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 QNAP 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 data storage capacity limitations that can impact data loss risks for NAS QNAP TVS-882ST2 devices?

Yes, there are data storage capacity limitations that can impact data loss risks for NAS QNAP TVS-882ST2 devices. Some of the limitations include:

Drive Capacity: The QNAP TVS-882ST2 supports up to 2.5-inch SATA SSDs or HDDs with a maximum capacity of 10TB per drive. If you exceed this capacity, the device may not be able to recognize or utilize the additional storage.
RAID Configuration: The TVS-882ST2 supports various RAID configurations, such as RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD. However, the choice of RAID configuration affects the overall storage capacity and data redundancy. For example, RAID 1 mirrors the data across drives, reducing the overall capacity but providing redundancy in case of drive failure.
File System Limitations: The TVS-882ST2 supports different file systems like EXT4, NTFS, and FAT32. Each file system has its own limitations, such as maximum file size and maximum volume size. Exceeding these limitations can lead to data loss risks.
Backup and Redundancy: It is crucial to have a proper backup strategy and redundancy in place to mitigate data loss risks. The TVS-882ST2 supports various backup options, such as local backup, remote replication, and cloud backup. Implementing a backup plan ensures data can be recovered in case of device failure or data corruption.

It is important to carefully consider these limitations and plan your storage configuration accordingly to minimize the risk of data loss. Regular backups and monitoring of the device's storage capacity are recommended to ensure data integrity and availability.

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

Although the NAS TVS-882ST2 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.

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 QNAP TVS-882ST2 network-attached storage keeps QTS (QuTS hero) 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.

  It is always recommended to keep your NAS device's firmware up to date to ensure optimal performance and security. However, when it comes to data recovery, firmware updates or patches may not directly impact the recovery process. Data recovery from a NAS device usually involves accessing the storage drives directly, bypassing the NAS firmware.
  That being said, if you are experiencing any issues with your QNAP TVS-882ST2 NAS device, it is advisable to check the QNAP support website or contact their customer support for any available firmware updates or patches that might address the specific issues you are facing.
