Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Asustor also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can regular data verification or checksum processes help maintain data integrity on NAS Asustor LOCKERSTOR 10 devices?

Regular data verification or checksum processes can help maintain data integrity on NAS Asustor LOCKERSTOR 10 devices in the following ways:

  1. Detecting Data Corruption: Regular data verification processes involve checking the integrity of data stored on the NAS device. By comparing the checksum or hash value of the stored data with the expected value, any data corruption or tampering can be identified. This helps ensure the accuracy and reliability of the stored data.
  2. Preventing Silent Data Corruption: Silent data corruption refers to the situation where data gets corrupted without any notification or error messages. Regular data verification processes can help identify such corruption by comparing the checksums of the stored data with the expected values. This enables users to take corrective actions before the corrupted data causes any issues.
  3. Identifying Storage Media Errors: NAS devices like Asustor LOCKERSTOR 10 use various storage media like hard drives or SSDs. These storage media can sometimes develop errors or bad sectors, leading to data corruption. Regular data verification processes can help identify such errors by comparing the checksums of the stored data. This allows users to replace the faulty storage media and prevent further data corruption.
  4. Ensuring Data Consistency: Data verification processes can help ensure the consistency of data stored on the NAS device. By regularly verifying the checksums or hashes of the stored data, any inconsistencies or discrepancies can be detected. This helps maintain data integrity and prevents data loss or corruption.
  5. Early Detection of Data Integrity Issues: Regular data verification processes allow for the early detection of data integrity issues. By comparing the checksums or hashes of the stored data, any discrepancies or errors can be identified before they cause significant problems. This enables users to take timely actions, such as restoring data from backups or repairing corrupted files.

Overall, regular data verification or checksum processes play a crucial role in maintaining data integrity on NAS Asustor LOCKERSTOR 10 devices. They help detect data corruption, prevent silent data corruption, identify storage media errors, ensure data consistency, and enable early detection of data integrity issues.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS LOCKERSTOR 10 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.
