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 D-Link 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 does a NAS D-Link DSM-600 device store and manage data?

The D-Link DSM-600 is a Network Attached Storage (NAS) device that is designed to store and manage data in a network environment. Here is how it typically stores and manages data:

  1. Storage Capacity: The DSM-600 comes with multiple hard drive bays that allow you to install one or more hard drives. These hard drives provide the storage capacity for your data. The device supports various RAID configurations, including RAID 0, 1, 5, 6, and 10, which offer different levels of data redundancy and performance.
  2. File System: The DSM-600 uses a file system to organize and manage data on the installed hard drives. It typically supports file systems like EXT4, which is a widely used file system in Linux-based NAS devices. The file system allows for efficient storage and retrieval of data.
  3. Network Connectivity: The DSM-600 connects to your network via Ethernet, allowing multiple users or devices on the network to access and manage the stored data. It supports different network protocols like SMB/CIFS, FTP, and NFS, enabling various devices and operating systems to access the NAS.
  4. User Access and Permissions: The DSM-600 provides user access control and permission management features. It allows you to create multiple user accounts and assign different access rights and permissions to each user. This ensures that only authorized users can access specific files or folders on the NAS.
  5. Data Backup and Synchronization: The DSM-600 often includes built-in backup and synchronization features, allowing you to schedule automatic backups of your data to external storage devices or cloud storage services. This helps to protect your data from accidental loss or damage.
  6. Web-based Interface: The DSM-600 is typically managed through a web-based interface that can be accessed from any device with a web browser. This interface provides a user-friendly dashboard to configure settings, manage storage, create user accounts, and perform other administrative tasks.

Overall, the DSM-600 provides a centralized storage solution with robust data management capabilities, making it easier to store, access, and protect your data in a network environment.

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

Although NAS DSM-600 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.

  • What are the security implications of different file access levels on the D-Link DSM-600 NAS?

    The D-Link DSM-600 NAS (Network Attached Storage) device offers different file access levels that can have various security implications. Here are some of the key implications:

    1. Administrator Access: The administrator has full control over the NAS device, including system settings, user management, and file access permissions. It is crucial to protect the administrator account with a strong password and limit its use to trusted individuals. Unauthorized access to the administrator account could result in complete control over the NAS and its stored data.
    2. User Access: The NAS allows the creation of multiple user accounts with different access privileges. Each user can have their own private folder and access rights to shared folders. Proper user management is essential to ensure that users only have access to the files they need. Weak or shared passwords can increase the risk of unauthorized access and data breaches.
    3. Guest Access: The NAS may provide an option for guest access, allowing users to access specific files or folders without authentication. While this can be convenient, it also poses security risks. If not properly configured, guest access can provide an entry point for attackers to gain unauthorized access to sensitive data. It is important to limit guest access and regularly review the permissions granted to guests.
    4. Remote Access: Many NAS devices, including the D-Link DSM-600, offer remote access capabilities, allowing users to access their files from outside the local network. Enabling remote access introduces additional security considerations. It is crucial to use strong encryption protocols, such as SSL/TLS, to protect data transmitted between the NAS and remote devices. Additionally, enabling two-factor authentication (2FA) can add an extra layer of security.
    5. Firmware Updates: Regularly updating the NAS firmware is essential for security. Firmware updates often include patches for known vulnerabilities and security vulnerabilities. Failure to keep the firmware up to date can leave the NAS exposed to potential attacks.
    6. Network Security: The security of the NAS also depends on the overall network security. Implementing measures like strong passwords, firewalls, intrusion detection systems, and regular network security audits can help protect the NAS from external threats.
    7. Physical Security: The physical security of the NAS device is equally important. Ensure that the NAS is stored in a secure location, preferably in a locked room or cabinet, to prevent unauthorized access or theft.

    In summary, the security implications of different file access levels on the D-Link DSM-600 NAS include the need for strong administrator and user account security, proper configuration of guest access, secure remote access, regular firmware updates, network security measures, and physical security precautions.
