A Comprehensive Guide to Recovering Data from Damaged RAID 0, 1, 5, 10 [Solution Found]

What Are RAID Levels 0, 1, 5, and 10?

RAID stands for Redundant Array of Independent Disks. When RAID is implemented in a storage system, it allows you to connect two or more drives within the system, so they function as a single, high-speed large volume drive. Alternatively, you can configure them as a single system drive that automatically duplicates (or mirrors) your data for real-time backup.

RAID 0

RAID 0 provides disk striping across all drives in the RAID drive group. It does not offer data redundancy, but it delivers the highest performance among all RAID levels. RAID 0 breaks data into smaller segments and distributes these segments evenly across each drive in the drive group.

RAID 1

The system is set to data protection mode, where the storage capacity is split into two equal halves. One half is utilized for storing your data, while the other half is dedicated to creating a duplicate copy. Should one drive fail, your data remains secure as it has a redundant copy.

RAID 5

It gives you the best of both worlds: fast performance from striping data across all drives, and data protection by dedicating a quarter of each drive in a four-drive system to fault tolerance, leaving three-quarters of the system capacity available for data storage.

RAID 10, also known as RAID 1+0 or RAID 0+1, is a redundant array of independent disks configuration that combines the features of both RAID 1 (mirroring) and RAID 0 (striping). In this setup, data is striped across multiple disk drives in a RAID 0 configuration for improved performance, while an identical copy of the data is mirrored on another set of drives for redundancy. This provides both speed and data protection, as losing one drive in each mirror set will not result in data loss.

Delivers very high I/O rates by striping RAID 1 (mirrored) segments. This RAID mode is ideal for business-critical database management solutions that demand maximum performance and high fault tolerance. A system configured in RAID 10 will provide a total capacity that is half of all the drives in the array.

"Broken RAID Recovery Software - Exceptional Features"

RAID is a sophisticated data storage technology that combines multiple disks into a single logical unit. As a result, many believe that RAID data recovery is equally intricate. Indeed, employing conventional methods can make RAID data recovery quite challenging. It typically involves extracting the disks, reconstructing the RAID configuration, and subsequently connecting it to your computer to retrieve the data.

Things become significantly simpler when you utilize NAS data recovery software. There's no need to remove the hard drive or reconstruct the RAID array. All that's required is to employ a reliable data recovery software. Simply download and run the software, and then allow it to scan your NAS server. This method offers numerous advantages.

• Designed to recover software and hardware RAID
• Recovers files from RAID such as Synology, Western Digital, Dell, etc.
• Recovers files from damaged RAID 0, RAID 1, RAID 4, RAID 5, RAID 10 configurations.
• The recovery process overrides Windows limitations.

How to Recover a Broken/Failed RAID 0, 1, 5, 10

Here are the steps to recover data from a broken, damaged, or failed RAID 0, 1, 5, or 10 setup. Follow these instructions to retrieve your data from the compromised RAID configuration: 1. **Ensure Safety**: First and foremost, disconnect the RAID array from the power source to prevent further damage. 2. **Assess the RAID Type and Issue**: Identify the type of RAID you're dealing with (RAID 0, 1, 5, or 10) and determine the nature of the problem. Is it a hardware failure, software issue, or a single disk failure? 3. **Backup Remaining Healthy Disks**: If possible, create images or clones of the undamaged disks in the RAID to work with, so you don't risk further damaging the original data. 4. **RAID 0 Recovery**: For RAID 0, which has no redundancy, you'll need both drives to recover data. If one drive is damaged, use specialized data recovery software to attempt to rebuild the data from the remaining drive. 5. **RAID 1 Recovery**: RAID 1 mirrors data across two disks. If one fails, replace the faulty disk with a new one and let the array rebuild itself. You should then be able to access the data on the healthy drive. 6. **RAID 5 Recovery**: RAID 5 uses parity information for fault tolerance. With one disk failed, replace the faulty disk and initiate a rebuild. If the RAID controller can't rebuild, use data recovery software to help rebuild the array. 7. **RAID 10 (1+0) Recovery**: RAID 10 combines mirroring and striping. With one pair of mirrored disks failed, replace the faulty disks and allow the array to rebuild. If issues persist, use data recovery tools. 8. **Professional Assistance**: If you're not comfortable with the process or if the data is critical, consider hiring a professional data recovery service. 9. **Data Extraction**: Once the RAID is accessible, use data recovery software like Recuva, tools Data Recovery Wizard, or Disk Drill to scan and extract the lost files. 10. **Verify and Restore**: After the data is recovered, verify its integrity and restore it to a safe location. Remember, prevention is key. Regularly back up your data to minimize the impact of future failures.

Method 1: Run NAS Data Recovery Software

Step 1. Select a NAS server and begin recovery.

Download and install the tool "Data Recovery Wizard" on your Windows 11/10 64-bit computer. Upon opening the software, select "NAS Recovery". The software will automatically list all NAS servers; choose the target NAS device and click "Scan".

Step 2. Enable the SSH service on the NAS server.

Navigate to "Control Panel > Terminal & SNMP," and enable the "SSH service" option. Note the port number for remote access. Launch the Data Recovery Wizard and click "Next."

Step 3. Connect to the NAS server remotely. Connect to the Network Attached Storage (NAS) server from a remote location.

This software will automatically detect your IP address and Port. All you need to do is enter the username and password. If the IP address or Port is incorrect, you can manually adjust it. Afterwards, click "Connect Now."

Step 4. Recover Lost/Deleted NAS Data

Then, the data recovery tool will connect to your NAS and initiate a scan of the NAS device. Following the scan, you will be able to view all the deleted, lost, or existing files on your NAS server.

You can utilize the "Filter" function or opt for the "Search files or folders" option to locate the missing files on the hard drive. Select the desired NAS files that you lost on the server and click "Recover" to save them to another location.

Click the "Recover" button to retrieve deleted NAS files.
