Undoubtedly, Servers are the back-bone of organizations. A server can be a database server, application server or email server and stores all the precious data of the organization. That is the reason, if the server goes down even for a minute time, organization encounter huge financial or business loss.

Whether a normal server or a server with multi array RAID, NAS or SAN server, their data storage architectures are always complex. With huge volumes of important data in them, the servers become inaccessible at times. Though, organizations take measures to safe-guard their servers and the data in them, still some instance of data loss do happen.

There are a number of reasons behind the failure of a server, among which some of the prominent ones can be listed as below:

• Failure of the RAID Controller
• Rebuilding failure due to damaged drives or other reasons
• Corruption to the registry configuration of the server
• Intermittent drive failure, resulting in Server configuration corruption
• Failure of multiple hard drives simultaneously
• Reconfiguration of the RAID drives by mistake
• Corruption to the files system of system files of the server system
• Deletion of necessary files or data, while taking back-up.
• Severe physical damage to the server media due to natural disasters like fire, flood, storm and earthquake

In any of these instances of server failure, either your valuable data in the server drives gets lost or become completely inaccessible. In normal cases of logical data loss, where the data is inside a single hard drive, you can take the help of any data recovery software to recover the data back. But, in case of servers, there is RAID in them and data has been stored across multiple disk drives, in an unknown pattern.

Server recovery process is a systematic operation, which requires skills, expertise and high end infrastructure. In fact, the physically damaged drives of a server must be treated inside specially maintained lab environment of CLASS 100 Clean Rooms. Therefore, this is strictly the job of experts and for safe recovery of your valuable data, you must opt the services of any professional server data recovery service provider.

Stellar Data Recovery has been a leading provider of server data recovery services to many big organizations in India. With skilled professionals, advanced tools, techniques and state of the art infrastructure, such as CLASS 100 Clean Room labs, Stellar ensures maximum possible data recovery from the damaged server, within minimum turnaround time.

Soon after large organizations and industries started opting for computers, replacing paper files for their day to day operations, there arose a strong need for a large capacity storage media. As organizations deal with huge volumes of data, single hard drive based systems could not fill in the need. Moreover, with normal hard drives there was always a fear of hard drive failure and loss of data. All these facts led to the invention of RAID.

RAID is a wonderful technology that solved both the problems of data storage and data safety by facilitating storage of huge volumes of data alongside the fault tolerant mechanism. RAID is a technique, with which you can take together multiple hard drives together and build a single system. In RAID, though the hard drives have separate physically memory, but they work as a single logical memory. It has a unique data distribution technique and data is usually distributed across the connected disk drives. All these data storage and access processes are managed by a controller chip, called as RAID Controller.

There are different categories of RAID levels available, depending upon the number of disks and the fault tolerant mechanisms. RAID 0, RAID 1, RAID 5 etc are known to be the simple RAID levels, whereas RAID 6, RAID 6EE etc are termed as the complex ones. Some users even use multiple RAID levels, such as RAID 50 (RAID 5 + RAID 0), RAID 51 (RAID 5 + RAID 1) etc, making the RAID architecture more complex.

In case of RAID level 5 or above, if one disk fails, you can easily replace the troubled disk by a new one and start rebuilding. But, if two or disks fail simultaneously, you are in serious trouble, as a small wrong step can cause permanent loss of data. There are number reasons behind possible RAID failure, some of which are listed below:

• RAID controller failure
• RAID Array Failure
• Rebuild Failure
• Server Not Booting
• Hardware Failure
• Damaged Strip
• RAID configuration has been corrupt or overwritten
• Volume/ Partition not found etc.

Many users do not have enough knowledge about the RAID architecture and with experimentation; the RAID failure problem becomes more complex. Moreover, the data recovery from RAID needs huge expertise and advanced infrastructure, which are not affordable on the parts of individual organizations. Hence, for safe recovery of your valuable data, it is advised to take the assistance of any professional RAID data recovery service provider.

Stellar Data Recovery is a reliable RAID recovery service provider in India. With skilled engineers, advanced tools, techniques and state of the art infrastructure, like CLASS 100 Clean Room labs, Stellar ensures successful recovery of precious data back from any instance of RAID failure.

When industries first started using computers, the need was only to store data in a digital media instead of paper files. As the data was stored only on single hard drives, the data storage capacity was limited. Moreover, there was always a fear for hard drive failure and loss of precious data. These problems pave the way for inventing the technology, RAID. RAID solved the problems by providing huge data storage space and fault tolerant mechanism against any instance of physical hard drive failure. However, there are worse conditions, when even the advanced RAID array fails and you lose the access to valuable data stored in the connected drives. Under such situations, you can take the help of RAID recovery services and recover the lost/inaccessible data back.

