The sudden loss of precious data is an incident which many people fear will happen, and then they kick themselves when it finally does. RAID systems have a reputation for being particularly tricky to recover, and so the process of RAID data recovery is a highly particular procedure which can be challenging for non-literate computer users to say the least. It is said that what we fear is fear itself, and in this case, fear of the unknown makes many PC owners shake in their boots. So, why does this happen and what can we do to salvage what is left of our data?
Data Recovery can occur for various reasons. These can include a vicious virus take-over, secondary devices damage, or just plain old kamikaze computer crashes. When your PC decides that today will be the day that it will lose that all important file, aptly titled "NB," one has to accept the fact that data is lost and recovery resuscitation is needed in order to salvage your valuable information
In this respect, RAID is known as being one of the most complex systems to recover. This is due to the fact that they contain a high level of input/output capabilities. With the right expertise and technical equipment, it is possible that RAID data can be successfully recovered and that you may, once again, have your computer back to its full functioning potential. One of the most vital keys to RAID data recovery is the ability to problem solve and return results within a limited time frame. One needs particular tools and primary supplies in order to calculate the recovery of data. In the case of RAID, recovery specialists are preferred as opposed to DIY software owing to the possible complications, as well as the high risk of this type of data recovery. In most cases, RAID data recovery involves the restoration of certain components that are damaged and need to be professionally repaired. Enter specialists.
For many of us who fear the act of data recovery, it is suggested that one may decide to leave it to the professionals, where the risk of data loss mayhem will not occur. When recovering your RAID data is vital to your job, school grades or any other significant life-or-death situation, RAID data recovery services can save the day and return to you what is so right fully yours.

RAID 50 Failure and Data Recovery Service
In RAID 50 implementation, large arrays are formed by combining parity and block striping of RAID 5 with simple block striping of RAID 0. It is basically a RAID 0 array that is striped across RAID 5 elements and requires minimum of 6 drives to configure. A RAID 50 array might fail, rendering your data inaccessible. In such situations, you need to replace the array and call Data Recovery Service experts to recover lost data efficiently.
An Example
Generally, RAID 50 proves to be more fault-tolerant than its counterpart RAID 05, but it can fail. To illustrate, consider that you use three collections of RAID 5 sets, each with storage capacity of 180 GB. These sets are striped together so that to make total array of capacity 540 GB.
In the setup described above, the array will remain intact if one drive from each of the RAID 5 sets fail and will not cause any data loss. But until the failed drive is replaced, the entire array remains at single point of failure. It means that after the first drive failure, the remaining drives should not fail to prevent array failure. If any of the remaining drives fail, the array will fail.
The fault tolerance level of the array also depends on how the array is configured. If you construct three RAID 5 sets containing seven drives each, it will provide you good capacity, but provide fault-tolerance of up to three drives. On the other hand, an array with seven RAID 5 sets containing three drives each will provide lower storage capacity but high fault tolerance of up to seven drives. A reliable construction could be an array with three RAID 5 sets containing six drives each and a hot space that could provide immediate rebuilding of array on failure.
RAID 50 Recovery

Professional RAID Data Recovery Services Are Best When Data Systems Fail
As systems have grown and become more sophisticated, everyone from large companies and small businesses to home users have moved from a single hard drive for storing their data to the ever-more speedy and advanced RAID (Redundant Array of Independent Disks) systems on the market. Although RAID systems are now larger, more robust and have a far greater range of graphic and sound storage options, their complexity means that crashes can be more catastrophic than previously.
The good news is that RAID data recovery is not usually a serious problem - provided you engage the services of a reliable and professional RAID data recovery service. The failure of such data systems needs to be treated as a top priority and a good service will ensure that the problem is diagnosed as quickly as possible, to determine whether it can be dealt with in their computer lab or on site.
If RAID data recovery needs to take place at the lab, technicians will engage all media that is still accessible in order to make a raw copy of its data and place it on to new media. It will then be possible to deduce the precise nature of the data loss. During these tests the data recovery service will also run tests on the systems components to determine if there is any physical damage present, and to what extent.
RAID data recovery often requires the replacement of broken components in the sterile environment of a computer lab, alongside the use of specially-constructed software and hardware devices to recreate the raw data image, through close examination of the failed servers lower-level data sectors. It is essential for technicians to work out which volumes of data are "striped" across multiple drives on the RAID system and then to implement the correct solutions to file system structures, allowing access to the data.
Servers with a large number of drives are carefully "destriped" and placed in new media, enabling repairs to the file system and the extraction of missing data files. Upon the successful recovery of data, a good service will also create new file lists and check the validity of all the information.

Emergency Data Recovery Plan That Works Every Time
It is always in your best interest to keep an emergency data recovery plan in place. It basically involves laying out detailed instructions manual for the process of retrieving inaccessible or deleted data from a hard drive. So that if situation arise you need not panic and simply proceed with the recovery procedure.
Hard disk crashes are common due to several reasons. Data can be lost due to regular wear and tear, physical failures, software errors, computer viruses, malicious software, visiting affected sites or by simply opening your email. Other threats like fire and electrical are also not uncommon.
It is possible to completely recover your important files if you follow a set procedure from the beginning. If a file is deleted, your operating system merely deletes the address of the file from memory. The actual file remains intact on the disk till you run shortage of space. If you are running shortage of space the old files that are deleted are replaced by new files.
File Allocation Table (FAT) maintains details of all the files on the hard drive at any point of time. You data recovery software scans through this table to locate deleted files. If you start the standard procedure of recovery immediately you can recover the lost files 99% of times.
Though the freeware software available can perform this task easily but if the lost files are of critical importance it is highly recommended that you immediately shut down the system and seek professional help from data recovery firms. As a simple mistake and damage the files and make it permanently irrecoverable.
It is always a good practice to take regular backups of your important files. Try to save them on different computers and on different media like CDs and DVDs. This simple care save you huge data recovery costs from professional recoveries.

