Data loss can be very detrimental to any individual user or company especially in East Africa whereby companies are growing at a very promising rate. Companies tend to save all their data in raidserverswhich are no exception to failure. In event of failure of these servers whereby there are no backups of the data, these companies tend to lose a lot of business and it might lead to the uneventful death of the companies.

Even for individuals, data loss also causes a lot of agony to these individuals. If you ever find yourself in such a situation where your hard drive crashes, falls, starts making some clicking noises inside(a sign that your hard drive might crash at any time) or any other case whereby your data is inaccessible, avoid using the freely available data recovery software especially if you are no data recovery expert as they tend to cause more harm than good to your data and hard drive or any other storage media that you may be trying to recover the data from thus making it difficult to perform any data recovery on it.

Some of the storage devices that are recoverable include; Data Recovery on Hard Disks, Servers,Laptops, Mobile Phones, NAS, SAN, RAID, Memory Cards, SSD Drives,Flash Drives etc.

You may also try and disconnect the server from power to ensure or minimize the physical damage to the hard drives and for the removable media, disconnect it from the computer and contact data recovery experts who may help in RAID data recovery in servers and also hard drive or nay digital storage media data recovery.

RAID stands for Redundant Array OF Independent Discs, which is a data storage technology that combines multiple physical disk drives into a single logical unit for the purpose of data redundancy or even both.
1) Software RAID: RAID system that doesn’t require a dedicated hardware RAID controller. The RAID compatibility depends on the operating system. It applies whereby there is a single disk with two partitions; one to boot from and the other for data storage.
2) Hardware/Physical RAID: RAID controllers are required in this setup. This controllers support different levels of RAID and also specify the kinds of disks to be used in the array; SSD, SATA OR SAS.
RAID 0: Consists of stripping, without mirroring of parity. The capacity of this level of RAID is the sum of all the disks in the set. Failure of one disk in the set causes loss of the entire RAID and the chances of data recovery are minimized.
RAID 1: Consists of data mirroring, without parity or stripping. Data is written identically to two or more drives therefore producing a mirrored set of drives in the set.
RAID 2: Consists of bit-level stripping whereby data is stripped in a way that each sequential bit is on a different drive.
RAID 3: Consists of byte-level stripping whereby data is stripped in a way that each sequential byte is on a different drive.
RAID 4: Consists of block-level stripping with dedicated parity whereby the read/write operations do not spread across all data drives.
RAID 5: Consists of block-level stripping with distributed parity whereby the parity info is distributed among all drives requiring all drives but one to be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.
RAID 6: Consists of block-level stripping with double distributed parity. This provides fault tolerance of up to two failed drives.
Nested (Hybrid) RAID: Many controllers allow RAID levels to be nested. The elements of RAID may be individual drives or arrays by themselves.

Note: Attempting to recover a RAID without an unexperienced data recovery specialist can put your critical data at further risk. When hardware malfunction is a component of the problem, permanent destruction of data can occur with failed recovery attempts.

With alot of experience on Raid recovery and through our advanced and up to date technology.East Africa Recovery Experts has the capacity and technical expertise required to solve complex, technically challenging RAID recoveries.


Why Data Recovery Is So Important?

Data Recovery typically refers to the Restoration of data to a desktop, laptop, server, or external Storage system from a backup. Because Data is the heart of the Enterprise, it’s crucial for you to protect it. And to protect your Organization’s Data, you need to implement a Data Recovery Plan. While it’s important to know the best tactics for data recovery, preventing the loss of data in the first place is vital. Backing up files can protect againstAccidental Loss of user Data, Database Corruption, Hardware Failures, and even Natural Disasters.  All in all Consumers need to engage in some best practices to ensure their data is protected.

The DataRecovery process may vary, depending on the circumstances of the Data Loss, the data recovery software used to create the backup, and the backup target media. Data recovery is provided as service. Such services are typically used to retrieve important files that were not backed up and accidentally deleted from a computer’s file system but still remain on disk in fragments.

We live in the digital age where technology is supreme. From the individual household to multinational conglomerates, we rely heavily on our computers and machines for business, even leisure and simple day to day information needs. Critical to this all is the data storage that allows for it all to happen. So it is understandable that the loss of this data can be problematic in some cases and catastrophic in others. It is a result of this dependency that data storage mediums have been developed, which inadvertently opens up the niche in the market for DataRecovery Services. These are services that are becoming more and more important as the world’s reliance on stored data increases.

As the name implies, Data Recovery Services refer to the business of Salvaging Data from Storage Media that have been Damaged, Corrupted, have Failed or areInaccessible for a host of other reasons. The storage media that these data recovery services relate to, deal with a range of storage devices from CD’s, DVD’s, flash drives, hard drives to various other devices.

