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 TeraStation WS5220DN08S9 devices?

File system corruption can have a significant impact on data integrity on NAS Buffalo TeraStation WS5220DN08S9 devices. Here are a few ways it can affect data integrity:

Data Loss: File system corruption can lead to the loss of data stored on the NAS device. This can occur if the corruption affects critical system files or the metadata that keeps track of file locations and attributes. In some cases, the corrupted files may become inaccessible or completely lost.
Data Inconsistency: Corruption in the file system can result in data inconsistencies, where the stored data does not match the expected values or is in an inconsistent state. This can lead to data errors and inaccuracies, making it challenging to rely on the integrity of the information stored on the NAS device.
Data Access Issues: File system corruption can cause difficulties in accessing or retrieving data from the NAS device. It may result in slow read or write speeds, frequent errors, or even system crashes. These issues can disrupt normal operations and make it challenging to retrieve or modify data reliably.
Data Integrity Verification: File system corruption can also impact the ability to verify data integrity using built-in mechanisms such as checksums or data redundancy techniques. If the corruption affects the integrity checks themselves, it can lead to false positives or negatives, making it difficult to identify and rectify data corruption.
Data Recovery Challenges: In cases of severe file system corruption, data recovery can become a complex and time-consuming process. Depending on the extent of the corruption, specialized tools and techniques may be required to recover the data, and there is no guarantee of complete success.

To mitigate the impact of file system corruption on data integrity, it is essential to regularly back up data stored on the NAS device, implement proper data redundancy mechanisms, and regularly monitor the health of the file system. Additionally, promptly addressing any signs of file system corruption, such as unusual errors or slow performance, can help minimize the potential impact on data integrity.

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

Although the NAS TeraStation WS5220DN08S9 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.
