How to Recover Data from Damaged RAIDS

If you are suspecting some discrepancies in your RAID network, don’t neglect it cause it might be too late for you to react when your all important business data starts vanishing into thin air. Do not be under the erroneous assumption that a RAID fault can be set right by employing a software. Its not possible neither is it feasible.

RAID is a complicated network, which requires expert handling, and no layman with limited technical knowledge should try their hands at reconfiguring the RAID if any of the hard drives in the array suffer failures on the event of a virus attack, accidental deletion, system crash, corruption, hardware failure or a natural catastrophe like fire and floods.

RAIDS attached to servers are a boon to any organization but its maintenance is even more crucial and painstaking, as it involves not just one hard drive but multiple hard drives depending on the capacity and requirement. RAID is equipped with some of the most advanced features that facilitate data distribution, backup and storing process.

Mirroring, Striping, parity check are some of the unique features that makes RAID unparalleled in its given domain but when data loss situations occur due to disruptions in the RAID Array, hard drive recovery is very complex and technically taxing. The very definition of RAID spells out the fact that it encompasses in its fold all the devices that contribute towards the data’s safety and security right from its initiation to its completion.

RAID or Redundant Array of Independent Disks is a subsystem that is generally linked to a server or a computer for enhancing the performance or providing fault tolerance or both. RAID is available in different levels and requires hard drives and RAID disk controllers whose numbers vary and are commensurate with the level of the RAID that is opted for.

RAID servicing requires specialized personnel who have received express training in the given field and are in a position to handle the complex procedure as they are backed by rich in class infrastructure and inventories. Clean Room facility is a must if you are opting for a service provider.

Stellar Data Recovery Inc., a pioneer data recovery service provider specializing in data recovery and data protection services has emerged as the market leader as far as recovering data from servers attached with RAID is concerned.


Equipped with trained and expert data recovery professionals and an excellent Clean room facility, Stellar can effectively salvage your lost data from any RAID level mounted on any hard drive (any type, make or model) by applying top-notch proprietary tools and techniques.

It is of utmost importance to observe certain rules before sending the corrupt hard drive to the data service Lab.

Please refrain from running any volume repair or defragmenter utility if you are sensing a bad drive

Before labelling the drives with their position in a RAID array make sure that you have a substancial backup supporting the hardware or software changes.
Turn off the system immediately if grinding or cracking sounds are coming from the drive.

Power surges cause the gravest damages to a RAID Array and lead to file system corruption. If the file system refuses to mount and renders data inaccessible, do not run any utilities on it as it would aggravate the data loss and render data irretrievable even by expert data recovery professionals.

Replacing a failed drive with a drive that was part of a previous RAID system is an absolute no no.

Data Loss- Reasons and Costs

Home computer users and several computer experts believe that lost data gets permanently smashed, with no hope of retrieval. Information regarding lost data could be sophisticated, inaccurate or inconsistent, thus it is not unanticipated that the data loss and Hard Drive Recovery are some of the most misunderstood and confusing concepts of non-technical users.

The computer data might be one of the most precious and vulnerable assets of your company. Your mission critical and valuable data may get lost duet o any of the below given reasons:

• Hardware and system issues
• Operating system or system data structure corruption
• Virus infection
• Human errors
• Natural calamities

There five key threats to your data have two things in common: all of them are unpredictable and, in most of the cases, uncontrollable. Thus, you should always take precautions to prevent data loss.

With no access to your computer and no data, lost data could prove a financial disaster. The lost or inaccessible data might cost you in a large amount of money. The costs of data loss depends upon the type of your business. Following are some statistics, which shows the data loss costs per hour for some major type of businesses:

Industry Lost revenue per hour

Energy $2.8 Million
Telecommunication $2.0 Million
Manufacturing $1.6 Million
Financial Institutions $1.4 Million
Information Technology $1.3 Million

When the time is crucial and the lost data is business critical, Data Recovery might be the most realistic option you have. There are two major categories of recovery solutions- recovery software and recovery service.

The selection of appropriate recovery solution depends upon the cause of data loss. If you have lost your data due to logical damage such as file system corruption, virus infection, accidental deletion and more, Data Recovery software

can help you to easily recover data on your own. These applications are completely safe and easy to use. They use advanced scanning mechanisms to carry out effective and absolute recovery.

On the other hand, if your hard drive is experiencing electrical or mechanical issues, then you need to take assistance from Hard Drive Recovery professionals. They provide personalized and sophisticated recovery help, known as recovery service. It is performed in safe and sterile environment of Clean Rooms to ensure secure extraction of your valuable data.

How to Retrieve Data from a Dead Hard Drive

The computer hard drive isn’t proverbial for you, since you understand the calm nature of the hard drive. But, if the hard drive making strange clicking or scrapping noises, it is intimating you that this is about to fail and you should backup as much data as possible from it. Nothing could be more devastating than find your computer hard drive crashed and the backup is eventual resource to go through the Hard Drive Recovery.

When the usual mean of accessing data and information does not work due to some damage to the hard drive internals, the recovery service would help you to forcefully extract the missing, lost and inaccessible data. The recovery methods aren’t limited to only one way, but they depend upon the cause, type and extent of damage. The procedure is like resurrecting files and folders that have in fact lost their existence in confusing milieu of the hard drive.