Data storage is for the most part important on a personal level. Storage Media is used to keep photos, notes and other personal effects in Data form. Some information can be Very Sensitive such as scanned images of ID Documents, Financial Records and so on. As a result of this, a hard drive crash or similar situation that results in theLoss of Data could be considered a Tragic Loss of Sentimental and Confidential Data Items. For many this is more than a good enough reason to seek out the sought-after help ofData RecoveryExperts. Others might have Lost Data relating to their work or business. In this case the loss could cause Financial Problems, issues with the receiver of Revenue and Stress related to the Waste of Work hours connected to the data.

On a more far reaching note, there is the Data Loss associated with Government orIntelligence Services, which influences not only the Organization but entire Communities or even Nations. Such Loss can have grim Consequences Economically, Managerially, in terms of Governance, Socially and even Politically.In some cases where the information is of a restricted level, there might not be comprehensive backups due to secrecy issues.

Although, depending on the scale of the failure or damage to the storage medium,Data Recovery is not guaranteed, in most cases the recovery services are successful. In spite of not being a flawless solution recovery executed by Data Recovery Expertscan produce results in the range of between 80% to 100% depending on the specific case and surrounding circumstances of the Data Loss or Inaccessibility


If you’re reading this then you probably know that there are different types of RAID systems and if not the following link will assist you to comprehend it better: . With that issue out of the way,we will focus mainly on the RAID 5 system which is described as ‘fault resistant’, meaning that it can tolerate failure of a hard disk drive with the data on it still being available and readable. That being said the fault resistant part tolerates failure for only one hard drive and not more than that for RAID 5 whereas for RAID 6 the limit is increased to two drives. When it comes to RAID 5 there are three key points to note;
  1. The array must consist of three or more hard drive elements.
  2. The Reliable Availability of data stored can tolerate the failure of no more than one hard drive element.
  3. rebuild procedure will always fail unless all components (controller and all hard drive elements) are present.
In the case where you cannot access and/or backup all the data stored in your RAID 5, do not attempt to rebuild it, contact the data recovery experts immediately. However, if you can back it up, do it first and fast to avoid total data loss. Any failed rebuild attempts reduce the chances of successful data recovery.
  • Do not use RAID 5 as a backup solution; it is essentially a scheme to increase data availability.
  • Do not opt for rebuilding a RAID 5 as the first data recovery solution since you can ideally read all the data and ensure all the data contained on the subsystem is backed up before rebuilding.
  • Do not continue with any corrective actions once you realize that more than one of the hard drive elements is faulty. Seek professional assistance from the data recovery experts immediately.
  • Do not ever ignore any RAID 5 subsystem fault warning or any behavioral inconsistency. Once one drive fails, perform a backup immediately as you are running on a downgraded RAIDS whereby the fault tolerance is lost and if any other drive malfunctions your data may be lost.
  • Do not remove more than one drive simultaneously from its initially installed position as you may lose track of the sequencing of the drives. It is thus advisable to label the drives matching them with their slot while removing them.
  • Do not allow the controller to execute write operations on any known working drive as it will overwrite the stripping data needed for reconstruction.
  • Do not use CHKDSK or any other disk utility tools but if they should be used, be used with caution. The rate of success when using these tools is very low so, do not risk using them.
  • Do not shuffle the physical arrangement of the drives since the controller might not detect these changes.
  • Do not insist on trying out numerous ‘experiments’ in efforts to bring an inaccessible drive back online. These attempts might increase the damage to the RAID, reduce the chances of data recovery and maybe increase the cost of the data recovery itself. It is therefore recommended you reach out to the data recovery experts sooner rather than later.
  • Perform regular backups on the RAID just like any other data storage media to be safe since you never know when disaster may strike


Have you Lost Data? Your Next Steps are very Crucial!

To avoid permanent data loss, follow these simple steps:

  • If your hard drive is making clicking, grinding or whirring sounds, shut down the drive or your computer immediately. These sounds could be the read/write heads hitting or scraping the hard disk platters. Severe or complete data loss could result.
  • If your data is important, make sure you choose a reputable recovery firm that can properly recover data from mechanically failed or physically damaged drives. Even the simplest recovery attempts could render your data unrecoverable.
  • Avoid “home remedies” you may have read about on the web such as placing a non-spinning hard drive in a freezer or hitting a drive on its side. Much of this information is inaccurate and while some may claim success, these suggestions may actually harm the device and could lead to permanent data loss. We recommend that you do not gamble with your irreplaceable data.
  • The first recovery attempt is always the best recovery attempt. At East Africa Recovery Experts, our engineers use the safest methods available to ensure your data is not lost from repeated recovery attempts.

Preventing Data Loss

Everyone should adopt strategies to ensure critical information is protected from corruption and loss.

Best Practices:

  • Never upgrade to a new version of an operating system without having a verified backup
  • Use up-to-date hardware and software utilities for data security, such as firewalls and virus protection
  • Scan all incoming data; such as emails, websites and downloads for viruses and malware
  • Connect computers to an uninterruptible power supply (UPS) to protect against power surges
  • Avoid static discharge when touching or handling any storage media, especially in excessively dry environments
