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 specific network security measures to implement for safeguarding NAS Infortrend JB 3060L devices against data loss?
Yes, there are several network security measures that can be implemented to safeguard NAS Infortrend JB 3060L devices against data loss. Here are some recommendations:
- Secure Network Configuration: Ensure that the NAS device is connected to a secure network with proper firewall settings. Limit access to only trusted devices and networks.
- Strong Authentication: Implement strong and unique passwords for accessing the NAS device's administrative interface. Enable two-factor authentication if supported.
- Regular Firmware Updates: Keep the NAS device's firmware up to date to patch any security vulnerabilities. Check for updates regularly and apply them promptly.
- Access Controls: Configure access controls and permissions for users and groups to restrict unauthorized access to sensitive data. Use role-based access control (RBAC) to provide different levels of access based on user roles.
- Encryption: Enable data encryption on the NAS device to protect data at rest. This ensures that even if the physical device is compromised, the data remains encrypted and inaccessible.
- Backup and Disaster Recovery: Implement regular backups of the NAS device's data to an offsite location or cloud storage. This helps in recovering data in case of any data loss or device failure.
- Intrusion Detection and Prevention: Deploy intrusion detection and prevention systems (IDPS) to monitor network traffic and detect any malicious activities or attempts to compromise the NAS device.
- Network Segmentation: Segment the network to isolate the NAS device from other critical systems. This helps in containing any potential attacks and limiting the impact of a security breach.
- Disable Unused Services: Disable any unnecessary services or protocols on the NAS device to reduce the attack surface and potential vulnerabilities.
- Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and address any security weaknesses or gaps in the NAS device's configuration.
It is recommended to consult the manufacturer's documentation and best practices for specific security recommendations for the Infortrend JB 3060L NAS device.
How to take hard disks out of the NAS and connect them to a PC?
Although NAS JB 3060L 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 JB 3060L. 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
JB 3060L has 60 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- RAID 50;
- RAID 60;
- 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 JB 3060L 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.

It is possible to recover data from a NAS Infortrend JB 3060L device that has undergone a file system conversion or re-partitioning, but it can be a complex and challenging process.
First, it is important to note that any attempt to recover data from a device that has undergone significant changes to its file system or partition structure carries a risk of data loss or further damage. Therefore, it is recommended to seek professional help from data recovery specialists who have experience with NAS devices and file system recovery.
The recovery process typically involves using specialized data recovery software or tools to scan the device and attempt to locate and recover the lost or inaccessible data. These tools can analyze the disk's physical structure, file system metadata, and file signatures to identify and extract recoverable data.
However, the success of data recovery depends on several factors, including the extent of the file system conversion or re-partitioning, the condition of the device, and the expertise of the data recovery specialists. In some cases, it may not be possible to recover all the data or to restore it to its original state.
To minimize the risk of data loss and increase the chances of successful recovery, it is crucial to avoid further modifications to the device and to consult with professional data recovery services as soon as possible.
