RAID-configured systems offer a wide range of benefits such as safer storage and improved performance. However, despite these advantages, these systems can develop technical failures for to various reasons. When this happens, it is always advisable to look for professional RAID Data Recovery Services.

It is not easy to recover data from RAID systems. Any simple mistake during the recovery process is enough to create more damage to the remaining data, eventually losing everything that would have been recovered by a professional. This happens mostly when an individual does not have in-depth knowledge of the configuration of RAID arrays at the software, firmware and hardware levels.

There are four main reasons why RAID arrays fail: hardware, human error, software and application errors. Hardware failure is usually caused by bad sectors, fire damage, controller malfunction, disk overheat and other similar physical factors. Human error is caused by unintentional deletion of files, lost log-in details or overwritten RAID settings.

Software failures occur as a result of back up errors, computer viruses or directory corruption. Lastly, application failure can occur due to corrupted files, deleted tables or locked orinaccessable databases.

None of these problems are easy to fix especially if the individual is not an expert in complex RAID systems. Each problem comes with its own recovery procedures which need to be followed strictly. Since there is no standard recovery method for every problem, it makes this task harder than ever.

Companies that value their privacy and important data do not have to worry when their RAID systems fail as long as they hire a professional IT company that provides quality recovery services. Such a company is capable of backing up the data before launching their recovery processes which use advanced technology. Their techniques ensure that no more files are lost before or after recovery.

About RAID Data Recovery

A wide majority of small-to-medium business enterprises across the world have nowadays turned to RAID-configured systems, services for most if not all of their storage solutions. Some of the most frequently given reasons for opting to utilize RAID Arrays services in business enterprises today are the highly fault-tolerant levels that the solution offers its users and the most of all the cost effectiveness of the acquisition and maintenance of the system.

This is, however, accompanied by an anticlimax that, if for some reason a RAID Array fails as may be a result of component malfunctions (such as hard disk drives and controller cards) or even in the event of operating and application corruption, then it leaves all the data unusable and in most cases than not corrupted.

RAID data recovery is an extremely intricate task since the RAID data configurations most of the times have different forms of data layouts depending on their manufacturers, this is often for competitive purposes. Therefore, it goes without saying that without an in-depth and acute knowledge of how RAID arrays are usually configured in hardware, firmware and even software levels, the data recovery attempts will not only fail completely, but will also result in far much worse data corruption.

By putting into use its vast knowledge of RAID Array storage technology systems, some companies such as Seagate Recovery Services can reliably and successfully manage to recover data from the very earliest to the most recent SAN, NAS and Server RAID configurations available in the market today.

Guidelines for Raid Data Recovery

In the event that you have realized that you are handling a RAID failure and therefore you will need Raid Data recovery, the first step is to write down all that you know about the original configuration of the array i.e. ensure that you label all the member disks with a marker. These, along with the drive disks, also label the controller ports and all the cables. Then subsequently you can use the numbering format to refer to any particular disk. RAID recovery normally implies the recovery of logical RAID configuration that is made up of the following parameters; RAID type, number of its member disks and their order, block sizes, start, offset for data on member disks (this information is in most cases not given).

The logical RAID configuration is accessible in RAID controller BIOS or in RAID monitoring and configuration software. If you manage to determine all parameters, RAID recovery is accomplished for you. All the information relates to the preparation to RAID recovery that aims at reconstructing missing RAID configuration parameters. All of the information given above must be collected so as to enable you return to the original configuration should there be a need to.

A computer crash also known as a system crash, refers to the event whereby a computer program such as a software application or even an operating system stops functioning normally. It will in most cases than often exit the affected program soon after encountering this type of error. The program responsible for the crash may appear to freeze until a crash reporting service, that usually alerts the user about the crash, reports the crash and potentially all the details relating to it. Should it be that the program is a critical part of the operating system, and then the entire computer may end up crashing, which often results in a fatal system error, usually signified by the ominous blue screen. In most cases the crashes are as a result of a single or multiple machine instructions running incorrectly. In such cases it is paramount that the necessary Data Recovery Procedures be established.

Common Causes of Computer Crashes

In most case scenarios the crash occurs unexpectedly, leaving one dumbfounded on what may have transpired and what exactly to do about it. It is critical for each and every person working with computers or using them for data storage purposes be well acquainted with the data recovery procedures as this will come in handy in the sudden unwanted event of your computer crashing.

