The reasons for RAID recovery are similar to those for regular hard drive data recovery. RAID failure or corruption can be caused by human error, hardware or software malfunction, malware infection, mechanical failure, power issues, bad sectors, or an abrupt system shutdown. However, when it comes to recovering a damaged RAID, the situation is different.
When RAID is damaged, the RAID volume becomes inaccessible and data gets lost. However, you can't directly access or retrieve data from the RAID hard drives. You need to rebuild or reconstruct the RAID configuration to recover the lost data, which is the most difficult part for users. Luckily, there're many third-party data recovery tools that can help you simplify this process. Read on for more details.

How to Recover Data from a RAID Hard Drive
Don't hesitate to equip your computer with this powerful tool. With the software, you can recover files from a RAID hard drive in 3 simple steps:
Scan the disk > Preview and select the files you need > Recover data.
Here are the steps to recover RAID data using the Data Recovery Wizard tool:
Step 1: Scan the RAID drives
Select the RAID disk from which you want to recover data and click “Scan”. Wait for the scanning process to complete; your deleted files will be displayed one by one.
Step 2: Search and Preview Lost RAID Files
You can use the “Filter” for quick navigation to find your deleted or lost files. Additionally, you can search for missing RAID drive files by file name or file extension.
Step 3: Recovery of lost RAID drive files
Select the files you need, and click “Recover.” Browse and save these files to another secure location.

## General RAID Information
Before introducing professional RAID data recovery software, let's learn some basics about RAID.
RAID stands for "Redundant Array of Independent Disks," which in Chinese can be translated as "Independent Redundant Disk Array." It is a data storage technology that combines multiple hard disks to provide data redundancy, improved performance, or both. Depending on the specific RAID level (such as RAID 0, RAID 1, RAID 5, RAID 6, and so on), different functionalities and levels of protection are achieved. For instance, RAID 0 enhances read and write speeds but does not offer data redundancy, while RAID 1 provides data mirroring to ensure data safety.
RAID, acronym for Redundant Array of Independent Disks or Redundant Array of Inexpensive Disks, is a data storage virtualization technology that combines multiple physical disk drive components into a logical unit for the purposes of data redundancy or performance improvement by storing the same data in different locations on the drives.
Different Levels of RAID
The different ways data is striped across RAID disks are called RAID levels, which include RAID 0, 1, 2, 3, 4, 5, 6, and 10. Here's an explanation of some of the most common RAID levels:
| Level | Definition |
|---|---|
| RAID 0 | (Striped Disk Array without Redundancy) RAID 0 provides data striping (spreading the blocks of each file across multiple disk drives) but no redundancy. This improves performance, but offers no fault tolerance. If one disk fails, all data in the array is lost. |
| RAID 1 | (Mirrored Volume) RAID 1 provides disk mirroring. Read transactions at Level 1 are twice as fast as a single disk, and write transactions have the same speed as a single disk. |
| RAID 5 | (Byte-Level Distributed Parity) RAID 5 provides data striping at the byte level and also parity information for stripe error correction. This delivers excellent performance with good fault tolerance. RAID 5 is one of the most popular RAID implementations. Given its popularity, it's crucial to know how to back up RAID drives to avoid total data loss. |
| RAID 6 | (Dual Parity Independent Data Disks) RAID 6 requires a minimum of four disks. It uses two parity stripes per disk, allowing for two disk failures in the RAID set. Dual parity gives it high fault tolerance but also higher cost, as two additional disks are needed for parity. |
| RAID 10 | (Striped Mirrors) RAID 10 (also called RAID 1+0) is not an original RAID level; it creates two RAID 0 stripes and mirrors them with a RAID 1. Used for replicating and sharing data between disks. |
The advantages of RAID (Redundant Array of Independent Disks) include: 1. **Data Redundancy**: RAID provides data backup and protection by distributing data across multiple hard drives. If one drive fails, the data can be restored from others, enhancing system reliability. 2. **Performance Boost**: RAID increases I/O speed and data transfer rates by striping data across multiple drives, thus improving system performance. 3. **Capacity Expansion**: RAID allows multiple smaller disks to be combined into a single large logical drive, offering greater storage capacity. 4. **Cost Efficiency**: While RAID requires multiple disks, it can be more cost-effective than purchasing a single high-capacity, high-performance drive, especially in enterprise-level storage solutions. 5. **Flexibility**: RAID has different levels (such as RAID 0, 1, 5, 6, 10, etc.), each with varying performance, redundancy, and cost characteristics, allowing for customization based on specific needs. 6. **Fault Switching**: Certain RAID configurations (like RAID 1 and RAID 10) support hot spare disks, automatically switching to a standby drive when a primary one fails, ensuring uninterrupted operation. 7. **Data Recovery**: Under RAID, data can be reconstructed even after a disk failure through a specific recovery process, reducing the risk of data loss. 8. **Load Balancing**: RAID balances the workload across disks, prolonging their lifespan and minimizing the likelihood of failures due to individual disk overloads. 9. **Backup Solution**: RAID 1 (Mirroring) provides real-time backup with data synchronized across two drives, eliminating the need for an additional backup system. It's important to note that while RAID offers numerous benefits, it does not entirely replace data backup. Comprehensive data protection also requires regular offline or cloud backups.
RAID is typically used to improve the overall system performance for computer users, especially server users, by using multiple disks in cooperation. It also offers the following benefits:
- Improved data security
- Greater fault tolerance
- Enhanced parity checking and regular checks to prevent system crashes
- Simultaneous read and write operations
However, despite the higher level of data security that RAID provides, data loss on RAID hard drives can still happen. You may suffer data loss on your RAID disk or drive due to system crashes, virus attacks, power failures/surges, or other unexpected errors. You might think that RAID data recovery is complicated. As long as you have the right RAID recovery software, you can easily, safely, and effectively recover data from RAID hard disks.