RAID stands for the term – ‘Redundant Array of Independent Disks’. It is a useful technology that brings together multiple hard drives and builds a single fault tolerant system with huge storage capacity. RAID has been categorized into different levels, depending upon the fault tolerant mechanism and number of hard disks involved in it. In this respect, RAID 0, RAID 1, RAID 5 etc are considered as simple RAID levels, where as RAID 50, RAID 51, RAID 6, RAID 6EE, RAID ADG etc are considered as the complex ones.

RAID stores data by distributing them across multiple hard drives in a unique pattern. Data storage and retrieval process of the entire RAID array are managed by a controller chip – ‘RAID Controller’. In case of systems with RAID level 5 or above, if one of the disk drives fails, you can easily restore the data by the ‘Rebuild’ operation, after replacing the faulty drive. But, when two or more drives fail simultaneously, the situation becomes critical and even a small problem can cause serious loss or inaccessibility of precious data.

Due to their complex data storage architecture and data distribution pattern, data recovery from damaged RAID drives requires high level expertise and advanced tools. Therefore, it is always advised to take the help of any professional RAID data recovery service provider to do the job rather risking the data by self recovery attempts.

In this modern era, laptops have become essential part of the world. And, in this competitive world, it has become next to impossible to cope up your profession or your studies without the laptop. The factor which makes laptop popular among professionals as well as students is its portability and ease of carrying. But, every coin has two sides and so is the laptops, a laptop is highly prone to physical damages which results in data loss. To recover data in such scenarios, you need to have backup. However, if the backup is unavailable or corrupt then opting for reliable laptop hard drive recovery service is recommended.

Losing sensitive work related data or personal information from the laptop is always painful. Imagine the situation of a professional who ends up losing his vital information related to his latest project, last project’s data, and many more after accidentally dropping his laptop. This situation is hard to understand and especially considering that it could bring adverse effects on the carrier path of the professional. However, the good news is data recovery professionals are there to bring such professionals out from devastating situations (such as physical damage to hard drive and its various components) of data loss. Data recovery services can be acquired in various circumstances of data loss, some of which are listed below:

• Damage in laptop and its various components due to accidental dropping.

• Laptop hard drive inaccessibility or damage in the hard drive of laptop and its different components due to natural disasters like flood, fire, earthquake, storms, etc.

• Failure in the components of hard drive due to sudden power outage or power fluctuation.

• Hard disk data is inaccessible due to logical failures like file system corruption, virus infection, lost or deleted partitions, etc.

However, with all the above mentioned scenarios there can be various other situations in which one loses accessibility to his/her hard drive. But, reliable third-party hard drive recovery service provider can do the needful despite of the reason of data loss. One of the trusted names in the field of hard disk data recovery service is Stellar Information Systems Ltd. The organization has team of skilled data recovery technicians who ensure data recovery from different operating systems.

Hard Disk data loss is the problem which almost all computer users face at least once in a lifetime of their computer usage. But, with the advancement of information technology, no problem related to computers is unresolved today and so do hard disk data loss. Thus, through third-party hard disk recovery tools we now can recover data which is lost, deleted, or formatting due to various logical issues. However, the question arises here that how can we recover data if our hard disk is physically damaged. Well, for physically damaged hard disks we have various hard drive data recovery service providers which repair or replace the problem parts of the hard disk to make it working so that the entire data which is saved on this problem disk can be imaged on a different storage media and then carry out the task of hard disk data recovery.

Thus, the hard drive data recovery experts use this created image to reconstruct the data to another drive and try to fix all the damages which are caused to data. To carry out all these tasks carefully and successfully, high-ended technologies and tools are being used by data recovery experts. In this process one of the basic requirements is Class 100 Clean Rooms. The Clean Room has sterilized dust free environment, so that no dust particle can settle down between the read-write head and platters of hard disk. Therefore, irrespective of the brand of hard drive (Toshiba, Hitachi, Samsung, IBM, Maxtor, etc), the interface (Parallel ATA, SATA, SCSI, IDE, etc) it has, and the operating system (Windows, Mac, Novell, Linux, UNIX) it uses, an experienced hard drive data recovery service provider provides unbeatable service. Thus, the gist is we can get back all our data despite of the storage media we are using.

One of the highly dependable hard disk data recovery services providers is Stellar Information Systems Ltd. Stellar is ISO 9001:2008 certified organization which is in the field of data recovery services and software for more than 18 years and has more than 1, 100, 000 satisfied customers across the globe. This organization also has data recovery labs with Class 100 Clean Rooms where data recovery is being performed safely and carefully. Moreover, with its 24X5 customer service, the organization is trying to solve almost all the queries related to data loss and its recovery of customers. Since, Stellar follows No Recovery, No Charge policy and you have to make payment only after you data retrieval then if you are the one who is also suffering from the data loss due to any kind of physical damage of your hard disk then you can go for data recovery services provided by Stellar.

