RAID DATA RECOVERY KENYA

August 19, 2016 No Comments Data Recovery

RAID SYSTEMS
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.
  TYPES OF RAID SYSTEMS
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.
LEVELS OF RAID
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.

DATA RECOVERY TIPS

November 8, 2015 No Comments Data Recovery

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

Data Recovery: What to do when hard drive fails

October 26, 2015 No Comments Data Recovery

Having a hard drive fail can be a frustrating and stressful experience. But don’t worry, there are some things you can do to minimize the damage and get your data back. In this blog post, we’ll give you a few tips on what to do when your hard drive fails.

  1. if your hard drive is making any strange noises, it’s important to turn it off immediately. If you can, unplug it from your computer and remove any external cables. This will help prevent further damage to the hard drive.
  2. Next, try to connect the hard drive to another computer. This will help you determine if the problem is with the hard drive or the computer itself. If the hard drive works on the other computer, you may be able to recover your data. But if the hard drive doesn’t work on the other computer, the data is probably lost.
  3. If you can’t access your hard drive at all, you can try using data recovery software. This software can often recover data from damaged hard drives.
  4. Finally, if you’ve tried all of these things and you still can’t access your data, you may need to send your hard drive to a data recovery service. These services can often recover data from hard drives that are beyond repair.While having a hard drive fail can be a frustrating experience, there are things you can do to minimize the damage and get your data back. With a little bit of effort, you can often recover your valuable data.

If you’re worried about data loss in the future, you can take some steps to protect your data. Backing up your data regularly is the best way to protect against data loss. You can use an external hard drive, a cloud backup service, or a local backup service. And if you’re worried about hard drive failure, you can use a RAID array to protect your data.

Signs your hard drive is failing;

  1. Making strange noises
  2. Not being recognized by your computer
  3. Files are corrupt or inaccessibleIf any of these things are happening, it’s important to take action right away. The sooner you take action, the more likely you are to be able to recover your data.

How to prevent future data loss;

  1. Backing up your data regularly
  2. Using a RAID array
  3. Servicing the computer systems regularly

By taking these steps, you can protect your data in the event of a hard drive failure.

Identifying a data recovery company;

There are many data recovery companies out there. But how do you know which one to choose?
When choosing a data recovery company in kenya, it’s important to research their success rate and reviews. You should also make sure they have experience with the type of data loss you’re dealing with.

Choosing the right data recovery company can make a big difference in whether or not you’re able to recover your data.

Final thoughts;

While hard drive failures can be frustrating, there are steps you can take to minimize the damage and get your data back. With a little bit of effort, you can often recover your valuable data. By taking these steps, you can protect your data in the event of a hard drive failure.