A computer crash may be caused by a number of factors, including; the use of an outdated or in some cases misbehaving device driver, a computer virus is also a common cause of computer crashes, the use of a corrupted program, or it may be that the problem is actually with your computer’s memory. The solutions to sort out these problems also vary widely as well, depending on the particular problem.

How to Go About the Data Recovery Procedure

The process of data recovery on the drive normally starts with one evaluating of the drive. Soon after the data recovery, hard drive company you have outsourced receive your failed hard drive, the media will then be logged into their system for the purpose of evaluation. This is usually performed by the data recovery technicians. They will give you their initial diagnosis, including total recovery costs as well as the estimated duration of the data recovery, hard drive procedure starting from the date of receiving your hard drive. Most data recovery, hard drive companies are actually able to repair the damaged drive within a period of 24 to 48 hours.

Then after the Data Recovery Drive evaluation process is complete, the company normally waits for the customer’s approval in order to proceed. Once they have received the approval to go ahead with the data recovery procedure, the damaged hard drive is then being “cloned”. It is then re-queued for real data recovery procedures. Some data recovery companies offer expedited services for their members after the evaluation procedure. For them, this service allows the customers’ drive to avoid the recovery queue and therefore become next in line for the data recovery.

Computer forensics, also referred to as Computer Forensic Science is actually a branch of digital forensic science that pertains to the legal evidence that is found in computers alongside other forms of digital storage media. The main goal of computer forensics is basically to examine the digital media in a forensically sound perspective with the main aim of identifying, securing, recovering, analyzing and presenting the facts and opinions about that particular digital information. And many colleges are now offering degrees in the field of computer forensics.

Even though it is in most cases associated with the investigation of a large variety of computer crime, computer forensics can also be used in certain civil proceedings. The discipline basically involves the use of similar techniques and principles of data recovery, but also with additional guidelines and practices that are designed to create a legal audit trail. The evidence from computer forensics investigations is usually put through the same guidelines and practices as other digital evidence

All about Computer Forensics

When we talk about computer forensics it basically relates to the use and application of special analytical methods employed to get, authenticate, preserve, recover, and analyze the electronic data meant for legal purposes. In other words, applied forensic computing is technically made up of four main stages, namely: Identification of the sources of the digital evidence required, securing and preserving the identified evidence, analyzing the evidence that has been acquired and finally documenting the legally admissible evidence to be presented.

According to the computer forensics world, the most likely of scenarios in which forensic computing is also employed include, accidental or deliberate unauthorized disclosure or access to corporate data, employee internet misuse or abuse, damage assessments and analysis, industrial espionage and or criminal fraud and the deception cases.


Careers in Computer Forensics

A Computer Forensics Investigator or just Forensic Analyst is a particularly trained professional working alongside law agencies, and private firms, so as to retrieve data from computers as well as other storage devices. The equipment can at times be damaged either internally or externally corrupted by way of viruses or hacking.

The Forensic Analyst is known for working just within the law enforcement industry; however, he or she may also be tasked to test the security of private companies’ information systems. The analyst must have an excellent working knowledge of all the aspects of the computer inclusive of but not limited to the hard drives, networking, and encryption. Patience and the endurance to work long hours are some of the qualities that are well-suited for undertaking this position.

During criminal investigations, the analyst recovers and examines the data from computers and other data storage devices in order to use the data as the evidence in criminal prosecutions. In case the equipment is damaged, the analyst must by all means dismantle and rebuild the system so as to recover the lost data. After retrieving the data, the analyst then writes up technical reports detailing on how the computer evidence was discovered and all steps taken in the retrieval process.

Data salvage or recovery refers to the process of retrieving and managing the information through the records from essentially either damaged or even corrupted and inaccessible the secondary storage your devices when it cannot be accessed through the normal way. Most of the time the data is being saved from Storage Media Devices such as the external or internal hard disks, solid-state drives, USB flash disks or memory sticks, storage tapes, Compact disks, Digital versatile disks, RAID, and other electronic storage devices. The recovery may be required due to the physical damage to the storage device or the logical damage to the device file system that thereby prevents it from being mounted by the host operating system.


Data Salvaging Tools

The main data salvaging tools basically are a wide range of data salvage software that is made available by the data salvaging companies. These can be accessed online for a fee or are in some cases offered for by the data salvaging companies and it is easy to download them and put them to use. There are also a couple of simple instructions that are made available to give directions to those users that may not be very well acquainted with the procedures of using the software. However, in cases where the damage to the data storage device is extreme, one may have to ship it to the data recovery company so that they employ the use of special machinery and procedures to be able to retrieve the data.

