RAID System Failure: What To Do When Your RAID Drive Fails - Technology

More and more small businesses are relying on the use of RAID technology for their storage needs. RAID systems provide users with increased storage capacity, greater reliability -- or both. But no computer technology is completely fail-proof. Power surges are one cause of RAID system failure. You should know what to do in the event of a power surge and failure in order to prevent catastrophic data loss.

But let's start with the basics: What is RAID?

What is RAID? RAID is an acronym for Redundant Array of Independent Disks and refers to the storage technology used, in this case, redundant combining of multiple disk drive components. RAID is commonly used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple physical drives.

The software to perform the RAID-functionality and control the hard disks can either be located on a separate controller card (a hardware RAID controller) or it can simply be a driver. Both Windows NT 4 and 2000 include a software RAID solution. Hardware RAID controllers cost more than pure software but they also offer better performance.

RAID systems can offer users an increase in storage capacity over traditional single hard disks. In addition, many RAID configurations offer data redundancy which provides protection of the data in the event of a system failure. But as is the case with other data storage mechanisms, RAID systems are susceptible to failure; if your business runs on a RAID server, you want to have an on-staff or outsource RAID data recovery service provider available in the event of an emergency.

Why RAID Systems FailA RAID system can fail for a variety of reasons. One of the top reasons RAID systems fail is power surges. These can be caused by storms, overheating, or simply voltage fluctuations if you plug your RAID server into an outlet without a surge protector.

A power surge can destroy the external electronic circuitry of any hard drive and cause irreversible damage to the delicate components inside the drive. What is known as a "head crash" occurs when the read/write arm inside the hard drive crashes down on the magnetic platters that house data and damage the platter surface.

If either of these things have taken place, you will most likely experience signs of failure, including:

- clicking sounds

- loss of power to the drive

- A message stating the drive is not recognized by the Operating System (OS)

It is possible to rebuild data after a RAID failure, but expert assistance is highly recommended. Data might be corrupt, petitions could be missing, or deleted files may be difficult for anyone but a

RAID data recovery expert to access.

RAID Drive Failure: Steps to Full Data Recovery

So, what should you do if you experience RAID failure? Number one: stop using the system in order to avoid permanent, catastrophic data loss.

Turn off your RIAD server to ensure no data may be written over any data you want to attempt to recover. Be sure to document the series of events that took place leading up to the RAID failure and make a note of anything you did to try to prevent it. Keep discs labeled in the order that they are removed from your system.

Regardless of the cause for RAID failure, it is critical to call a trained RAID recovery technician to recover your RAID drive to avoid permanent data corruption. If you takematters into your own hands, you could overwrite parity data, making RAID recovery more difficult.

Computer Forensics Certification Programs: What You Need To Know - Education - Online Education

Reports of major institutions, such as government bodies and large corporations, being attacked by online criminals are prevalent nowadays. Hackers and online thieves are armed with the sophisticated equipment as well as superb knowledge on penetrating the defenses of computer systems. A computer certification program levels the playing field as it imparts knowledge to aspirants on how to defend against hackers and follow digital trails leading to the identities of the perpetrators.

What is Computer Forensics?

Computer forensics, like with the forensic department of the police, covers the thorough examination of data in relation to online crimes and recovering data from corrupted computer systems. This IT field is diverse, touching on various disciplines, which include following a chain of custody ("digital paper trails"), different ways to back up files and examining various types of data.

Computer forensics experts are employed not just by the police, but also organizations that maintain computer systems. This means a specialist can get work from almost any industry, and the best part is, knowledge in computer forensics is an integral component of industry leaders.

Data Recovery-Locate, recover and restore - Computers - Software

Fail to save files, accidentally delete files, virus attacks your computer or computer system crashes, all these situations may cause the loss of data even we have fire wall, anti-virus software and a wide range of data backup software to protect files. Whichever you suffered, the losses are unbearable to you. But data recovery can take all the regret and upset away.

What is data recovery?Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally.

Often the data are being salvaged from storage media such as hard disk drives, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.

The most common "data recovery" scenario involves an operating system (OS) failure (typically on a single-disk, single-partition, single-OS system), in which case the goal is simply to copy all wanted files to another disk. This can be easily accomplished with a Live CD, most of which provide a means to mount the system drive and backup disks or removable media, and to move the files from the system disk to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.

Another scenario involves a disk-level failure, such as a compromised file system or disk partition or a hard disk failure. In any of these cases, the data cannot be easily read. Depending on the situation, solutions involve repairing the file system, partition table or master boot record, or hard disk recovery techniques ranging from software-based recovery of corrupted data to hardware replacement on a physically damaged disk. If hard disk recovery is necessary, the disk itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.

In a third scenario, files have been "deleted" from a storage medium. Typically, deleted files are not erased immediately; instead, references to them in the directory structure are removed, and the space they occupy is made available for later overwriting. In the meantime, the original file may be restored.

Although there is some confusion with the term, the term "data recovery" may be used to refer to such cases in the context of forensic purposes or spying.

What data recovery can do?Data recovery software can do everything of recover, recover data deleted from the recycle bin, recover data lost from damaged files, recover data lost due to virus attacks, recover data lost due to power outages, recover data lost from partially deleted hard drives, recover data lost from disks with bad sectors, recover different kinds of data like compressed and encrypted data, email, network file, and create image files and find lost data by name, date created or extension.