Have you ever encountered a situation in which you lost all the data saved on your computer due to fire in your office building? Although, in such case the insurance can cover all the financial losses but what happens to the data saved on your computer. The important information saved on your computer can lead to sudden downfall in your business. But, the good news is the data in such situation or all such similar situations is very much recoverable through reliable data recovery services. Well, I am saying all this because I suffered the same situation but thanks to Stellar Information Systems Ltd for recovering my vital data.

Let me narrate the whole incident in detail. Another day we got to know that our office caught fire and all the computers of our floor got burnt. To see the mishap site, I rushed to my office and horrified to see the situation. All the plastic components and electrical parts of computers were either melted or burnt. While the rest of the parts were struggling with the fire fighting tools such as sand and water. The loss was really unbearable as I could see that almost everything was burnt. However, I went to my computer and saw that the platters of the hard disk of my computer were not damaged. Worried, I started thinking about the files of which I had the backup.

However, at the same time one of my colleagues met and we started discussing about the mishap and at the same time I started regretting over the loss. He clamed me down and said that company was going to avail data recovery service provided by some third-party named Stellar. So we need not to worry about data as they would try to recover the maximum. Returning back I searched about Stellar Information Systems Ltd and found that it is one of the highly recommended data recovery service providers and is in the field of data recovery for past 18 years. Moreover, Stellar has its 13 data recovery labs across India and assures you up to 100% successful data recovery rate despite of instance of data loss.

Thus, after few days when office reopened almost all of us got all our data back. In the end I would just like to say that though you would find a number of computer data recovery service providers online if you search but it is recommended to go for the one which is in the field of data recovery services for a long time. And in this regards I must say Stellar Information Systems Ltd is the one which is ISO 9001:2008 certifies and follows “No Data No Charge” policy.

Laptop is basically a mobile computer which integrates all the necessary components which are required for proper functioning of a computer. Thus, it is designed in a way that we can keep it on our lap while working. However, at times its mobility makes it the prey of physical damage. In this situation the owner of the damaged laptop not only loses his laptop but also loses the precious data stored on its hard disk. But, thanks to third-party data recovery services providers for providing excellent hard disk repair and data recovery services. I too got to know about this fact after physically damaging my laptop but my timely decision that is to go for data recovery services provided by Stellar Information Systems Ltd recovered all my data.

Let me narrate the whole incident in detail after getting my first laptop soon after completing my high school, I felt as if I have got something for which I was waiting for a long time. Thus, with my laptop I used to do my assignments sitting on my bed, play video games while sitting in front of the TV with family, etc. I mean laptop bought mobility in my daily computer working. Another day to do my assignment in home, I took my laptop on my bed and sat in front of it on the chair. While doing the assignment, I put the headphones in my ear to listen songs. After half and hour or so, I realized that I needed my textbook to refer something. Unconsciously, I just stood up and moved, alas listened loud noise of something and understood laptop fell from the bed. The reason for falling was my own mistake as I stood up and moved without removing my headphones from my ear.

The situation was very critical as I laptop became unable to even start and I realized that some physical damage occurred in it. Worried, called my computer science teacher and told him the situation. He suggested me to instantly contact Stellar Information System Ltd for hard disk repair, for that he gave me Stellar’s phone number. I contacted them and took appointment to submit my laptop. On another day as per the schedule, reached Stellar’s office, submitted my laptop. Since, exposing the hard disk in a normal room environment is strictly prohibited but people generally do that which leads to beyond recovery data loss. So they appreciated my quick decision of taking the laptop to them and not trying to expose the laptop y my own. Thus, in few days I got back my laptop with all the data intact.

In the end I would just like to say thanks to Stellar Information Systems for their quick customer care response and incompatible high-quality data recovery service. The experienced data recovery engineers of Stellar expose the affected hard disk in dust free class 100 Clean Room Environment by using cutting-edge technology. Thus, provide maximum data recovery.

Many of us even today are unaware of computer data recovery. It is basically method of pulling out the data from inaccessible or accessible hard disk or other electronic storage media. Thus, to recover our data we always have two options namely data recovery software and data recovery services. Data recovery software can recover the data in the cases where the hard drive or other storage media is accessible. But, in the cases where the storage media itself has become inaccessible then data recovery services are the only way of resolving the issue and getting the data back. I too learn about this fact sometimes back and after researching over this topic, I came across some very interesting facts about data recovery which I would like to share with all of you.

Most commonly the data loss can be of four types:

• The file or folder in which the data is stored has become corrupt or damaged.

• The file or folder has been deleted completely (without any trace in the recycle bin), or is lost.

