery are completely laid to waste.

Another reason why there is a need for continuance in back up media is the assurance that total recovery is possible with a complete back up system and disaster recovery policy. Time is also another factor. Disaster recovery and data recovery strategies may take longer if incremental back ups are done sporadically.

If you are to restore systems quickly, you will need offsite hardware that is as close in specifications to your existing equipment as possible. These key back up servers will minimize the time it takes to do a complete recovery process. Again, continuous updates in these servers are fundamental to the speed and efficiency of the data recovery process.

Having a disaster recovery plan is an essential part of your business. It is precisely for this reason that you not only need to have a data recovery strategy but also that these plans are regularly tested to make sure that theyre good enough. When you prove that your data recovery and disaster recovery strategies really do work, then that is the time for you to say that you have a valid data recovery plan.

How can I backup and restore my desktop?

Data loss is inevitable when you don't have a good backup solution in place. What can cause this data loss?

- Hard drive crashes
- Software malfunction
- Even operator error

Have you ever heard of a software malfunction happening? It happens even on the most secure and pristine computers in the world. Think about putting a computer backup system in place if you want to prevent costly downtime, data and software loss.

Next we are going to discover what your backup options are, what data should be backed up, what types of backup devices can be used, a restore strategy, and why testing is important.

The objective of a backup and recovery plan is to minimize the damage caused by a computer crash, and preserve your valuable software and data. Restoring your computer to its normal operating condition will be your first concern when facing this type of issue.

A common plan used by many computer users is to store all program installation disks including the operating system clearly labeled with serial numbers and necessary installation info in a safe place. As part of your backup program regularly back up your valuable data to another type of storage device other than your main drive where your operating system resides.

This secondary storage can be a CD, DVD, an extra hard drive mounted in your personal computer, or even a hard drive mounted in a hard drive enclosure connected by a USB cable. In the event of a hard drive crash or system failure, you could mount a replacement hard drive and reinstall your operating system with the disks you have already stored in a safe place. Programs could be added all at once or on as needed basis.

The importance of daily backups now becomes apparent. It is of most importance and sometimes obvious to make sure your critical data is included in your daily backup plan. If it is not backed up and it is lost, it is lost forever. You would be surprised how many people forget this important little statement.

When considering your backup and restore options you will need to determine the method of the backup and restore. Another option would be to completely backup the whole system by means of an Image backup. This would include a complete computer system backup bit by bit. Then when the inevitable happens and your system crashes you can restore your computer to the exact state it was at the time of the image backup.

If you value your computer software and data you should implement a computer backup solution that meets your needs. Prepare for the day when you could lose it all because of a computer malfunction. You should be considering a computer backup plan before anything major occurs. Now get going and make something happen.