Data salvaging Process

One of the best data salvage techniques is to ensure that you have data already backed up on another storage device, be it on the same computer, or on a network server or even the Internet. Then the data recovery becomes a very simple copy procedure after the failed storage device has been replaced. In the worst case scenario, some if not all applications may have to be re-installed if only the user data was the one backed up, however, unless the applications are that of vintage programs may no longer available, the data is far much more valuable than the software itself.

In the scenario whereby there is no backup and the data has to be recovered, there are a number of organizations that normally specialize in the retrieval of data from the damaged computers. They may use different techniques as being able to move the drive to another working computer, or they may just have to open the drive itself and replace certain parts such as the read/write heads, the actuator arms and the chips. In certain cases, the platters are removed and then placed into another drive.

The newer disk drives are usually tested during manufacture, and parameters that are unique to that drive stored in its firmware. As one uses the drive, data regarding bad sectors are also added. In case the drive is badly damaged in the areas which contain the drive information, replacing the parts may not be enough for recovery of the data.

This is basically a controller card disk which is capable of supporting one or more configurations. It was originally meant only for the SCSI drives, but the RAID Controllers just became really popular for both the SATA and PATA drives

What are RAID Controllers

It is technically a device that manages the physical disk drives, and then thereby presents them to the computer in such a form as of logical units. Yet in most cases, implements hardware, thus it is sometimes referred to as RAID controller. It also often useful in that it provides the additional disk cache. The  controller is capable of offering a level of notion between the operating system as well as the physical computer drives. The RAID controller provides groups of the various applications and the operating systems, as logical units for which the data protection schemes can then be defined. Since the controller is capable of accessing multiple copies of various data on multiple devices, it is therefore capable of improving performance and can protect data in the event that a system crash occurs.

In the Hardware-Based RAID, physical controllers is used in managing the RAID arrangement. The controller can also take various forms such as a PCI or PCI Express card that is designed to support only a specific drive format like SATA. However, some of the RAID controllers could also be integrated with motherboards. The controller may also be software-purely, thereby using the hardware resources belonging to the host system. The Software-based RAID generally gives similar functionality as to that which is hardware-based RAID, but typically less in performance than of the hardware versions.

RAID Controller Failure Causes and Remedies

RAID controller failures may occur due to a variety of reasons. Normally a technician would assume that one of the drives has failed.  It is a very common diagnosis for RAID controller failures as the diagnostic lights on the drives may be blinking, gone orange, or as may be in some cases the drive may not be spinning.  These surface indicators would definitely lead the technician to assume that the drives have either failed or are on their way out.  There is, however, another reason why all these things might occur, and that would definitely be a RAID controller failure.  The challenge is to be able to diagnose the problem with a damaged controller.

However, despite the advantages offered by the RAID arrays, there are certain disadvantages as well, e.g. should the RAID controller fail, it will become very hard or even in some cases not possible to continue making use of the RAID array in the original arrangement. In various cases, the user data and files end up becoming inaccessible with no original or a well-suited RAID controller required.

In the event that your RAID controller does fail and you need access to your data, you need to consider making use of a dedicated RAID recovery device to be able to recover data and files from the inaccessible array and putting all the recovered files onto one hard disk.

Seagate Momentus XT 500GB  is the fastest hard drive

Seagate introduced a technology that finally bridges the gap between the fast SSD and the huge space of HDD. This is ideal for those notebook users’ enthusiasts who don’t have an extra drive bay for additional drive.

There are two options to attain the speed limit that you want, first get a super fast and expensive SSD but suffer from low disk space. Second, get a high rotational speed mechanical hard drive but suffers from being noisy, overheat and draw much power. This often leads to hard drive failure and hard drive recovery needs.

Seagate solve these problems by creating a hybrid drive by getting the speed of the SSD at the same time having a huge storage. This is good news to anyone who doesn’t like the idea of having two hard drives at the same time. With buying both SSD as your boot drive and mechanical drive as your storage will cost you too much penny.

The Momentus XT is a 2.5 inch drive that uses both the Nand memory from SSD and a mechanical drive. The mechanical drive spins the disk at regular speed of 7200rpm with a capacity of 500GB in a 3GB/s SATA interface. This perfectly fits all notebooks and can also be used for desktop PC.

