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.
