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.
Are there any known issues or limitations when using NAS Lenovo ix4-200d devices with virtualization platforms such as VMware or Hyper-V?
Yes, there are some known issues and limitations when using NAS Lenovo ix4-200d devices with virtualization platforms such as VMware or Hyper-V.
- Limited Performance: The Lenovo ix4-200d is a low-end NAS device, and its performance may not be sufficient for running virtual machines with high resource demands. It may not be suitable for running multiple virtual machines simultaneously or handling heavy workloads.
- Limited Storage Capacity: The ix4-200d has a maximum storage capacity of 8TB, which may not be sufficient for storing large virtual machine files or snapshots. This limitation can impact the number and size of virtual machines that can be hosted on the device.
- Limited Scalability: The ix4-200d is designed for small-scale environments and may not provide the scalability required for larger virtualization deployments. It may not support advanced features like clustering or high availability.
- Limited Integration: The ix4-200d may not have direct integration with virtualization platforms like VMware or Hyper-V. It may not support features like VAAI (VMware vStorage APIs for Array Integration) or Microsoft's VSS (Volume Shadow Copy Service), which can impact the efficiency and functionality of virtual machine management.
- Lack of Advanced Data Protection: The ix4-200d may not provide advanced data protection features like snapshotting, replication, or backup integration with virtualization platforms. This can limit the ability to protect and recover virtual machines in case of data loss or hardware failures.
It is recommended to carefully review the specifications and capabilities of the Lenovo ix4-200d NAS device and consider these limitations before using it with virtualization platforms.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS ix4-200d 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:
-
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.
-
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.
-
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
-
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.

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Lenovo ix4-200d. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.
How to recover data from a Lenovo
ix4-200d has 4 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- JBOD;
NAS supports:
- exFAT, VFAT, FAT 12 / 16 / 32;
- NTFS / ReFS;
- APFS / HFS+;
- Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
- VMFS / HikvisionFS;
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:
-
Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
-
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
-
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.

-
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?
The Lenovo ix4-200d 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, data recovery from a Lenovo ix4-200d NAS device can be done in cases of RAID system failures. However, the process may vary depending on the specific circumstances and the severity of the failure.
In cases of RAID system failures, it is important to immediately stop using the NAS device to prevent further damage and data loss. It is recommended to contact a professional data recovery service that specializes in RAID recovery to assess the situation and provide appropriate solutions.
The data recovery process for a RAID system failure typically involves repairing or rebuilding the RAID array, recovering the data from the failed drives, and then reconstructing the data to make it accessible again. This process can be complex and time-consuming, so it is crucial to rely on experts who have experience and knowledge in RAID recovery.
It is important to note that the success of data recovery in RAID system failures depends on various factors such as the extent of the damage, the availability of spare drives, and the expertise of the data recovery service.
