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 Promise 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 software updates and patches enhance the security and stability of NAS Promise VTrak M210p devices?

Regular software updates and patches can enhance the security and stability of NAS Promise VTrak M210p devices in several ways:

1. Security Vulnerability Fixes: Software updates and patches often include fixes for known security vulnerabilities. By regularly updating the device's software, you ensure that any identified security flaws are addressed promptly, reducing the risk of unauthorized access or data breaches.
2. Bug Fixes: Updates and patches also address software bugs and stability issues. These fixes can prevent crashes, system errors, and other issues that may compromise the stability and performance of the device.
3. Compatibility Improvements: Updates often include compatibility improvements with other software and hardware components. This ensures that the NAS device can work seamlessly with the latest operating systems, applications, and network infrastructures, reducing the risk of compatibility-related vulnerabilities.
4. New Security Features: Updates may introduce new security features or enhancements to existing security mechanisms. These additions can provide additional layers of protection against emerging threats, such as improved encryption algorithms, stronger authentication methods, or enhanced access control mechanisms.
5. Firmware Updates: NAS devices like the Promise VTrak M210p often rely on firmware to control hardware components. Firmware updates can address security vulnerabilities or improve the overall functionality and performance of the device. Keeping the firmware up to date is crucial for maintaining a secure and stable NAS environment.
6. Compliance with Industry Standards: Regular software updates ensure that the NAS device remains compliant with industry standards and best practices. Compliance with standards like ISO 27001 or NIST guidelines helps ensure that security controls are in place and reduces the risk of security incidents.

To benefit from these enhancements, it is recommended to regularly check for updates and patches provided by the manufacturer, apply them promptly, and follow best practices for keeping the NAS device's software up to date.

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

Although NAS VTrak M210p 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Promise VTrak M210p. 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 Promise

VTrak M210p has 8 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 1E;
• RAID 3;
• RAID 5;
• RAID 6;
• RAID 30;
• 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:

1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

2. Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.

3. 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.

   

4. 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 Promise VTrak M210p 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.