Even if you are a technical user, the Data Recovery in such situations is never a relaxed process. Trying out the recovery on your own might cause more disasters and thus permanent data loss. The faults are quite obvious and include the stress of losing your critical and valuable data. Unless the needed expertise follows up drive recovery hands, the failed drive does not accept it for good.

The recovery companies have teams of qualified and experienced that could offer the pertinent handling and care that a failed drive requires. The recovery firms provide best help to recover your valuable documents, memorable pictures, tax statements, financial documents.

The hard drive recovery professionals can recover data even from a dead hard drive. They first completely analyze the drive to the type and extent of damage. After completion of Hard Drive Recovery evaluation process, they repair or replace the damaged components of hard drive and make the drive functional. Then they create the image of hard drive and perform recovery on the drive image and keep the original drive intact.

The recovery is carried out in safe and sterile environment of Clean Rooms to save the sensitive hard drive from further damaged due to dust particles. Data Recovery professionals use advanced tools and techniques to achieve absolute, safe and perfect recovery.

Data recovery is not Disaster recovery

Most of us are either unaware or oblivious about the gap that exists between data recovery and disaster recovery. Fraudulent usages and references regarding the two has merged their significance to such an extent that we barely differentiate them as separate entities embodying individual characteristics.

Data recovery refers to retrieval of data from inaccessible storage medias that have suffered reverses due to hardware or software malfunctions and data loss has followed as a natural corollary. Data recovery software is opted for when vital data, flagship bearer supporting the survival of your business is rendered inaccessible even after backup procedures have been employed. It is generally the last resort and often entrusted upon professionals specialized in data recovery.

Disaster recovery on the other hand deals with the implementation of a comprehensive data backup plan whereby the all-important data is backed up not in the computer but in a backup server or a local storage device wherefrom it can be retrieved if any data loss situation strikes.

Faults both mechanical and manmade that inflict crushing damages to the data are unnumbered but when natural disasters strike chances of data safeguard becomes bleak. In most cases, in spite of warnings from the meteorological departments, the impact and intensity of the natural disasters remains unanticipated rendering data safeguard difficult and impossible. It is during these times when disaster recovery serves its purpose.

One can reduce the incidence of data loss if one resorts to disaster recovery. Backing up the all-important data in an online server or an alternative server maximizes the chances of data retrieval following grave data loss situations. Mere backing up measures fall short when stolen Laptops and unscrupulous employees divulge company trade secrets. Redirecting vital data to an alternate physical location, i.e. another branch of the same company located in a different city or country can safeguard and protect the data from sabotage and can also prove to be productive in case a data loss situation strikes.

When mishaps of great magnitude strikes (lightning, flash floods, tornadoes), data recovery from rampaged hard drives recovery becomes mandatory. Malhandling the already damaged and corrupt storage media can wreak further damage rendering data retrieval completely impossible even by expert data recovery professionals.

Storage medias that have suffered onslaughts of natural calamities require services. Stellar Information Systems Ltd, a pioneer data recovery company specializing in Data recovery, security, safety solutions and services can help you in this regard. Stellar’s quality products, be it software or services have always delivered the best that the customer can get. Powerful algorithms backing the software execute the data recovery process while malfunctions in the storage media are set right through services. Whatever might be the extent of the damage caused, Stellar’s expert data recovery professionals are capable of retrieving data that have been subjected to any data loss situation.

Hard Disk Failure and Recovery Means

Hard disk is considered as a reliable storage device that can hold electronic data on magnetically coated platters. At start when Reynold Johnson invented it, the hard disk could store about five million characters. But as these hard disks are being pushed to the limits of technology, modern hard drives can now store up to 1 TB of data. As the hard disk’s storage capacity is increasing, so are the chances of hard disk crash and data loss. Since data plays a significant role in development of an individual or organization, in case when you lose data, you need to seek help from Data Recovery technicians.

Hard disk failure is the term used to denote the condition when hard disk breaks down to an extent that you cannot access the stored data. There is a wide variety of reasons that result into a failed hard drive, among which head crash is the most prominent one. In normal conditions, head floats at micrometers distance from the hard disk platters’ surfaces. Thus, any kind of collision results into data loss. Factors responsible for such behavior in a hard disk are:

• Exposure to sharp impact, high temperature and high magnetic waves
• Wear and tear
• Electronic malfunction
• Voltage fluctuations
• Power surges
• Physical shocks

The reason why we observe high failure rates is increasing spinning rate of hard disks while read/write operations. So, if anything goes erroneous while normal functioning of hard disk, it causes data loss at high rate.

Hard Disk Recovery experts follow variety of techniques to deal with such hard disks. The processes might involve steps like moving the disk platters to a healthy system, opening the hard disk to replace its internals and making disk images. Hard disk platters are extremely sensitive to the air borne particulates. So, for safe hard drive recovery, it necessitates opening a failed hard disk in dust-free and filtered surroundings, which only Clean Rooms can provide. Clean Rooms are special purposed surroundings used while highly complicated processes in chemical like industries. Their air-filtering power is determined by their class. For example, Class 100 Clean Rooms would mean that they the number of particles of size 0.5 µm or larger is permitted per cubic foot of air.
