RAID Partition Recovery [Step by Step] Guide

Summary: The article shares ways to fix inaccessible RAID partitions and recover data from such partitions. Also, it mentions ways to find and restore data from deleted, missing, or undetected RAID volumes and partitions with Stellar Data Recovery Technician software.

RAID partition recovery is a process of recovering inaccessible data from a lost, deleted, or undetected RAID partition or volume. If you have accidentally deleted a RAID partition that contains important data, this guide is for you. You may also follow this guide if a RAID partition is missing or can’t be detected.

Reasons for RAID Partition Loss

RAID partition loss may happen due to logical error caused by various reasons, such as:

Further, due to these reasons, a healthy RAID partition may get corrupt, making it inaccessible and unusable. One way to fix such corrupt RAID partition is to format it. However, formatting a corrupt RAID partition will delete all the data. Thus, if data is important, do not format.

In this article, we have discussed various ways to fix a corrupt or undetected RAID 0, RAID 5, or RAID 6 partition. In addition, we have mentioned steps to recover data from missing, deleted, or inaccessible partitions.

Ways to Perform RAID Partition Recovery

There are several ways to perform RAID partition recovery, based on the cause of partition loss. But before you begin RAID partition recovery, consider the following:

1. Restore RAID Partition via Disk Management Tool

A RAID partition can’t be accessed if the system fails to assign a drive letter due to system-related issues. To check if the RAID partition is without a drive letter, open the Disk Management tool. Then follow these steps to assign a drive letter:

NOTE: If the partition isn’t visible in Disk Management tool, it’s probably deleted.

If it is accessible, back up your data immediately.

In case you see a prompt to format the partition or error such as File system can’t be recognized’, the RAID partition is probably corrupt due to file system error. Follow the next method to repair the file system of a corrupt RAID partition.

2. Repair Corrupt RAID Partition via CHKDSK Scan

CHKDSK or Check Disk scan helps fix file system errors on a corrupt NTFS RAID volume or partition. Follow these steps:

WARNING: CHKDSK isn’t completely safe. It may cause data loss if the disk is old and has too many bad sectors. Run the CHKDSK scan at your own risk.

After repair, try to access the RAID partition. If accessible, copy your files to a safe location. In case of error or CHKDSK fails to fix the corruption, head to the next method.

3. Use a RAID Partition Recovery Tool

A RAID recovery tool such as Stellar Data Recovery Technician not only helps recover data from a RAW or corrupt RAID partition but also retrieves data from deleted or missing RAID partitions, which are not visible in the Disk Management tool.

Before you begin,

Follow these steps:

Based on the provided RAID parameters, the software identifies and constructs a virtual read-only RAID configuration. However, if the entered parameters are wrong, the software automatically detects the RAID factors and constructs a few probable RAID constructions.

Once formatted, transfer the recovered data back to the repaired RAID partition. To avoid such data loss situations, always keep a backup of your RAID data.

Conclusion

Partition loss or corruption in the RAID array may happen due to accidental deletion, human errors, bad sectors, drive errors, abrupt shutdown, crash, etc. While you may try to fix a corrupt RAID partition by using CHKDSK command, there is no way to restore a lost or deleted partition other than using a RAID recovery software.

Software such as Stellar Data Recovery Technician can help find and recover inaccessible data from lost, deleted, or corrupt RAID partition. Also, you can use the software to reconstruct a broken RAID 0, RAID 5, or RAID 6 array.