Warning Signs of a Hard Drive Crash
A hard drive crash is not the worst thing that could happen to a computer. It is when the drive crash brings all your important files to oblivion. Before it happens, make sure that you back up all your important files. Also, it would be wise to be observant of the early signs of a hard drive crash.
Here are some of the warning signs of a hard drive crash:
Blue Screen of Death
One of the most distinguishing characters of a crashing drive is when you see the "Blue Screen of Death" even once. It is a prelude to a more terrifying scenario- a hard drive crash. BSOD's (Blue Screen of Death) occur when there is a serious problem with either software or hardware. It could be caused by anything from a corrupt and dysfunctional program, software incompatibility, registry errors, and damaged drive, among many others. If you see the BSOD even once, prepare to backup all your important data. You're never sure of when the drive would crash.
Clicking Grinding Noises from the Hard Drive
Usually, a hard drive sounds smoothly under normal circumstances. When you hear the drive clicking or grinding, it means that the spinning of the Read/Write heads are very close to the magnetic platters. This is a bad warning sign of a crashing drive.
Computer Reboots on its own
On typical cases, the computer could only do what it was commanded to do. It wouldn't shut down on its own. But in some cases, it happens that the computer reboots on its own. This could be because of many different factors that are mostly hardware issues like an overheating processor due to very low ventilation. In some cases, it's disk drive issue.
Windows Freezes
Sometimes, it happens that the windows suddenly freezes. It doesn't do a single command, like exit or minimize windows. Your mouse and keyboard might not work, too. The solution for this is to restart the computer, and most of the time it solves the problem. A Window freezing is just a minor sign of a drive crash.
"Hard Drive is not formatted"
In rare cases, an error message displays "Hard drive is not formatted". What you can do is try restarting the computer, it may solve the problem. In case that you encounter this error message, never try to reformat your drive because this will surely erase all your files, including your operating system.
Error loading Operating System/ Missing Operating System
This is a bad sign that your hard drive is thread away to crashing. In fact, I would say that it's a drive crash, but with professional help, your files could still be recovered.
In instances when you encountered these warning signs of a drive crash, be smart and back up all your important files. You can also try fixing windows using Scandisk or try to repair windows using available software utilities.

Online Backup Services Making Data Recovery Even Easier
Are you worried about losing valuable data stored on your pc or mac? Do you have documents, photos and music you just can't afford to lose? Then it maybe time for you to consider an online backup solution and here is why.
We all use computers everyday and store valuable information on them from family photos, music, personal and business documents. While this data is stored on our computer, we never think we'll lose it almost like our computers are immortal, however our computers are prone to losing this information permanently if the data is not backed up to other media like tapes, CD or DVD. Our computers store information on the internal hard drive which is a spinning magnetic disc. Unfortunately, sometimes our computer hard drives crash, become corrupted and our information can be lost forever.
If your computer hard drive become corrupted and your data is lost, you can have a local data recovery expert look at the drive using special data recovery software to see if the data is in fact recoverable. Often it can be but the costs associated with data recovery experts can be in the thousands of dollars depending on how much data needs to be recovered.
With the advancement in computer technology, we now have available as easier solution and one that provides even more features than just data recovery. Online backup services, provide numerous features including data backup, file sharing and syncing, mobile phone access and even version control all in one low cost package. Most of online backup services come with a number of plans to choose so you can easily find an affordable plan to suit your budget and also your needs.

Hard Drive Recovery Services Do They Really Work?
We all know that data recovery services are not necessary when things are working great on your server. It is only a needed when a problem with your hard drive fails and you cannot retrieve your data. The files we keep on our discs are vital to our very existence. When we lose those files we feel lost. The hard drives are sometimes are still have warranty from the manufactures, but the problem is when the hard drive fails you cannot retrieve data from it.
You may be able to fix your disc yourself, but when there is physical damage to the disk you may not be able to fix it. On YouTube they have teaching videos on how to fix your hard drives and tutorials on how-to do-it-yourself. In some cases it is all you need to fix it yourself. Generally, there is some 10-year-old geek kid that shows you how to fix your hard drive in 3 seconds or less. Like most of us who are not computer savvy it is great to see how we can fix our own computers quickly.
Many of us who are not computer savvy will have to send our hard drive to a data recovery service company. There are many companies out there who specialize in data recovery corruption on your disk. When the problem is human or mechanical failure it is always possible to recover your lost data that has been corrupted on your hard drive. I will mention a few of these companies like DTI, HDRG, and TMD. These companies have clean rooms and have the capabilities of retrieving hard drive information quickly and easily.
They have the an IT staff who are up-to-date on technical specs for manufactures and have a database of model numbers and serial numbers about your disk. If you have a hard disk problems using these data recovery service companies can be your only salvation in retrieving your lost data. The great benefit of these companies is that if they cannot retrieve your data, and then they will not charge you for their services.
