All You Need To Know About Raid Data Recovery

If you are into technology and you know the basics about hard drives and their recovery process, you might have definitely heard about RAID drives. These are a way of storing the same data in different places on multiple physical hard disks. They are known to be very reliable and dependable when it comes to storing crucial data. With the advancement in technology and coming of these exceptional hard drives, storing the data without any hassle has become so convenient.

But, no matter how reliable they are and how advanced the technology gets, no one will ever be able to design a hard drive that has no glitches at all like any other hard drive. RAID hard drive is prone to damage and collapse as well. The process of RAID data recovery is no piece of cake, but if you have a professional by your side, you have nothing to worry about. Before plunging into the recovery process, let us get you familiar with the concept of the hard drive.

What is RAID?

RAID, Redundant Array of Inexpensive disks or Redundant array of Independent risks, is a data storage virtualization technology that allows you to store data in different places on multiple physical hard disks. This is generally to increase your system performance or provide fault tolerance.

Talking about different the levels of RAID

When it comes to RAID hard drives, data is allocated in different ways in there. These different ways are referred to as levels. For instance, there are RAID 0,1,2,3,4,5.6 and 10. Below is the enunciated application of different RAID levels.

  • RAID 0- This is the striped disk array without fault tolerance. RAID 0 provides data striping but without any redundancy. This sure improves but does not deliver fault tolerance. That means if one drive fails, then all the data in the array is lost.

  • RAID 1- This is referred to as the mirroring volume. As it provides disk mirroring. Level 1 is known to deliver twice the read transaction rate of single discs and the same write transaction rate as single disks.

  • RAID 5- This level of the RAID hard drive provides data striping at the byte level and stripe error correction information. This level aims for excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of the RAID. If you wish to avoid complete data loss, it is vital to know how to back up RAID drives to prevent total data loss.

  • RAID 6- This is the level associated with independent data disks with double parity. Raid 6 requires a minimum of four disks. RAID 6 uses two-party stripes on each disk and allows for two disk failures within the RAID set. The double parity makes it provide high fault tolerance and more expensive since the two extra disks required for parity.

  • RAID 10- This level is also called RAID 1+0. This is not one of the original RAID levels. Tow RAID 0 stripes are created, and a RAID 1 mirror is created over them. This level is used for both replicating and sharing data among disks.

Reasons for the increasing popularity of RAID data recovery

With the advancing of technology, RAID hard disks are gaining popularity with each passing second. Apart from higher availability and better storage performance, Raid disks have other benefits as well.

  • Improved parity check- With RAID hard disks, the ability to check for any potential system crash improves to a great extent.

  • Increased speed- Simultaneous reading and writing of data tend to increase the speed.

  • Improved fault tolerance- Raid enables you to create the backup of the data, which is beneficial in the regular running of OS at times when a disk failure occurs.

  • Higher data security- You don’t have to worry about losing your data.

  • Simultaneous reading and writing process- this is one of the most significant reasons why RAID hard drives are getting so popular.

Apart from all the right things said about The Raid hard disk, it is prone to breakdowns and collapses as well as other hard drives. Raid hard disk data recovery is a bit more complicated as compared to other data recoveries and comes with a truckload of risks. There are a plethora of logical and physical reasons behind the crashing of the hard drive. Let us check them out.

  • Issues with Raid controller- A single controller in raid hard disk is responsible for directing several operations. Due to abrupt power surges boot issues would prevail that might lead to data loss

  • If the drive falls out- The hard drive falling generally occurs in Raid 0. Raid 0 undergoes damage every time a failure occurs in one of the member disks. Logical issues like accidental formatting can be one of the reasons for the loss. If you face such problems, it is recommended to get the drive repaired and the data recovered by some professional and reliable experts.

  • Bad sectors- The collapse of the hard drive due to failure of one sector would lead to the damage of an entire array. And if that happens, the recovery would be an impossible task to achieve. Professional help is needed at times like these.

  • Issues with the server- Inaccessibility of the data can occur if the server undergoes a complete crash. This is one of the significant reasons why you might not be able to access your data.

How To Recover Data From Hardware RAID?

As reliable and advanced as these RAID drives are, they even are prone to technical glitches and issues. Also though it is believed that RAID arrays should not fail due to their fault-tolerance and auto=rebuild capabilities, that is the reason why people neglect taking the backup of their RAID files. And this can lead to inevitable data disaster. You might end up losing the most crucial data. The following steps are sure to help you to recover data from RAID 0, RAID 5, and RAID 6 drives effortlessly.

Data recovery from a Raid array after accidental deletion

There can be numerous instances which may lead to unintentional deletion of crucial data. Raid data recovery software all around the world can help in recovering data even from a corrupted, inaccessible, RAW, or formatted partition.

  1. After starting any authorized recovery software that you have installed on your computer, choose the option ‘This PC’ on it.

  • Data recovery from a Raid array after accidental deletion

  • There can be numerous instances which may lead to unintentional deletion of crucial data. Raid data recovery software all around the world can help in recovering data even from a corrupted, inaccessible, RAW, or formatted partition.

  • After starting any authorized recovery software that you have installed on your computer, choose the option ‘This PC’ on it.

  • In this step, you can click on the ‘Settings’ button on the right bottom of the screen to scan and show the specified types of files. This step saves time and reduces the hassle of spending almost all day searching for the data that need to be recovered. The file systems and the file types need to be selected to facilitate easy recovery.

  • Now the next step would be selecting the partition which was used to store the deleted files from the partition list given. After thorough scanning from the data you wish to recover, click on the ‘Save’ button to recover all those files.

Recovering RAID data from lost partition

  • After starting the software, you need to select ‘Hard disk drive’ or ‘removable disk drive.’

  • Two things need to be done in this step. The first one of them is to select the disk that includes lost partition. And the next thing would be to press the scan button to detect files in the selected disk.

  • After the thorough scan and selecting all the files you want to recover, press the save button so that Raid hard disk data recovery begins.

Summing it up

All the professional hard drive recovery services recommend that you should check RAID drives once in a while for mechanical issues, smart errors, and optimization. You can either perform these checks manually or take help from a tool. These checks help you safeguard your RAID array against many causes of Raod failure.

There are a plethora of recovery tools that can help recover your data in a jiffy. If you are thinking of plunging into the recovery yourself, make sure you have an expertise in the field.
