Top 5 ways to recover data from failed RAID 5; all you need to know.
Are you worried about your failed RAID 5 and how to recover your data from it? Then, you are at the right place. In this article, you’ll get to know all about failed RAID 5 and how to recover data from your failed RAID 5.
Redundant Array of Independent Disks, commonly known as RAID, is built up of configuration of multiple hard drives into logical units to improve the performance of RAID and redundancy of RAID data. This is the key reason why RAID storage systems are widely used in business organizations to store data.
Types of RAID modes :
RAID 0 — It is striped disks. In RAID 0, data is divided equally between two or more drives but, if one or more drives fails, this leads to failure of the RAID array. RAID 0 is a large size and fastest speed RAID array, while the only disadvantage is that it has no redundancy.
RAID 1 — It is mirrored disks. In RAID 1, two or more drives contain identical data on them. The advantage of RAID 1 is that single drive failure will not result in an entire RAID data failure, but on the other hand, it has one disadvantage, speed and size are limited, slowest and smallest among all other RAID modes. To recover RAID 1, only one drive is needed.
RAID 3 — striped set with dedicated parity. In RAID 3, data is equally split into two or more drives, and additionally, a dedicated parity drive for storage is also available. It is a high-speed drive for reading and writing operations. It performs poorly while multiple instructions are given at the same time.
RAID 5 — striped disks with distributed parity. Data is divided evenly into two or more disks, and parity is split between disks. RAID 5 is large in size, high speed and redundant.
RAID 10 — striped set of mirrored parity. In RAID 10, four or more drives are made into two striped mirrors.
What are the causes of RAID failure?
There are multiple causes of RAID data failure, but one should know that RAID is a storage system, not a backup. Here is the list of important things to consider to prevent RAID data failure:
Logical cause of failure
1 . RAID configuration issues arise due to an improper set of hard drives in the 2. RAID array, which causes RAID data failure.
3. Files, folders and documents get corrupted accidentally.
4. Frequent virus and malware attacks
5. Sometimes RAID data fails due to damage of one or multiple hard drives.
Human error
1 . Accidental deletion of files and folders can lead to a RAID failure
2. Improper reformatting of RAID hard disk drives
3. Improper placement of drives also result in RAID failure
Physical failure
1 . Failure of RAID controller
2. RAID server data crashes
3. Bad sectors
4. Failed motherboard
5. RAM and multiple hard drives failures
What are the causes of RAID 5 failure?
RAID 5 is a disk striping with parity. It consists of three drives which make RAID 5 work faster and more efficiently. It can handle a single drive failure more than that can fail RAID 5. When a single disk fails in a RAID 5 disk, the disk array working speed reduces and simultaneously, it leads to failure of drives. The disk array still functions because the data on the failed disk can be rebuilt using parity. RAID controllers can rebuild the disk if the hot-spare disk is available, and if not, replacing the failed disk would be better.
What is the procedure to recover RAID 5?
1 . If you are susceptible to a RAID failure, run the IP config utility.
2. Until the recovery is completed, select ‘ Work with the disk.’
3. Third step, select Rebuild disk unit data’.
4. Select the disks you want to rebuild; once you select, press Enter.
5. Suppose you do not want to restore data; type q to cancel in any complex
6. situation. And to prevent complicated situations, you can connect with professional data recovery services.
Conclusion :
As discussed above, there are different modes of RAID, and different RAID modes have their advantages and disadvantages. However, in the case of RAID 5, we are fortunate enough to recover its data but in any complicated scenario connecting with a professional data recovery service, like Techchef, a data recovery service company that provides reliable and trustworthy services.
