Though RAID disks appear to be an excellent tool for data backup and storage with high fault tolerance, what if you encounter data loss issues with your RAID disk or volume? The best option is to run a RAID recovery software for Mac to get your data back. Below are some of the primary reasons that may lead to data loss issues in RAID 1:
- • Formatted, inaccessible, corrupted, or logically failed RAID.
• RAID array failure due to malware or virus intrusion.
• Missing or deleted RAID volumes or partitions.
# Part 1 What is RAID and RAID Data Recovery
RAID (Redundant Array of Independent Disks) is used to improve the efficiency and reliability of a computer. While they're less commonly used in personal setups, they can form the basis for incredibly fast server configurations and allow organizations to keep operating in the event of a hard drive failure. In environments where data needs to be accessible at all times and fast read-write speeds are necessary, RAID is a great redundancy solution.
Recovering data from a damaged RAID (Redundant Array of Independent Disks) configuration or infrastructure is known as RAID data recovery. It involves a combination of automated and manual data recovery processes to extract and restore data from one or more RAID disks and storage components. RAID data recovery can be applied to both hardware RAID and software RAID.
RAID data recovery differs from a typical data recovery process because RAID storage configurations use a unique and complex method of storing and removing data. Data recovery is possible for any RAID level, including RAID 0, RAID 2, RAID 3, RAID 4, RAID 5, RAID 6, and RAID 10.
What is the Best RAID Recovery Software for Mac?
When a RAID fails, data is lost and the RAID volume becomes inaccessible. However, RAID disks do not offer direct access or data recovery. Customers find that rebuilding the RAID configuration is the most challenging step in recovering lost data. Fortunately, there are third-party data recovery solutions that can simplify this process.
Choosing a reputable RAID recovery program is highly beneficial for retrieving data from RAID disks! With the help of the Data Recovery Wizard for Mac, you can fully recover RAID data on your Mac. Alternatively, the best RAID recovery software can assist you in restoring data from any RAID hard drive, as long as your computer system can recognize it. This includes RAID 0, RAID 1, RAID 5, and RAID 10. Furthermore, this data recovery software has great compatibility with dynamic disks, RAID configurations, and EXT2/EXT3 file systems.
- It can recover RAID data in case of accidental deletion, file system corruption, RAID formatting, or virus attacks.
- It can restore files from a failed or formatted RAID hard drive.
- It features a file filter that helps you easily narrow down your RAID search results.

Note: Before data recovery, it's recommended to click “Disk Backup” from the left sidebar and create a backup of your HDD/SSD to prevent further data loss. After the backup, the software can restore data from your disk image, and you can use the HDD or SSD again.
Step 2: Browse the scan results
The software will immediately scan the disk volume you've chosen and display images, files, audio, video, and email in the left pane.
Step 3: Select the files and recover them
Click on the data to preview it, then hit the "Restore" button to get it back.
[Software Guide] How to Recover Data from RAID Hard Drive on Mac
If you are familiar with RAID data recovery procedures, you can attempt to manually recover data from a RAID. However, if you are not well-versed with RAID, attempting to restore data from a RAID on your own can lead to permanent data loss. Additionally, you should be aware that data loss can occur during a RAID rebuild. If the RAID is not rebuilt correctly, you risk losing all your data.
Solution 1: Recover data from RAID hard drive on Mac using software
What can you do if RAID data is lost on a Mac? Normally, professional data recovery software would be the easiest way to find and retrieve lost RAID data from a device. As mentioned earlier, tools are available for assistance. Since RAID consists of multiple disks, if the RAID configuration is intact, data recovery software for Mac can retrieve data from the virtual drive created on the RAID.
For you, the process is straightforward:
- • Install Disk Drill for Mac. After the download is complete, save it in a location other than the RAID disk to avoid overwriting any lost data.
• Connect the RAID drive to your computer.
• Once Disk Drill for Mac is open, click the "Search for Lost Data" button and select the RAID drive from the list of available devices.
Solution 2: Recover data from a RAID disk on a Mac using a service
If your RAID is damaged and cannot be scanned by software, try the Online Manual Data Recovery service one-on-one.

Solution 3: Rebuild the RAID manually
You can also rebuild the RAID manually or using software. To avoid data loss, follow these guidelines:
Step 1: Create an image of the backup and RAID setup on a separate disk.
Step 2: Do not create a new RAID on the old hard drive. This could cause data loss.
Step 3: If you do not want the repair tool to remove file pointers and increase the chances of data loss, run the Mac Disk Utility after the backup.
Step 4. Do not add, move, or delete files from the damaged RAID. You can copy or back up the files, though.
Step 5: If you want to keep your drive order correct, don't remove more than one drive at a time.
Step 6: Pay attention to RAID failure notifications when they happen.
Rebuilding a RAID array manually and restoring data can be a challenging task for novice PC users. Depending on your situation, you can utilize remote recovery services or data recovery software to retrieve corrupted or lost files from RAID disks.
Fix 4: Recover RAID Data by Changing Port on Mac
Switching the hard drive ports is a free technique that can help you recover data from a Mac RAID hard drive.
Step 1: Turn off and unplug the RAID system, then remove the hard drives.
Step 2: Mount the drive in a bay and connect it to a SATA, SCSI, or SAS port.
Step 3. Turn on the computer. Make sure that all hard drives are detected by the system. If your computer does not recognize any hard drives, you will not be able to proceed with the recovery.
Why Does RAID Data Loss Happen, and How to Protect It?
Though RAID disks provide higher redundancy and fault tolerance, disk failures do occur occasionally. Data loss can result from either hardware or software-based RAID configurations, leading to:
- Purposeful or accidental deletion of files
- Initiation of formatting the drive while expecting to use NAS RAID disk
- Configuration errors associated with power failures and other human or system errors
- Reference to a corrupted or erroneous RAID configuration
It would be useful to know some tips on how to avoid RAID array failures. After being aware of the common reasons for RAID array failure, it is crucial to take preventive measures to minimize these “causes.”
- First, regularly monitor critical S.M.A.R.T parameters, the health status, and temperature of your hard drive devices. This will allow you to catch signs of RAID array failure early on and address them before they worsen.
- Second, back up your data regularly, as you can never predict when a failure might occur.
- Avoid using RAID operating systems, system files, or firmware in a "beta" state. However, keep your OS and crucial software programs up to date with the latest stable releases. Maintain at least two new or spare hard drives on hand to replace failed drives in the array when needed.
Thus, it's essential to back up a RAID regularly using a reliable backup strategy, such as Mac's Time Machine.
Conclusions
RAID data recovery isn't as difficult as some might think. Essentially, you're recovering data from a hard drive and saving it elsewhere in case your RAID setup starts to fail. Even if you don't have a RAID system, the Data Recovery Wizard for Mac tools and tips in this article can still help with data loss.
