RAID 0 Data Recovery - How to reclaim your data?

In this article, we will discuss the process for a RAID 0 data recovery and the steps to prevent data loss during the rebuilding process.
Data loss in a RAID 0 can cause as much damage to a business as well as for consumer use. The possibility of a sudden data loss could be way more baffling when you don’t have the knowledge of how to deal with it.

For better upkeep of the RAID 0 data, it is important to analyze the particulars of a RAID 0 data recovery, which you will find listed below.

In this article, we will discuss the data recovery process for a RAID 0 and the steps to prevent data loss during the rebuilding process. We also talk about evaluating the particulars of a RAID 0 drive failure scenario to assess the condition of the array when needed.

Factors to keep in mind during a RAID 0 data recovery process:

If at any time you sense something wrong with your RAID 0 array, it is suggested to shut down the system to avoid more damage to the operating system and to seek out professionals with data experience in the recovery of RAID array disks.

At times, when a member disk fails, restore the disks before continuing with the data recovery process, because disk failures can destroy the entire volume. This happens due to the fragmentation of the information already written to the block.

The number of member disks in a RAID 0 will determine the number of fragments the storage will be divided into. Therefore, a single fragment is written to their respective hard drives at once. This makes recovery possible for smaller sections of the RAID 0 data from the member disks.

To recover data from RAID 0, it is important to keep all the member disks handy, reset the member disks, and configure the disks again with the same settings and correct disk order during RAID recovery. Identify the lost or damaged partition in the disk and recover data from the lost partition and reboot.

Too many bad sectors in the RAID hard drive will lead to corrupted data. So that the disks in the array function optimally all the time, it is also essential to keep them in good condition.

The process of RAID recovery depends upon factors like

  • The size of the hard drives
  • The RAID 0 structure
  • The number of disks in the array

It is possible to recover data using data recovery software. However, data recovery software could turn out to be a nightmare if not employed properly and may cause damage to the extent of a strenuous RAID 0 data recovery process. Disk failure, slow performances, etc. could be the resulting after-effects.

Hence, it can be concluded that a call for professional help is more efficient and reliable for RAID recovery than recovery software.

TTR Data Recovery, with their expertise, can help in RAID recovery from failed member disks securely and confidentially.

Steps to prevent data loss during the rebuilding process

  • Before you start a rebuilding process make sure to keep a reliable image of your data. In case data is deleted in the rebuild process, a backup will come in handy.
  • Restore the data on an external volume. This ensures that the files are in proper condition before the data is overwritten to the currently active volume.
  • Make sure to not create any new files or run applications on the drive that requires recovery. This will only overwrite the files that need recovery.
  • Make sure that when removing the hard drives you keep them in the correct disk order.
  • Further, It is not advised to run repair tools like FSCK and CHKDSK on the affected disks unless a reliable backup is ensured in an external volume. By using the repair tools, there is a possibility of data being overwritten. The tools also come in with the read-only function to check for any corruption issues before a change is made.
  • It is also advised to not use a data recovery software if there is a possibility of data being overwritten on the disks. This could further compromise the data recovery process.
  • When in doubt, seek out professional data recovery services.

RAID 0 drive failure scenarios

What happens when a RAID 0 drive fails?

  • Server failures: while RAID array offers fault tolerance when hardware fails, it is unable to protect server failures which are caused by malware or viruses, human error, or file system corruption.
  • Volume rebuild errors: refer to errors emerging while rebuilding the volume. Latency while rebuilding the volume is one of the main disruptions of performance and might lead to a complete disintegration of the system.
  • Controller failures: a RAID controller can either be a hardware or software used to manage HDDs or SSDs. The RAID controller can experience failures as a result of a power surge, overheating, etc. This could cause booting errors and other problems that will ultimately result in data loss.A RAID controller plays an important role in the configuration of the RAID 0 array. Needless to say, errors in the RAID controllers will lead to array failure.

In case the RAID partitions are damaged or corrupted, you will be unable to access the RAID partitions and their files on the hard drive. This process will be followed by rebuilding the drives again in the RAID data recovery process.

Causes of a RAID 0 failure

Due to the absence of redundancy in the software, it is advised to store relevant data in a RAID 0 AND have a backup of that data, in case a failure occurs and recovery of the data fails. A RAID 0 does not protect against hardware defects, multiple disk failures, power surges, user negligence, etc. Since dealing with such problems by oneself could be difficult, it is essential to keep the RAID 0 array in good condition to avoid needing a RAID recovery.

The different causes of RAID 0 failures are: server failure, volume rebuild error, controller failures, partitioning error, data corruption, viruses, user error, manufacturer, and multiple disk failures.

One of the biggest disadvantages in a RAID 0 is if one member disk drive fails, all the data is lost and only a data recovery firm can help you retrieve it back. Using it for operations and businesses where data is most crucial should be avoided.

The RAID 0 offers great benefits for work operations where better speed and performance are key, such as gaming, video streaming, and cache purposes.

None of the RAID options should be mistaken for a safe backup in a computer. A RAID 0 is a non-redundant option and offers no data security and might cost you your valuable information. A backup comes handy when you want to set up your files in other devices and helps with work continuity during a recovery.
