Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Lenovo often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can implementing user quotas or permissions help prevent accidental data loss on NAS Lenovo ThinkSystem SN550 V2 Blade Server devices?

Yes, implementing user quotas and permissions can help prevent accidental data loss on NAS Lenovo ThinkSystem SN550 V2 Blade Server devices. User quotas allow administrators to allocate a specific amount of storage space for each user, ensuring that they cannot exceed their allocated limit. This helps prevent accidental deletion or overwriting of data by users.

Additionally, setting up appropriate user permissions ensures that only authorized users have access to specific files or directories. By granting read-only or restricted access to certain files, the risk of accidental data loss is reduced.

Furthermore, regular backups and data replication can be implemented to provide an additional layer of protection against accidental data loss. By regularly backing up data to separate storage devices or off-site locations, organizations can quickly recover data in case of accidental deletion or other data loss incidents.

Overall, a combination of user quotas, permissions, and backup strategies can significantly reduce the risk of accidental data loss on NAS Lenovo ThinkSystem SN550 V2 Blade Server devices.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS ThinkSystem SN550 V2 Blade Server can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Lenovo ThinkSystem SN550 V2 Blade Server network-attached storage keeps LifeLine operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

      Yes, it is possible to recover data from a NAS Lenovo ThinkSystem SN550 V2 Blade Server device that has been affected by a hardware RAID controller failure. However, the success of data recovery depends on the extent of the failure and the condition of the drives.

      In case of a RAID controller failure, the first step is to replace the faulty controller with a new one. Once the new controller is installed, it may be possible to access the data again. However, if the RAID configuration or metadata is corrupted, additional steps may be required.

      If the RAID configuration is intact but the drives are not accessible, you may need to use data recovery software or consult a professional data recovery service. These experts can analyze the drives, repair any logical errors, and recover the data.

      If the RAID configuration is lost or damaged, you may need to rebuild the RAID array. This involves recreating the RAID configuration and restoring the data from backups, if available. If backups are not available, a data recovery service may be able to reconstruct the RAID configuration and recover the data.

      It is important to note that data recovery from a failed RAID system can be complex and time-consuming. It is recommended to seek professional help from data recovery experts who have experience in dealing with RAID failures to increase the chances of successful data recovery.