What Makes It Fast

The Seagate Momentus uses a 4GB SSD that serves as a huge cache memory aside from its 32MB buffer. The 4GB SSD memory are used to store your most frequently accessed programs such as games, Adobe Photoshop and MS office. This also includes the operating system you’re using.

Seagate called this special algorithm technique as the Adaptive Memory Technology. With this kind of technology, this makes it a lot faster to load those programs because it is merely stored on the SSD memory without the needs to pull out from the hard drive disk. As a result, it gains up to 40 to 50 percent in speed, windows loading time will boost twice faster than regular mechanical drive.

The only problem arises here is that, if the user is frequently changes his data access. The 4GB memory acts only as a read only, you can never write on it. In short, there’s no way you can choose what you like to put in it. The drive does only analyze your access pattern and writes it on the SSD for the most frequently used data.

Seagate Momentus XT In Action

In PC mark vantage test, we can expect a performance in between the real SSD and HDD. This means that, the SSD still on leads speed but close enough and by far shows vast improvements compare with the HDD.

Everybody wants a fast windows boot up, admittedly we don’t have the patience to wait for long a time to load the OS so that we can start using it immediately. We can notice it clearly in the windows startup test a tremendous gains of 40 percent. It means that, a typical 60 seconds booting time will take you only 36 minutes.

In a sequential read/write operation, the 4GB NAND memory seems to be useless in this case. This fairly operates only as a regular 7200rpm hard drive. Even though without the NAND memory, the Momentus XT still shows a faster speed compare with other conventional 2.5 inch drive.


The Seagate Momentus XT shows a solid performance and very dependable drive. The hybrid technology it offers results in a vast improvement in speed but, some of its minor disadvantages are also clearly seen. Seagate’s main purpose is to create the fastest drive with large capacity, and I should say that they become successful in this area by beating all traditional hard drive with 500GB of storage capacity.

The inclusion of 4GB SLC NAND memory on the drive is a brilliant idea, although it’s only a small amount this alone makes a huge difference in speed. Compare with the high-speed rpm VelociRaptor, the Momentus has taken all the advantage with low power, quieter and cooler.

This drives are for those who wants speed and large disk space combined in a single drive as well as for notebook users. The boot up process and running your daily program applications are absolutely fast, this makes everybody happy.

Computer parts are currently being sold in almost any online store. With this in mind, you will have to be careful when you are planning on purchasing the same. For starters, you will need to know the source you are buying your parts from before you make a decision. In the present day, unscrupulous dealers have penetrated several online stores including those that have a good reputation good example of such a store is eBay. Despite it being one of the most trustworthy suppliers, there are scammers and conmen who have infiltrated the same.


How to be careful when buying from eBay

If you wish to purchase computer parts from a reputed online store such as eBay, there are some factors you should take into consideration. As a high ranking store, eBay has put into place some protocols that will assist any prospective buyer when they want to purchase anything from their store.


One of these protocols is the seller review / rating you can view on each seller’s profile. The ratings / reviews are done according to the satisfaction that the buyer received when they were sold goods by the said seller. For this protocol to work, every buyer has to leave a review, whether positive or negative, regarding the experience they had with a particular seller. They have to rate things such as the cost of the goods, the service delivery and the authenticity of the goods they received.


For example, if a seller was selling a computer memory card and sated that it was 1GB, an interested buyer will pay for the same. Once they have paid, the seller will be required to ship the good(s) to him / her within a stipulated time frame. Once the buyer has received what they paid for, they will need to go back to the site and rate the seller using a number of criteria. Basically, they will rate the seller according to the condition(s) of the product, its efficiency and the time it took for the product to be delivered.


This system is effective as it will allow the buyer recommend or discourage the buyer to other sellers. The system is effective as it will help any future buyers to know if the seller they want to buy from is actually trustworthy or not. For instance, if you buy a computer part that was faulty or was not what you had initially ordered, you can use the review and rating platform to state the same. A future buyer interested in buying the same from the said seller will refrain from doing so because of the information and poor review you gave the buyer who sold you what you did not want.


The last reason why you should be careful when buying computer parts from eBay is the fact that there has been an influx of generic products (imitations) from the said site. Even legitimate sellers are opting to buy generic parts and selling them because they are cheaper than their original counterparts. If you are not careful, you may end up purchasing a memory stick that has a similar name to that which you use, but it is actually from a different company. Always be on the lookout and take into consideration the reviews of sellers before purchasing any computer part on eBay.