• The storage media has become non-responsive or inaccessible.

• The storage media is lost.

The first two situations of data loss call for powerful and efficient data recovery software where as the third situation calls for expert data recovery services. In the fourth situation, only the police can assist you best. However, in this blog we will discuss more about data recovery services. With the rapid increase in the electronic storage media, the cases of data loss have also increased. Thus, keeping this in mind various companies are providing data recovery service today but the question is how a person would understand about the right data recovery service and reliable data recovery service provider.

Since, not all the service providers have special rooms with controlled environment to open a storage media thus, it is recommended to opt for the one which has Class 100 Clean Room (a perfect environment to expose storage device). However, if a service provider claims to have this environment then it is advisable to go for the one which has ample experience in the field of data recovery. Also make sure that they support the file system of your storage media, its interface, etc.

When industries first started computerizing their records, data servers were like a collection of multiple storage drives, simply connected to a system with high processing speed. In those systems, if a single hard drive failed, the organization had to lose all the data, stored in that drive. Then, industries started keeping multiple copies of data in drives so that if one drive failed, there would be always a second drive as backup. But, this fashion of data storage increased the storage cost. Moreover, when one drive can fail, there is enough chance that the second backup drive may also fail at time. All these problems initiated the invention of a fault tolerant system, RAID server.

RAID stands for ‘Redundant Array of inexpensive Disks’. RAID is a technology to configure a single fault tolerant system by taking together multiple numbers of individual hard disk drives. The entire set of hard drives appears as a single logical drive and is managed through a controller, called RAID Controller. Apart from huge storage capacity, the main advantage of using RAID is its fault tolerant nature. RAID has such a storage architecture that if one disk fails and becomes completely inaccessible; still the data can be easily recovered from the other disks.

There are different types of RAID available, depending upon the number of hard drives as well as their fault tolerant mechanisms – RAID 0, RAID 1, RAID 5, RAID 50, RAID 6, RAID 6EE etc. In case of RAID 5 and above, if one hard disk fails, you can easily restore the data back. But, if there is a simultaneous failure of multiple hard drives, it can be problematic and a small mistake can make you lose all the data in the RAID array.

Apart from normal mechanical/electrical/firmware failure of hard drives, below are some of the prominent reasons behind RAID failure:
RAID controller failure
Damage to the RAID array configuration
Modification of the RAID configuration
RAID rebuild failure
Natural disasters (Fire, Earthquake, Flood etc.)

However, in any of the above situations of RAID failure, all the data from the inaccessible drives can be recovered by RAID recovery services. But, in this regard, the important thing is that RAID recovery is a strictly systematic process and needs experience, expertise and advanced infrastructure. Hence, for the safe recovery of the data from the troubled RAID drives, it is always advisable not to experiment with the system, post failure and immediately opt for the assistance of any good RAID data recovery service provider.

RAID is a technology that helps in configuring a fault tolerant system by taking together multiple numbers of hard drives. RAID or ‘Redundant Array of Independent Disks’ is an innovative technology to increase storage space and improve data safety. However, in spite of its fault tolerant mechanisms, there are situations, when the RAID system fails and the data becomes completely inaccessible. RAID has complex data storage architecture and thus while trying to recover data from the damaged RAID drives, if you make any mistake, then you may lose all your data. Hence, it is always advised to take the help of any professional RAID recovery service provider for safe recovery of your precious data.

These days, with the growing need of storing huge amount of data and avoid losing data to hard drive failures; many organizations are using RAID in their servers. RAID has improved the storage capacity of various servers to a large extent. Moreover, due to the fault tolerant mechanisms involved in RAID, users feel secure against data loss or inaccessibility.

RAID is available in different categories, depending upon the number of disks in the corresponding RAID array and the fault tolerant mechanisms. Some RAID levels, such as RAID 1, RAID 0, RAID 5 are considered as simple, whereas RAID 50, RAID 51, RAID 6, RAID 6EE are known to be the most complex ones. Some RAID arrays, like RAID 51, RAID 50 are implemented by taking together two different RAID levels. Every RAID level has an unique data distribution pattern and the entire process of data management is controlled by the RAID Controller.

In case of RAID level 5 or above, failure of a single disk can be handled by replacing with a new disk and rebuilding the data back. But, if more than one disk fail simultaneously, the problem becomes critical and you need to opt for RAID recovery services.

Now-a-days, there are many RAID data recovery service providers available in the market. But, as the job involves recovery of your precious data, you need to be extra careful in choosing the service provider. In India, Stellar Data Recovery has been the most reliable name in the field of data recovery services. Stellar with its in-house R & D, innovative tools, techniques and skilled data recovery professionals, ensure successful recovery of valuable data from the troubles RAID drives.
