RAID is widely used around the world because it improves transmission rates and provides fault tolerance. RAID is used by many businesses to protect the security of sensitive data. Despite this, data loss on RAID disks still occurs. And, according to statistics, RAID data loss accounts for a significant share of all disk array environment data disasters.
RAID data recovery is the first thing that comes to mind when RAID data is lost, regardless of what caused it. Today, we’ll look at how to restore data from a hardware RAID array. People who are experiencing RAID data loss are strongly encouraged to read this article to learn how to complete RAID file recovery and how RAID data loss occurs.
After reading Chapter 1, you’ll be able to handle RAID data loss problems on your own with the help of a third-party tool called Power Data Recovery from MiniTool, which has won acclaim around the world for providing solutions that are precisely tailored to meet the needs of individual users and businesses of all sizes. PCWorld, CNET, and WindowsReports all endorsed the majority of the products.
MiniTool data recovery is a well-known RAID recovery program. In Chapter 2, I’ll primarily cover two topics: the distinctions between hardware and software RAID, as well as the causes of RAID data loss.
Chapter 1 – How to Recover Data from Hardware RAID
Summary: In this section, we’ll go through how to recover RAID data using MiniTool Power Data Recovery, a powerful and simple-to-use recovery application. Even inexperienced users will be able to effectively recover data with this.
Once your vital files/folders are lost due to the following reasons, you should purchase MiniTool Power Data Recovery to scan the RAID drive right away.
- a) Careless deletion: files are accidentally erased from a RAID drive and then deleted from the recycle bin. During disk management, one or more partitions are mistakenly erased.
- b) Damage to partitions: A partition may be damaged as a result of a virus assault, a system crash, or other Its file system may also become RAW at times.
- c) Reformatting: reformatting a partition or the entire disk will delete all data on it, so you won’t be able to access it if you do it
1. Download and run MiniTool Power Data Recovery, then select This PC from the main menu.
2 Next, click Scan and choose the RAID volume from which you want to recover lost files.
3. The detected files will now be displayed one by one in the interface below, where you must pick all of the files you want to recover. If there are too many files to pick from, you can use the Find or Filter functions to reduce the scope of your search.
4. After you’ve picked all of the files you’ll need, press the Save button and choose a safe storage location.
Chapter 2 –A brief comparison of software RAID and hardware RAID
1 Software RAID is built entirely by software (there is no need for the hardware to be actually configured as a RAID drive).
2 Hardware RAID is, at its core, a hardware-based system. However, they serve the same purpose.
Common RAID levels:
RAID 0: RAID 0 is the first RAID mode, based on Data Stripping. It’s also the most basic type of disk array, requiring at least two disks. Despite its low cost, RAID 0 can improve overall disk speed and throughput.
Deficiency: It lacks redundancy and the ability to repair errors.
RAID 1 provides data redundancy and is also known as disk mirroring. The idea is that data is mirrored from one disk to the other. To put it another way, when data is written to one disk, an image file is created and saved on the other drive. This might offer the highest level of system stability and reparability without compromising performance.
Deficiency: only half of the disk capacity is used, resulting in indirect cost increases.
RAID 0+1 (sometimes known as RAID 10) is a RAID 0 and RAID 1 combination. The mirroring of RAID 0 arrays is what RAID 10 is all about. It has the following characteristics:
1 Provide rapid read/write speeds.
2 Provide complete redundancy.
3 The data is spread over numerous disks.
4 Each disk has a physical mirrored disk of its own.
5 Allow data availability to be affected by disk failure.
RAID 5: the parity code is present on all drives in the array, increasing the array’s reliability. Cutting data contained on one drive into chunks and storing them in all disks in the array is the principle. This alleviates the bottleneck problem caused by parity data storage at the cost of speed.
Deficiency: Data transfer parallelism and controller architecture are difficult to manage.
RAID data loss does happen, believe it or not, for a variety of reasons. People will automatically prioritize RAID recovery in this situation. The “How to Recover Data from RAID” section of the tutorial will walk you through the process step-by-step.
