由人工智能和领英社区提供技术支持

If you have a RAID array or a virtual disk that contains important data, you might encounter a situation where the partition table is damaged or lost. The partition table is a data structure that stores information about the partitions on a disk, such as their size, type, and location. Without it, your operating system cannot access or recognize your data. How do you recover partition table from a RAID array or a virtual disk? In this article, we will explain some steps and tools that can help you restore your partition table and recover your data.

1 Identify the RAID parameters

Before you can recover the partition table, you need to know the RAID parameters of your array or virtual disk. These include the RAID level, the number and order of disks, the stripe size, and the parity type. Depending on how your RAID was configured, you might be able to find these parameters in the BIOS, the RAID controller, or the disk management software. If not, you can use some tools that can scan and detect the RAID parameters, such as ReclaiMe Free RAID Recovery or R-Studio.

To recover a partition table from a RAID array or virtual disk: 1) Use RAID management tools to identify RAID level, stripe size, and disk order. 2) Deploy tools like TESTDISK to create a new virtual disk structure. 3) Perform a deep scan to locate lost partitions. TESTDISK can automatically rebuild damaged partition tables. 4) Confirm the detected partitions and write the new table to disk. 5) Validate recovered partitions with disk verification tools. Once satisfied, back up data before any further modifications. The above steps ensure a secure recovery process.

Recovering a partition table from a RAID array or a virtual disk can be a complex process and requires careful handling to avoid data loss. Here are general steps to attempt the recovery. Please note that these steps may vary based on the specific RAID level, file system, and the tools available. Always consult the documentation of the tools you are using and consider seeking assistance from a professional data recovery service if the data is critical. Precautions: Backup: Before attempting any recovery, ensure you have a backup of the original RAID array or virtual disk. This helps prevent data loss in case the recovery process doesn't go as planned. Documentation: Understand the RAID level, disk order, and partition information

2 Create a disk image

The next step is to create a disk image of your RAID array or virtual disk. A disk image is a file that contains an exact copy of the disk data, including the partition table. Creating a disk image can help you avoid further damage to your original disk and work on a safe copy. You can use some tools that can create disk images from RAID arrays or virtual disks, such as DDRescue or DMDE.

3 Scan the disk image

Once you have a disk image, you can scan it for the partition table and the data. You can use some tools that can recover partition tables from disk images, such as TestDisk or Active@ Partition Recovery. These tools can analyze the disk image and find the lost or damaged partition table entries. They can also display the partitions and the files that they contain, and allow you to copy or restore them to another location.

4 Repair the partition table

After you have scanned the disk image and found the partition table, you can repair it and write it back to the original disk. You can use some tools that can repair partition tables from disk images, such as GParted or DiskGenius. These tools can edit the partition table entries and fix any errors or inconsistencies. They can also resize, move, or create new partitions if needed.

5 Verify the data

The final step is to verify that your data is accessible and intact after repairing the partition table. You can use some tools that can check the data integrity and consistency, such as CHKDSK or WinHex. These tools can scan the disk and detect any bad sectors, corrupted files, or missing data. They can also repair some minor issues or recover some deleted data if possible.

6 Backup your data

As a precaution, you should always backup your data regularly and keep multiple copies on different devices or locations. This can help you prevent data loss or minimize the impact of a partition table failure. You can use some tools that can backup your data from RAID arrays or virtual disks, such as Macrium Reflect or EaseUS Todo Backup.
