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 Infortrend also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.
Are there any recommended best practices for securely storing usernames and passwords on NAS Infortrend EonStor GSe Pro 105 devices?
Yes, there are recommended best practices for securely storing usernames and passwords on NAS Infortrend EonStor GSe Pro 105 devices. Here are some of them:
- Change default credentials: The first step is to change the default usernames and passwords provided by the manufacturer. Use strong and unique passwords that are difficult to guess.
- Enable strong authentication: Use strong authentication methods such as two-factor authentication (2FA) or multi-factor authentication (MFA) to add an extra layer of security to the login process.
- Regularly update firmware: Keep the firmware of your NAS device up to date. Firmware updates often include security patches and bug fixes that can help protect against vulnerabilities.
- Use secure protocols: Use secure protocols such as HTTPS or SFTP for accessing and transferring data to and from the device. Avoid using insecure protocols like FTP or HTTP.
- Implement access controls: Set up proper access controls and permissions to ensure that only authorized users have access to the device and its data. Limit access to the necessary users and roles.
- Regularly backup data: Implement a regular backup strategy to ensure that your data is protected in case of any security incidents or data loss. Store backups in a separate location or on a separate device.
- Secure physical access: Ensure that physical access to the NAS device is restricted to authorized personnel only. Keep the device in a secure location and monitor access to it.
- Monitor and log activities: Enable logging and monitoring features on the NAS device to track any suspicious activities or unauthorized access attempts. Regularly review the logs for any anomalies.
- Educate users: Train and educate users on best practices for password security, such as using strong and unique passwords, avoiding password reuse, and being cautious of phishing attempts.
- Regularly audit and review security settings: Conduct regular audits and reviews of the security settings and configurations of the NAS device to ensure that it is properly secured and aligned with best practices.
It is important to note that these best practices are general recommendations and may vary based on your specific requirements and the security policies of your organization.
How to take hard disks out of the NAS and connect them to a PC?
Although NAS EonStor GSe Pro 105 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:
-
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.
-
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.
-
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
-
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.

Restoring data with Hetman RAID Recovery
This program recovers data from damaged RAID arrays and is fully compatible with Infortrend EonStor GSe Pro 105. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.
How to recover data from a Infortrend
EonStor GSe Pro 105 has 5 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- JBOD;
NAS supports:
- exFAT, VFAT, FAT 12 / 16 / 32;
- NTFS / ReFS;
- APFS / HFS+;
- Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
- VMFS / HikvisionFS;
Safe recovery from disk images
This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:
- Overwriting during the recovery process;
- Loss resulting from bad sectors;
- User mistakes.
To create an image, do the following:
-
Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
-
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
-
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
-
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.
Where are user’s files stored?
The Infortrend EonStor GSe Pro 105 network-attached storage keeps OS Linux 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.
