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 Buffalo 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.
How can file system corruption impact data integrity on NAS Buffalo LinkStation LS-WSX500L/R1 devices?
File system corruption on NAS Buffalo LinkStation LS-WSX500L/R1 devices can have a significant impact on data integrity. Here are some ways it can affect the device:
- Data loss: File system corruption can lead to the loss of data stored on the NAS. This can happen when the corruption affects the file allocation table, directory structure, or the actual data blocks. In severe cases, it may render the data inaccessible or completely unrecoverable.
- Data inconsistency: Corruption in the file system can cause inconsistencies in the stored data. This means that the data may become fragmented or contain errors, leading to incorrect or incomplete information. This can impact the reliability and accuracy of the stored data.
- Unreliable backups: Many NAS devices rely on regular backups to ensure data safety. However, if the file system is corrupted, it can affect the backup process and result in unreliable or incomplete backups. This can make it difficult to restore the data to its original state in case of data loss or corruption.
- System instability: File system corruption can cause the NAS device to become unstable or unresponsive. It may result in frequent crashes, freezes, or errors. This can disrupt normal operations and cause inconvenience to users.
- Reduced performance: Corruption in the file system can lead to degraded performance of the NAS device. It may result in slower read/write speeds, increased latency, or longer access times. This can impact the overall efficiency and productivity of the device.
To mitigate the impact of file system corruption on data integrity, it is important to regularly backup data to an external storage device or cloud service. Additionally, performing regular file system checks and maintenance, such as running disk checks or using tools provided by the NAS manufacturer, can help identify and repair any file system issues before they lead to data corruption.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS LinkStation LS-WSX500L/R1 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 Buffalo LinkStation LS-WSX500L/R1. 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 Buffalo
LinkStation LS-WSX500L/R1 has 1 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- 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 Buffalo LinkStation LS-WSX500L/R1 network-attached storage keeps OS Linux 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.

The Buffalo LinkStation LS-WSX500L/R1 devices typically use the XFS file system, which is a high-performance file system designed for Unix-like operating systems. XFS is known for its scalability and ability to handle large amounts of data efficiently.
In terms of data recovery, the XFS file system does not have any inherent limitations or issues that would significantly affect the recovery process. However, data recovery can still be challenging if the device experiences hardware failures or logical errors.
If you encounter data loss on a Buffalo LinkStation LS-WSX500L/R1 device, it is recommended to consult professional data recovery services that specialize in NAS devices to maximize the chances of successful recovery.
