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 Idis 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 recommended practices for protecting NAS Idis DR-1204P devices against physical theft or unauthorized access that can lead to data loss?

Yes, there are several recommended practices for protecting NAS Idis DR-1204P devices against physical theft or unauthorized access. Here are some of them:

Secure Physical Location: Place the NAS device in a secure location that is difficult for unauthorized individuals to access. This could include a locked server room or a locked cabinet.
Restricted Access: Limit physical access to the NAS device by providing access only to authorized personnel. Use keycards, biometric authentication, or other access control mechanisms to ensure only authorized individuals can reach the device.
Surveillance and Monitoring: Install surveillance cameras or use other monitoring systems to keep an eye on the area where the NAS device is located. This can help deter theft and provide evidence in case of any unauthorized access.
Alarms and Sensors: Implement security alarms and sensors that can detect any unauthorized tampering or movement of the NAS device. These alarms can alert security personnel or trigger automated responses to prevent data loss.
Encryption: Enable encryption on the NAS device to protect the data stored on it. This ensures that even if the device is stolen, the data remains encrypted and inaccessible to unauthorized individuals.
Regular Backup and Offsite Storage: Implement a regular backup strategy for the data stored on the NAS device. Make sure that backups are stored offsite, preferably in a secure location, to protect against physical theft or damage to the primary device.
Firmware and Software Updates: Keep the NAS device's firmware and software up to date with the latest security patches. Regularly check for updates provided by the manufacturer and apply them promptly to mitigate any known vulnerabilities.
Strong Passwords: Set strong and unique passwords for accessing the NAS device's administrative interface. Avoid using default or easily guessable passwords to prevent unauthorized access.
User Access Control: Implement user access controls and permissions to restrict access to specific folders or files on the NAS. This ensures that only authorized users can access sensitive data.
Regular Auditing: Conduct regular audits of the NAS device's access logs and user activities to identify any suspicious or unauthorized access attempts. This helps in detecting and preventing potential data breaches.

Remember, implementing a combination of physical security measures, access controls, encryption, and regular monitoring can significantly enhance the protection of NAS devices against physical theft or unauthorized access that can lead to data loss.

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

Although the NAS DR-1204P 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.
